Abstract

PURPOSE:To evaluate an input/output control program without using an actual control adapter or input/output device by using a package for simulation and a personal computer to simulate the function of an access instruction issued from an input/output control program and returning results. CONSTITUTION:When an instruction IN or OUT is outputted to a bus 3 in accordance with execution of an input/output control program 2, a package 4 for simulation converts this outputted access instruction to a form adapted to simulation software and gives it to a personal computer 8. Simulation software 9 on the personal computer 8 simulates the function of the access instruction, and the package 4 for simulation outputs simulation results to the bus 3. Thus, the input/output control program is evaluated without actually connecting the input/output control program 2 to a control adapter and an input/output device as the control object.

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an example of a data processing device to which the input/output control program evaluation method of the present invention is applied.

As shown in the figure, in this embodiment, the input/output control program 2
A simulation package 4 is connected to a bus 3 of a data processing device that includes a memory 1 and a processor 11, and a personal computer (hereinafter abbreviated as a personal computer) 8 is connected to this simulation package 4.

An external recording device 10 is connected to the personal computer 8.
From there, the simulation software 9 is preloaded and ready for execution. This simulation software 9 determines what to notify the human output control program 2 of the data processing device when an IN command is issued to which I/O address, according to the specifications of the control adapter to be controlled by the human output control program 2. Functions such as
When the /O command is issued, functions such as storing the output data in a pseudo manner at a specified I/O address and returning what as a response are programmed.

On the other hand, the simulation package 4 includes a bus interface circuit 5, a conversion circuit 6, and an RS232C interface circuit 7, and is connected to the bus 3 by the bus ink face circuit 5, and connected to the personal computer 8 by the RS232C interface circuit 7. Ru. Here, the conversion circuit 6 receives the access command outputted to the bus 3 along with the execution of the human output control program 2 from the bus interface circuit 5, and converts it into a format suitable for the simulation software 9. Converts the contents of the access command into an I/O address, data, and information distinguishing between IN/OUT commands,
It sends it to the personal computer 8 via the RS232C ink face circuit 7, and outputs the simulation result received from the personal computer 8 via the RS232C interface circuit 7 to the lotus 3 via the lotus ink face circuit 5 as the result of the access command. It is a circuit.

Next, the operation of this embodiment configured in this manner will be explained.

When the input/output control program 2 issues an IN command to the bus 3 while actually executing the human output control program 2 stored in the memory 1 for evaluation, the IN command
Instructions are sent to bus 3 and simulation package 4.
The conversion circuit 6 is notified through the bus interface circuit 5. The conversion circuit 6 converts the IN command instructed by the human output control program 2 into information indicating that it is an IN command and an I/O address, and transmits the information to the personal computer 8 through the RS232C ink face circuit 7.

The simulation software 9 on the personal computer 8 is R.
When the above information is transmitted through the S232C ink face circuit 7, the I/O address of the concerned I/O address is programmed in accordance with the specifications of the control adapter.
A synthesis is performed to determine what should be notified in response to the N command, and the result is transmitted to the conversion circuit 6 of the simulation package 4 through the RS232C ink face circuit 7.

The conversion circuit 6 outputs the transmitted contents to the lotus 3 through the lotus ink face circuit 5, and returns a response to the IN command to the input/output control program 2.

As a result of the above-described simulation, the input/output control program 2 appears to be outputting an IN command to the actual control adapter and input/output device. Although the above example concerns an IN command, a similar simulation is performed when the human output control program 2 issues an OUT command. Therefore, by observing the behavior of the input/output control program 2 in the same manner as in the past, it is possible to evaluate the input/output control program 2.

〔Effect of the invention〕

As explained above, according to the evaluation method of the input/output control program of the present invention, the simulation package connected to the bus of the data processing device and the personal computer further connected to the simulation package are used to evaluate the output from the input/output control program. It is possible to simulate the functions of access commands and return the results to the input/output control program, making it possible to evaluate the input/output control program without using actual control adapters or input/output devices.
