DETAILED DESCRIPTION OF THE INVENTION A description will be given below with reference to the drawings. First, the configuration of the designing or tuning apparatus according to the embodiment of the present invention will be described. FIG. 1 is a diagram showing a configuration of a designing or tuning apparatus according to an embodiment of the present invention. In FIG. 1, a source program 1 written according to the rules of a programming language, a compiler 2 for translating the source program 1 into an object code, and a master processor 3 serving as a master are arranged.

The compiler 2 compiles the source program 1 into an execution program based on the designated compile options and stores the information in the compile information 6.

The master processor 3 is equipped with various resources as much as possible and has a function of reporting the usage status of the resources. The master processor 3 is used to execute the above-mentioned execution program to confirm the correctness of the program. At the same time, data collection such as resource usage and performance in the master processor 3 is fed back to the compiler 2 via the report 4.

The compiler 2 uses the compilation information 6 described above.
Based on the information fed back via the report 4 and the report 4, the usage method and configuration of the resource that optimizes the performance of the master processor 3 are derived, and the conditions for compiling the source program 1 are stored in the compilation information 6. Also, the type, quantity, and configuration of required resources are parameterized, output as processor information 5, and fed back to the LSI vendor.

Next, a design or tuning method according to the embodiment of the present invention will be described. FIG. 2 is a flowchart showing a design or tuning method according to the embodiment of the present invention. In FIG. 2, first, the processor 3 (see FIG. 1) that is the master is prepared (step 1),
A program is developed using this master processor 3.

The compiler 2 (see FIG. 1) compiles the source program 1 (see FIG. 1) into an execution program based on the designated compile options and the like (step 2). This information is stored as compilation information 6 (see FIG. 1).

Then, using the master processor 3,
The above-mentioned execution program is executed (step 3), and the correctness of the program is confirmed. At the same time, data collection such as resource usage and performance in the master processor 3 is fed back to the compiler 2 via the report 4 (see FIG. 1) (step 4).

The compiler 2 uses the compilation information 6 described above.
Based on the information fed back through the report 4 and the report 4, the usage method and configuration of the resource that optimizes the performance of the master processor 3 are derived, and the conditions for compiling the source program 1 are stored in the compilation information 6 (step 5). Also, the type, quantity, and configuration of the required resources of the master processor 3 are parameterized and output as processor information 5 (see FIG. 1) (step 6).

As is apparent from the above description, according to the present invention, it is possible to design or tune a central processing unit or computer system specialized for each application.

In particular, LSI (Large Scale Integratio)
n) For vendors, the resource requirements and cost performance at the development site of the user who creates the application can be obtained in real time without considering the development status of the emulator and the speed difference between the emulator and the actual device, and is optimal for that requirement. Any central processing unit or computer system can be designed or tuned.

Further, for the user, the central processing unit or computer system having the best cost performance can be installed in a short period of time and at a high level without introducing an emulator that cannot be operated at an actual speed due to a huge introduction cost during development. Will be available without the need for specialized expertise. Further, in the past application development of the user, it becomes possible to utilize the data such as the usage status of the resource of the device which could not be capitalized up to now for the development of a new application.
