PURPOSE:To efficiently execute a competitive test by issuing a sampling start instruction of a competitive operation to a shared device from a monitoring device, and allowing access requirements from each processor to compete with each other on the shared device. CONSTITUTION:The monitoring device 210 issues a micro-instruction to processors 203 - 205 through a path, by which an access to the shared device from its processor is generated at a higher speed than a machine language instruction level, and also, continuously. That is, by the micro-instruction for fetching only the access part in a machine language instruction, a high speed processing can be executed. In such a state, the monitoring device 210 identifies a processing requirement to the shared device issued from the processors 203 - 205, detects automatically the generation of the competition with the processing requirement of other processor, and communicates it with a test program. In such a manner, the competitive test can be executed with high accuracy and efficiently. |
