Abstract

PURPOSE:To ensure the conflict of requests received from plural external interface by storing these requests into a common table together with the timer value. CONSTITUTION:The trace data production mechanisms 11-1-11-n write the contents of the external process requests into a common table 4 together with the contents of a timer 5. A trace control part 3 reads successively the entries out of the table 4 and checks the timer value stored in the 1st area 41 of the table 4. Then the part 3 checks the number of an interface part stored in a 2nd area 42 of the table 4 at the interval set by the contents of the timer value. The parameter information stored in the 3rd area 43 of the table 4 is delivered to the corresponding interface parts 1-1-1-n for the simulation of the external process requests. In such a way, the requests received plural external interfaces are carried out by allowing these requests from plural external interfaces to be conflicted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an emulator method in a real-time system, and particularly to a method for emulating a case where conflicting processing requests from a plurality of external interfaces occur.

[Conventional technology]

Conventionally, this type of emulator system has held trace information for each external interface, and each piece of trace information has been simulated independently.

[Problem to be solved by the invention]

The conventional emulator method described above has a drawback in that it is not possible to simulate the timing of contention between multiple external interfaces.

[Means to solve the problem]

The emulator method according to the present invention is a real-time system having an information processing device having a plurality of external interfaces for receiving processing requests from the outside, a common table, and a timer, in which each of the external interface units responds to processing requests. and has a trace data creation mechanism that writes the identification number of the interface unit, -9 meter information accompanying the processing request, and the timer value of the timer at the time of the processing request as one entry on the common table. and sequentially read the entries on the common table,
The timing for simulating a processing request is determined based on the timer value, the identification number of the interface unit is checked, and the interface unit having the identification number is assigned the / on the common table.
It has a trace control unit that passes 92 meter information and simulates processing requests.

It is characterized by competing requests from multiple external interfaces and executing them at the same timing as the actual system.

〔Example〕

Next, two aspects of the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

Each information processing device has a trace data creation mechanism 11-
It has a plurality of interface units 1 to 1 to 1-n including 1 to 11-n, accepts processing requests from the outside, and requests data processing to the information processing unit 2.

The trace data creation mechanisms 11-1 to 11-n write the contents of the processing request received from the outside and the contents of the timer 5 into the common table 4. The trace control unit 3 reads the contents of the common table 4 and controls the interface units 1-1 to 1-n.
Simulates the operation of accepting a processing request from the outside.

FIG. 2 is a diagram showing the configuration of the common table 4.

The common table 4 has a plurality of entries, each entry including a first area 41 . for storing the contents of the timer. A second area 4 for storing an interface part number that identifies the interface part that has accepted a processing request from the outside.
2. and information given from outside at the time of processing request.
It is composed of a third area 43 for storing meter information.

Next, the operation of the information processing device will be explained in detail.

Processing requests from the outside are handled by interface units 1-1 to 1-
n is accepted. The request was accepted.

To the trace data creation mechanisms 11-1 to 11-n,
As one entry for one request on the common table 4,
When accepting a request, the content of the timer is sent to the first area 41 to identify the interface units 1-1 to i-n that accepted the request, and the interface unit number is given to the second area 42 from the outside at the time of the processing request. The information thus obtained is stored in the third area as nine-dimensional information. In this way, processing requests from the outside are sequentially stored in the common table 4. The interface units 1-1 to 1-n pass processing requests to the information processing unit 2, and the information processing unit 2 performs necessary data processing.

Next, the emulate operation will be explained in detail.

The trace control unit 3 sequentially reads the entries of the common table 4, checks the timer value stored in the first area 41 in the common table 4, and at intervals according to the contents of the timer value,
Check the interface part number stored in the 20th area 42 in the common table 4.

The parameter information stored in the third area 43 in the common table 4 is passed to the corresponding interface units 1-1 to 1-n to simulate a processing request from the outside. Interface units 1-1 to 1-n c+Similarly to when accepting a processing request from the outside, in the case of a pseudo processing request from the trace control unit 3, the processing request is passed to the information processing unit 2, and the processing request is passed to the information processing unit 2. Perform the necessary data processing in step 2.

〔Effect of the invention〕

As explained above, the present invention allows processing requests from the outside to be stored in a common table with timer values.
Based on the information on the common table, the trace control unit can emulate the operation of the information processing device, including the timing of each processing request, and has the effect that requests from multiple external interfaces can be made to compete. There is.
