DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for collecting and processing data of continuous images taken by, for example, a television camera or the like using a data processing device such as an electronic computer.

First, a conventional wave height distribution analysis data processing method shown in FIG. 1 will be briefly described.

In Figure 1, 1 is a data register that stores measured data for analyzing wave height distribution, 2 is a base address register that stores a reference base address, and 3 is an adder that adds the base address and measured data. 4 is a control circuit A that controls the addition of measurement data and a base address and controls the transfer as a storage address; 5 is a data processing device; 6 is a storage device that stores wave height distribution analysis data; Read the contents of the storage address of the storage device,
1 and stores the result in the storage device again; 8 is a memory bus that couples the data processing device or high-speed data bus control device with the storage device; 9 is a memory bus for storing storage addresses, etc.; 10 indicates a high speed data bus for transferring control device information for controlling the control circuit A and a low speed data bus for transferring base addresses, etc. to the base address register.

Now, after the data processing device 5 gives a measurement data collection start command to the control circuit A4 through the low-speed data bus 10, when measurement data for wave height distribution analysis is measured, this data is stored in the data register 1. The control circuit A4 receives the base address previously set in the base address register 2 from the data processing device 5 via the low-speed data bus 10, and notifies the control circuit A4 of the completion of data storage.
It controls the transfer of the address and the measurement data stored in the data register 1 to the adder 3.

The adder 3 adds the base address and the measurement data and transfers the result as a storage address to the high-speed data bus controller 7 via the high-speed data bus 9.

Next, the high speed data bus controller 7 reads the contents of the storage address from the storage device 6 through the memory bus 8, adds 1, and stores this result back to the storage device 6 through the memory bus 8.

After performing the above operation for a predetermined period of time, the data processing device 5 gives a measurement data collection stop command to the control circuit A4 through the low-speed data bus 10, and then the data processing device 5
represents the wave height distribution analysis data stored in the storage device 6,
Data is sequentially read out through the memory bus 8 and data processing is performed.

Thereafter, the data processing device 5 initializes all the contents of the storage device 6 via the memory bus 8 in preparation for collecting new measurement data.

In this conventional wave height distribution analysis data processing method, the data processing device 5 is occupied in order to initialize the contents of the storage device 6, and the start of collecting new measurement data is delayed.

For this reason, the time period during which measurement data cannot be collected increases significantly.
This method has the disadvantage that it cannot be applied to data processing of continuous images taken by a camera or the like.

This invention solves the above-mentioned drawbacks, and includes a plurality of base address registers & counters that store pace addresses and add up one by one, and an initial register that stores data for initializing the measurement data storage area. One setting data register and one length register & counter for storing the size of the measurement data storage area are provided, and a plurality of measurement data storage areas are secured in the storage device,
A base address is set in advance in the plurality of base address registers and counters from the data processing device, and measurement data is collected.

Next, after a predetermined period of time, the base address is switched by a base address switching command from the data processing device, and while continuing to collect measurement data, the measured data storage area of the storage device before switching from the data processing device is initialized. By initializing through a high-speed data bus with a configuration command,
This paper proposes a wave height distribution analysis data processing method that eliminates time periods during which measurement data cannot be collected and enables continuous image data processing.

Embodiments of the present invention will be described below with reference to the drawings.

In Figure 2, 1 is a data register, 3 is an adder,
5 is a data processing device, 6 is a storage device, and 7 is a high-speed data processor.
Bus control device, 8 is a memory bus, 9 is a high-speed data bus, 10 is a low-speed data bus, 11 is a base address register & counter A, 12 is a base address register & counter B, 13 is a select circuit , 14 is a control circuit B, 15 is an initial setting data register for storing data for initializing the measurement data storage area, and 16 is a length register for storing the size of the measurement data storage area.
It is a counter.

In this configuration, low-speed data is transmitted from the data processing device 5.
Through the bus 10, the base address is given to the register section and counter section of the base address register & counter A11 and the base address register & counter B12, respectively, and at the same time, the initial setting data register 1
5 contains data to initialize the measurement data storage area,
After setting the sizes of measurement data storage areas in the register section and counter section of the length register and counter 16, a command to start collecting measurement data is given to the control circuit B14.

When the measurement data for analyzing the wave height distribution is measured, this data is stored in the data register 1, and the completion of data storage is notified to the control circuit B14.

In the control circuit B14, the select circuit 13 first transfers the base address of the register section of the base address register & counter A11 to the adder 3, and at the same time also transfers the measured data of the data register 1 to the adder 3.

The adder 3 adds the above two data and transfers it to the high speed data bus controller 7 through the high speed data bus 9 as a storage address.

Next, the high speed data bus controller 7 reads the contents of the storage address from the storage device 6 through the memory bus 8, and
1 is added and this result is sent back to the storage device 6, and then sent to the memory bus 8.
to remember through.

After performing the above operation for a predetermined time, the data processing device 5 sends a base address switching command to the control circuit B14 through the low-speed data bus 10 to cause the select circuit 13 to select the base address register & counter B12, and performs measurement. Continue data collection.

On the other hand, after giving the base address switching command through the low-speed data bus 10, the data processing device 5 processes the data in the measurement data storage area of the storage device 6 before switching, and after completing the processing, transfers the base address to the low-speed data bus 10. through control circuit B14
A command to start the initial setting of the measurement data storage area of the storage device 6 before switching is given.

The control circuit B14 uses the base address register & counter A11 during the idle time of the operation to transfer the storage address to the high-speed data bus controller 7 through the high-speed data bus 9.
is selected by the select circuit 13, and in the adder 3, only the base address of the counter section of the base address register & counter A11 is stored as a storage address, and then the base address of the counter section of the base address register & counter A11 is determined. 1 is added to the base address of the length register and counter 16, and 1 is subtracted from the length of the count section of the length register and counter 16. At the same time, the select circuit 13 is switched again to the base address register and counter B12.

Next, the control circuit B14 initializes the initial setting data register 1.
5, the preset initialization data is transferred to the high-speed data bus controller 7 through the high-speed data bus 9 at the same time as the storage address.

The high-speed data bus control device 7 causes the storage device 6 to store the transferred initial setting data at the transferred storage address through the memory bus 8.

Also, if the completion of storing new measurement data has not come from the data register 1 to the control circuit B14, and the content of the counter section of the length register & counter 16 is 0.
If not, the control circuit B14 causes the select circuit 13 to select the base address register & counter A11 again, and performs the operation of initializing the measurement data storage area until the contents of the counter section of the length register & counter 16 are Repeat until it reaches 0.

Next, the control circuit B14 sets the data in the register part of the length register & counter 16 to the counter part by detecting that the content of the counter part of the length register & counter 16 is 0, and also sets the data in the register part of the length register & counter 16 to the counter part. An initialization completion signal is transferred to the data processing device 5 via the bus 10.

Further, the base address data of the register section of the base address register & counter 11 is set in the counter section.

Thereafter, the data processing device 5 causes the base address register & counter B12 to collect the measurement data again after a predetermined period of time has elapsed, and then returns the measurement data from the base address register & counter B12 to the base address register & counter A11 to the control circuit B14. Base address switching instruction,
The data is transferred through the low-speed data bus 10, and measurement data is collected again using the base address of the base address register & counter A11.

In this case, base address register & counter A1
Since the base address of the register section 1 is held as the base address set in advance by the data processing device 5, there is no need to reset the base address.

As explained above, according to the embodiment of the present invention, there are a plurality of base address registers & counters, one initial setting data register for storing data for initializing the measurement data storage area, and one initial setting data register for storing the data for initializing the measurement data storage area.
