Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to editing processing in an electronic computer.

Editing processing is performed when converting a data representation format that is advantageous for processing in a program into an output format. Editing operations include transferring characters in the sending data as characters in the receiving data, inserting characters that are not in the sending data as characters in the receiving data, and replacing zeros in the upper part of significant figures with blanks. There is. Generally, editing processing is performed by combining the above-mentioned operations. There are several editing processing methods. One of them is the micro-operation method. In the above system, in addition to an edit command that instructs to perform editing processing in a program, there is also a microoperator sequence specified by the edit command. The microoperator column instructs the editing operations such as transfer, insertion, and replacement. Conversion from sending data to receiving data is performed by sequentially interpreting and executing the microoperator sequence specified by the editing command. With the above microphone operation method,
The number of consecutive characters for consecutive transfers or replacements is held in the microoperator. When inserting, the bit string of the inserted character is held in the microoperator or in a special editing table prepared for editing. The present invention relates to the above-mentioned micro-operation system. FIG. 1 shows an example of a conventional micro-operation system.

Edit commands 2 to 8 include an operation code section 2 indicating that the command is an edit command, a sending data instruction word 4 that stores the starting address of the sending data area, and a microoperator string 10.
The microoperator string instruction word 6 stores the starting address of the data on the receiving side, and the receiving side data instruction word 8 stores the starting address of the receiving side data. Microoperator string 10, indicated by microoperator string indicator 6, specifies a series of microoperations to be performed for editing. A sender data storage section 12 is provided to store the data to be edited and is directed by a sender data indicator 4. A receiver data storage section 14 is provided to store the editing results and is instructed by a receiver data indicator 8 . In FIG. 2, one microoperator consists of one byte (8 bits).

Bits 0 to 3 are micro operation code part (MO
P) indicates the type of micro-operation.

Bits 4 to 7 are an information field (IF) that stores information necessary to perform the operation indicated by MOP.

Hereinafter, MOP and IF will be used with the above meaning. An example of editing using the micro-operation method will be explained.

When editing processing indicated by operation code 2 is performed in a certain program, data is read from the sending side data storage section 12 specified by sending side data instruction word 4. Next is micro-operation. The microoperator sequence 10 specified by the operator sequence indicator 6 is read out. Sending side data storage unit 1
The micro-operation specified by the micro-operator column 10 is performed on the data read from the micro-operator 2, and the result is transferred to the receiving data storage section 14. A concrete example of such editing is shown in FIG. The sending data is a 4-digit number string ゜゜123C゛. When a decimal point is inserted between the 2nd and 3rd digits of this data and the sending data is transferred to the receiving data storage unit 14, the microoperator column is RViV2, INSP, MV, as shown in FIG.
It becomes 2. The MOP of MV2 is “MV゛, IF 2゛.” The MOP instructs to transfer the sending side data to the receiving side data storage unit as a micro operation, and the following “゛”
2'' instructs to transfer two digits. FSJSP is MO
It consists only of P and instructs the receiving data storage unit to insert a decimal point as a micro-operation. Executing these micro-operations in order results in the following. Microoperator MV2 executes a micro-operation to transfer the first and second digits "12" from the left of the sending data storage section 12 to the first and second digits from the left of the receiving data storage section 14. Next, the microoperator INSP executes a microoperation to insert a decimal point in the third digit from the left of the receiving data storage section 14.Next, the microoperator MV2 executes a microoperation to insert a decimal point in the third digit from the left of the sending data storage section 12. A micro-operation is executed to move the fourth digit "34" to the fourth and fifth digits from the left of the receiving data storage unit 14, and the editing is completed.
As a result, the receiving side data storage unit 14 has a
The 5 digits of 4 are memorized. In the editing process using the microoperation method, if the number of characters to be edited is variable and determined during program execution rather than before program execution, an operation to rewrite the microoperator's IF is required. For example, in the example shown in Figure 3, the value of "゜2" under microoperator MV2 is changed during program execution. Such an operation causes a decrease in the program execution speed. ~ If more than the maximum number of 155 C characters that can be specified with 7 bits is requested during program execution, editing processing cannot be executed.Also, even if the number of characters is fixed, operations on characters more than 1 monji will not be possible. If required, in the conventional micro-operation method, micro-operators with the same MOP must be written consecutively.For example, when instructing one character transfer, MVl6, MV2
It is necessary to write microoperators with the same MOP one after another, such as. An object of the present invention is to eliminate the above-mentioned drawbacks by providing a storage section in an editing command that indicates a storage device in which the number of characters to be edited is stored, thereby making it possible to realize editing using programmable micro-operations. It provides equipment.

Another object of the present invention is to provide a microoperator with a large number of characters to edit.
Due to the restriction of F, it is necessary to avoid writing the same microoperator continuously and to write it using one microoperator.

The editing command according to the present invention includes an operation code section that instructs editing processing, a sending data instruction word that indicates the location of the sending data storage section where the data to be edited is stored, and an operation necessary for performing editing processing. A microoperator column indicator indicating the storage location of the column of the specified microoperator, a receiving data indicator indicating the storage location where the editing results are stored, and the number of editing characters and insertion characters required by the microoperator specification. It is composed of an edit character count indicator word indicating the storage position of the edit character count storage section where data not described in the microoperator string is stored.

A program including editing instructions, sending data, microoperators, receiving data, and the number of characters to be edited are stored in a storage device. In executing the edit command, the operation code part is decoded by the decoder, and when it is detected that the command is an edit command, the following operations are performed by the control means. That is, the microoperator string of editing commands is sequentially read from the storage device, the sending side data specified in the sending side data instruction section is read out from the storage device according to the read microoperator, and the receiving side data is processed by editing. Store in storage. When performing editing processing, if it is detected that the number of edited characters is stored in the number of edited characters storage section, the value of the storage location of the storage device designated by the number of edited characters instruction word is used. Next, an embodiment of the present invention will be described with reference to the drawings.

The example in FIG. 4 shows information that needs to be stored in the storage device when executing an editing command. The editing processing 22 to 30 is performed by the operation code section 22 and the sending data instruction word 24.
, a microoperator string instruction word 26 , a receiving side data instruction word 28 , and an editing character number instruction word 30 . The operation code section 22 indicates an editing command. The sender data instruction word 24 describes the sender data description section a that describes the data expression format of the sender data storage section 32 in which alphanumeric characters to be edited are stored and the number of characters included in the sender data storage section 32. It includes a sending side data length description section b and a sending side data address description section c indicating the starting address of the sending side data storage section 32. The microoperator string indicator 26 is a microoperator string length description section d that describes the number of bytes occupied by the microoperator string 36 that specifies a series of microoperations necessary for editing, and a microoperator string that describes the starting address of the microoperator string 36. address description part e. The receiving side data instruction word 28 includes a receiving side data description section f that describes the data expression format of the receiving side data storage section 34 that stores the result of editing the sending side data by the microoperator sequence 36, and a receiving side data storage section. It includes a receiving side data length description section g that describes the number of characters included in the section 34 and a receiving side data address description section h that indicates the starting address of the receiving side data storage section 34. Edit character count indicator 30
is used to refer to the edited character number storage unit 38 which stores data that is not included in the microoperator string 36 or the editing table, such as the number of edited characters and inserted characters. The edit character number indicator 30 includes a data length description section that describes the byte length of the edit character number storage section 38, and a data address description section j that describes the address of the edit character number storage section 38. A program including the editing commands 22 to 30, the sending data storage section 32, the receiving data storage section 34, the microoperator column 36, and the editing character number storage section 38 are set in a storage device. The edited character number storage section 38 stores data that is not included in the microoperator string 36 or the editing table, such as the number of edited characters or inserted characters required when executing a microoperator. Edited character number storage unit 38
can be referenced and rewritten by commands other than editing commands. Here, the configuration of micro-operators that instruct micro-operations necessary for editing as elements of the micro-operator column 36 is shown. Each microoperator has 1
It consists of bytes, and bits 0 to 3 are the micro-operation code part (MOP), which specifies the editing operation to be executed by this micro-operation. Bits 4 to 7 are the information field (IF) and contain information necessary to perform the operation specified by the MOP.

Depending on the type of MOP, one extra byte of information may be included following 1F if the lower part is not required. FIG. 5 is a block diagram of one embodiment of a programmable micro-operation editing device according to the present invention.

FIG. 5 will be explained below. The storage device 40 stores the program including the editing instructions shown in FIG. 4 and the sending data storage section 3.
2, the receiving side data storage section 34, and the microoperator column 3
6 and an edited character number storage section 38. address register 4
2 designates a read position when reading information from the storage device 40 or a write position when writing information. Instruction register 44 stores the operation code of the instruction. Decoder 46 identifies the operation code in instruction register 44. The sending side data address counter 48 indicates the storage address of the sending side data. Each time one digit of the sending data is edited, it counts up and indicates the position of the next digit to be edited. A microoperator address counter 50 indicates the address of a microoperator, and is incremented when execution of one microoperator is completed, and indicates the address of the next microoperator. The receiving side data address counter 52 indicates the storage address of the receiving side data. Each time the editing result of one digit is stored in the receiving side data storage section 34, it is counted up to indicate the position where the next edited digit is stored. The number of edited characters storage address instruction register 54 stores the address of the number of edited characters storage section 38 that stores the number of edited characters used by the microoperator. counter 4
When reading from or writing to the main storage device 40 using the addresses indicated by the registers 54 and 8 to 52, at. This is done via the address register 42. The memory register 56 stores information read from the storage device 40 or information to be written.
The MOP register 58 stores the MOP indicated by bits 0 to 3 of the microoperator via the memory register 56. The MOP decoder 60 decodes 4 bits of the MOP register 58 to identify the MOP. Edit character number counter 62 is used by a particular microoperator and counts down when a microoperation is performed on a digit. The fact that there are no more characters to edit with the microoperator is indicated by the value of the edit character counter 62 becoming O.The initial value is the microoperator's value stored in the storage device 40 or the edit character count memory. The value of section 38 is stored in edit character number counter 62 via memory register 56. If the data in the editing character count storage unit 38 is an insertion character from the operation instructed by the MOP, the data is transferred from the storage device 40 to the memory register 4.
The insertion data read out to 0 is written to the receiving data storage section 34 of the storage device 40. The zero check device 64 performs a zero check on the contents of the edited character number counter 62. When the check result of the check device 64 is zero, the gate 66 inputs the edited character number storage address instruction register 5.
It is used to transfer the value of 4 to the address register 42 and not perform the transfer when the check result of the zero check device 64 is not zero. Edit command control device 6
8, when the output line of the edit command of the decoder 46 is activated,
Provides the necessary controls to execute editing instructions. The editing command control device 68 consists of a flip-flop for creating control timing and a logic element for checking conditions necessary for control. The microoperator control device 70 is a control device for performing microoperations according to the output line energized by the MOP decoder 60. The microoperator control device 70, like the editing command control device 68,
It consists of flip-flops that create control timing and logic elements that check the conditions necessary for control. In order to explain the specific editing process based on this example,
FIG. 6 shows an example of data instructed by an editing command and immediately before the microoperator executes the editing command. The sending side data storage unit 32 consists of n digits, the contents of which are 661278.
・・・・・・゛.

The receiving side data storage section 34 consists of m digits, and its number is assumed to be ΔΔ . . . Δ”. The editing operation here is to first insert "゜\\" and then move the following one character (I is a variable) from the sending data storage to the receiving data storage.The microoperator string is As shown in Figure 6, it is written as ISC..IVVOOOO.■NSC
is a microoperator that specifies the operation of inserting ゜゜\゛ into the receiving data storage unit. Micro operator M
The MV, which is the MOP of VOOOO, specifies the operation of transferring data from the sending data storage to the receiving data storage. The number of digits of the transfer data is shown in ■F of the microoperator. However, if the 4 bits of IF are ゜゜000σ゛, the contents of the edited character number storage section 38 are taken as the number of digits to be transferred.
In FIG. 6, since it is MVOOOO, the content 1 of the edited character number storage section 38 is the number of digits to be transferred. From FIG. 6, since the I value immediately before the editing command is executed is 00...00100, it means that 4-digit transfer is specified. Such editing operations will be explained using FIGS. 4, 5, and 6.

The operation code section 22 is stored in the instruction register 44. As a result, the output line indicating the editing command is activated in the decoder 46, and the editing command control device 68 performs the following editing process. Address description portion C of the sending data indicator 24, microoperator string indicator 26, receiving data indicator 28, and edit character count indicator 30 in FIG.
ehj is read from the storage device 40 via the memory register 56, and the sending side data address counter 48,
The data is stored in the microoperator address counter 50, the receiving side data address counter 52, and the edited character number storage address instruction register 54. At this time, an expansion operation to a real address is performed as necessary. The contents of microoperator address counter 50 are transferred to address register 42 and the first byte of microoperator 36 is read from storage 40. The 0th to 3rd bits of the read microoperator are stored in the MOP register 58 via the memory register 56, and the 4th to 7th bits are stored right-justified in the edit character number counter 62, and all upper bits are set to 0. Make it. In this example, from Figure 6,
INSC is stored in the MOP register. MO this
When decoded by the P decoder 60, INSC. The output line shown is energized. The energized signal causes the microoperator controller 70 to
The operation to insert "゜\" is started. When inserting, the contents of the receiving side data address counter 52 are transferred to the address register 42, and the left side of the receiving side data storage section 34 shown in FIG. Store “\゛” in the first digit from (the position specified by the address register). When this operation is completed, the value of the microoperator address counter 50 is counted up to indicate the position of the microoperator following the INSC microoperator in the microoperator column 36. Also, the value of the receiving side data address counter 52 is counted up, and the value of the receiving side data storage unit 3 is counted up.
The content indicates the second digit from the left of 4. Next, the contents of the microoperator address counter 50 are transferred to the address counter 42, and the microoperator in the second byte of the microoperator column 36 is read out. From FIG. 6, the microoperator read at this time is MVO
It's OOO. Via the memory register 56, the MOP register 58 stores 0 to 3 bits (MOP) of this microoperator, and the edit character number counter 62 stores 4 to 7 bits (IF) right-aligned. At the same time, all upper bits are set to O.The MOP decoder 60 sets M
Decoding the contents of the OP register energizes the output line indicating M■. The activation signal causes the microoperator controller 70 to initiate the operation of transferring characters from the sending data store 32 to the receiving data store 34. The contents of the edited character number counter 62 are checked by a zero check device 64, and if it is not 0, the contents of the edited character number counter 62 are set as the number of transferred characters necessary for performing the MV operation. In the example shown in FIG. 6, the IF value is 0000, so the content of the edited character number counter 62 is O. In this case, the gate 66 is opened by a signal from the zero check device 64. As a result, the contents of the edited character number storage address instruction register 54 are transferred to the address register 42, and the edited character number storage section 38 is transferred to the address register 42.
Read out. The read contents of the edited character number storage unit 38 are sent to the edited character number counter 62 via the memory register 56.
is stored in The value stored in the edit character number counter 62 becomes the number of characters to be transferred required to perform the MV operation. From Figure 6, the contents of the editing character number storage section are “0...001”.
Since it is 00゛, the number of characters to be transferred is 4 digits. In order to transfer characters from the sending data storage section 32 to the receiving data storage section 34, the following operation is performed. The contents of the sending side data address counter 48 are transferred to the address register 42. The first character from the left of the sending data storage section 32 specified by the address register 42 is read out from the storage device 40 to the memory register 56. Next, by transferring the contents of the receiving side data address counter 52 to the address register 42, the contents of the memory register 56 are stored in the position indicated by the receiving side data address counter 52. Since the contents of the receiving side data address counter 52 indicate the second digit from the left of the receiving side data storage section 34, the contents of the memory register will be stored at this position. In these operations, as shown in FIG. 6, the character ゜゛1゛ is read from the first digit from the left in the sending data storage section 32, and the character ゜゛1゛ is read from the second digit from the left in the receiving data storage section 34. written. As a result, the data storage section on the receiving side becomes as shown in FIG. After the transfer of this one character is completed, the value of the sending side data address counter 48 is counted up to indicate the second digit from the left of the sending side data storage section 32.
Furthermore, the value of the receiving side data address counter 52 is counted up to indicate the third digit from the left of the receiving side data storage section 34. The value of the edited character number counter 62 is counted down, and the content of the counter 62 is checked by the zero check device 64. If it is 0, the microoperation instructed by the microoperator is completed. In the example shown in FIG. 6, the content of the edited character number counter 62 that has been counted down is 3, so characters are subsequently transferred from the sending data storage section 32 to the receiving data storage section 34. The above operations are performed on the values of the counters 48, 52, and 62 every time one character is transferred.

Transfer is performed until the content of the edited character number counter 62 becomes 0 and the check result of the zero check device 64 becomes zero. If the check result is zero, this micro-operation ends. Since the microoperator executed here is located at the end of the microoperator sequence, the execution of the editing command also ends when the execution of this microoperator ends. FIG. 8 shows the contents of the receiving data storage section at the end of the editing command. In the above editing process, the case where there is only one editing character number storage section 38 has been described. In order to perform editing processing other than the editing processing described above, there may be cases where two or more editing character number storage units are required.

In other words, this is the case when variables that can be programmed by two or more microoperators are handled in a microoperator sequence. In the above case, an edit character number indicator is added to the command according to the number of variables. The added editing character number instruction words each indicate the corresponding editing character number storage unit (storage unit in which variables are stored). By the means described above, editing processing that requires two or more editing character number storage units can be performed. As described above, according to the programmable micro-operation editing method according to the present invention, the number of editing characters and inserted characters can be changed during program execution without changing the information in the micro-operator string. Editing processing can be performed in accordance with data that is not written.

In the conventional micro-operation method, when performing programmable editing, the contents of the storage area of variables that can be changed by the program are changed, and the micro-operator's I
It is necessary to rewrite the data in the F or microoperator string, which deteriorates performance. Furthermore, the number of editable characters is limited by the bit length of the IF. The present invention has the effect of solving the above problems. Furthermore, compared to the conventional method in which the number of characters to be edited is limited by the bit length of the IF, according to the present invention, by increasing the number of bits in the number of edited characters storage section, editing can be performed even when the number of characters to be edited is large. I can do it. Furthermore, there is an advantage that the microoperator string can be shared by several editing commands that perform the same editing operation but differ only in the number of edited characters or the type of inserted characters.
