BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program analysis method for a multiprocessor system having a plurality of processors.

[0002]

2. Description of the Related Art In the conventional program analysis method of a multiprocessor system, when two processors have different program analysis points for one event, the two processors each have an ICE (In-Circuit Emulator; Connect the following simulated device).

This will be described with reference to FIG.
FIG. 3A is a block connection diagram showing an example of the related art, and FIG. 3B is a flowchart showing an example of the main operation procedure according to FIG. 3A.

The illustrated main processor 41 and local processor 42 are two processors forming a multiprocessor, and the control program of the local processor 42 is executed subsequently to the control program of the main processor 41.

The program analysis simulation device 40 for this event has an analysis program, which is first connected to the main processor 41 (procedure 101), the first analysis point is designated, and the analysis program is set (102). To do.

When the event is started, the main processor 41 is activated (103) and the control program is executed (10).
4) When the analysis program is executed at the first analysis point, the execution is stopped (105) at the end of this process.

Here, the simulation device 40 returns to the steps 101 and 102 for changing the connection to the local processor 42, designating the second analysis point and setting the analysis program. When the event is restarted, the local processor 42 is activated, the control program is executed, the analysis program is executed at the second analysis point, and steps 103 to 105 in which the processor is stopped are executed.

The simulator 40 executes a necessary program analysis in the state of the procedure 105 in which the processor is stopped.

Since the connection between the simulation device and the processor is complicated and complicated, generally, an expensive simulation device is connected to each of a plurality of processors by temporarily suspending the operation of the processor.

[0010]

The above-described conventional program analysis method for a multiprocessor system is uneconomical because a simulation device is connected to each of a plurality of processors, and it is necessary to suspend the system. Even when the process at the set analysis point is executed, a complicated operation is required to set the next analysis point after the program analysis is executed by the temporary stop of the process and then restart the stopped process. there were.

An object of the present invention is to incorporate an analysis support program in each of a plurality of processors, and when an event occurs when an analysis point is designated by one system processor, the analysis support program is executed at this analysis point. Then, the program analysis of the multiprocessor system that solves the above problems is provided by proceeding to the execution of the preceding program.

[0012]

According to a program analysis method of a multiprocessor system according to the present invention, a maintenance terminal for designating a program analysis point for each of the processors by a predetermined procedure and a designated maintenance terminal connected to the maintenance terminal. The processor has one system processor that sets a program analysis point to be input and outputs a program analysis result from the processor to the maintenance terminal, and the processor sets the program analysis point from the system processor. When this point is received, the analysis support program built in this point is inserted, and when the processing for one event passes this point, the analysis processing of the program is executed, and the program analysis result is sent to the system processor by the instruction of this program Output With a stage.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a software control diagram of program analysis in a processor showing an embodiment of the present invention, and FIG. 2 is a processor configuration diagram for explaining FIG.

First, as shown in FIG. 2, the exchange 1 has a plurality of processors, namely, a system processor 10, a main processor 20 and a local processor 30, and these processors are bus-connected. Further, the system processor 10 is connected to the maintenance terminal 2 with a connection cable.

On the other hand, as shown in FIG. 1, each of the main processor 20 and the local processor 30 has a control program 21, 31 for exchange control and a support program 22, 32 for analysis. The analysis support programs 22 and 32 are the same common program.

Next, the program analysis procedure will be described with reference to FIG. 1 and FIG.

First, when the first analysis point 23 and the second analysis point 33 are input from the maintenance terminal 2 by designating the processors 20 and 30, respectively, the system processor 10 inputs the first analysis point 23 to the main processor 2.
0 control program 21 and second analysis point 3
3 in the control program 31 of the local processor 30,
Transfer and set each.

When an event occurs, the main processor 20
Executes the control program 21 and the first analysis point 2
When the processing of No. 3 is executed, the main processor 20 relays the exchange control and shifts the processing to the analysis support program 22 for analyzing the program.

The analysis support program 22 confirms the generated event as a program analysis event, executes the analysis processing of the program, stores the result in the analysis processing storage area 24, and then interrupts the control program 21 for exchange control. The exchange control is restarted from a certain point, and after the processing is executed according to the control program 21, the event information is transferred to the local processor 30.

When the local processor 30 executes the control program 31 for exchange control and executes the processing at the second analysis point 32, the exchange control is interrupted and the analysis support program 32 is processed as in the case of the main processor 20. Transfer.

The analysis support program 32 confirms that the event being processed is a program analysis event, executes the analysis processing of the program, and stores the result in the analysis processing storage area 34.

The analysis support programs 22 and 32 store the analysis results in the analysis result storage areas 24 and 34, respectively, but the system processor 10 relaying the analysis points from the maintenance terminal 2 analyzes the analysis results of the last analysis point 32. Received from the result storage area 34, transferred to the maintenance terminal 2,
It is displayed on the maintenance terminal 2. Of course, if there is necessary information, the maintenance terminal 2 can instruct the system processor 10 to obtain the result information from the analysis result storage area 24.

[0024]

As described above, according to the present invention, each of a plurality of processors has a built-in analysis support program, and the system processor relays and sets the analysis point of the program and the collection of the analysis result from the maintenance terminal. By doing so, it is possible not only to input multiple analysis points across multiple processors from the maintenance terminal, but also to improve the economic efficiency by eliminating the need for a simulation device and improve the operational aspects by not stopping the exchange. is there.
