Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display output control method for display data across a plurality of screens, and particularly to a display output control method that can speed up display output.

Conventionally, data processing systems that perform processing such as updating, correcting, or erasing various data have been equipped with a center device, a display device, and a control device, and the data across multiple screens of the display device is controlled from the center device. The control device is configured to transmit the received data to the display device and display the data when the control device receives all the data.

However, with these conventional methods, display output is not performed unless all data is received by the control device, and the disadvantage is that it takes a long time from the time the center device issues the data until it is displayed on the display screen. have.

Therefore, an object of the present invention is to provide a display output control system that can immediately output an output in order to eliminate these conventional drawbacks.

In order to achieve the above object, in the present invention, data covering multiple screens is immediately supplied to a display device when the data for the first screen is received, and the data for the first screen is displayed and output, and for subsequent data, the data for the first screen is displayed. Logical combinations (hereinafter referred to as queuing) are performed so that the order can be distinguished and where the data is stored can be determined.

The present invention will be explained in detail below based on examples.

The drawing shows a block diagram of an embodiment of the invention.

In the diagram, the CPU is the center device (hereinafter referred to as host)
D is a display unit (hereinafter referred to as a display), K is a keyboard, and TC is a terminal controller, which is a relay between the display control unit DC and the host CPU. The OS that controls the control is a processing control unit that includes the function of supplying screen data for one screen (hereinafter referred to as page data) to the display unit D, and the LAP is a line controller.
Something that exchanges data with the post CPU,
QCT is a queue controller that performs queuing control, MEM is a memory that stores each page data P ₁ to Pi, and PQT is a paging queue terminal that performs queuing control. It stores the data storage address H, the address T of the final page data, and the address C currently being processed.

Explain the operation.

The post CPU sequentially transfers page data spanning multiple screens to the line controller LAP. Once the data is received, the line controller LAP
Package controller sequentially each time received
Pass data to PAC.

The package controller PAC transfers the received data for only one screen. Simultaneously with reception, this received data is supplied to the queuing controller QCT. cueing controller
The QCT secures a storage area for the received data in the memory MEM, and stores the storage address H for the first page data P of the queuing terminal PQT (hereinafter referred to as the head), the storage address T for the last page data (hereinafter referred to as the tail), and the current The page data storage address C (hereinafter referred to as current) being processed is set. That is, at this time, head H, tail T and current C point to the same page data address. The package controller PAC once outputs the page data to the processing control unit OS and then supplies the page data received from the line controller LAP to the queuing controller QCT.

When the queuing controller QCT receives page data from now on, it updates the data recorded in the page data P ₁ label L stored at the address indicated by the tail T to the address where the next page data is stored, and The tail part T of the queuing terminal PQT is changed to the address where the next page data _P2 is stored. Thereby, page data P ₁ and P ₂ are logically combined.
In the same way, line controller LAP is installed one after another in the same manner.
~ Each page data P ₃ , P ₄ . . . Pi is stored in the memory MEM in a logically connected state through the package controller PAC.

On the other hand, the processing control unit OS supplies the page data transferred as described above to the display unit D, and outputs the page data for display. The operator sees this display and uses the keyboard K.
operate and input data.

Further, when the next page data is required, the operator inputs data to that effect from the keyboard K. The processing control unit OS passes this data to the package controller. package controller
PAC determines that the request is for next page data,
Notify the queuing controller QCT that the following data will be accessed.

Based on this instruction, the cueing controller QCT reads the current part C of the cueing terminal, detects the storage address of the page data P ₁ currently being displayed, accesses the address, and stores the label L of the page data P ₁ . Read out.
As mentioned above, label L contains the next page data P ₂
Since the address of page data _P2 has been written, the queuing controller
The QCT is taken out and delivered to the package controller PAC. The package controller PAC accesses the memory MEM using the passed page address, reads the page data _P2 , and
Supply to OS. The processing control unit OS supplies the received data to the display unit D and outputs the data for display.

Similarly, in response to a request from the keyboard for the next page data, the queued page data is read out and displayed.

As explained above, according to the present invention, when the package controller PAC, that is, the means for supplying a predetermined amount of display data, receives each page data of a plurality of pages supplied from the host CPU, that is, the display data output means, first, , processing control unit for display output
Page data is supplied to the OS, and the page data to be passed from now on is queued to the first page data, so the display output timing is changed to the time when all page data has been passed to the conventional package controller. It can produce effects faster than other products.

[Brief explanation of the drawing]

The drawing is a block diagram of one embodiment of the invention. In the figure, CPC is the center device, TC is the terminal controller, D is the display section, OS is the processing control section,
PQT is a queuing terminal, MEM is a memory, P ₁ , P ₂ ... are page data, and PAC is a package controller.
