Abstract

PURPOSE: To enable to measure the number of executed instructions accurately and to enable to detect the number of executed instructions by software easily, by incorporating the counter counting the number of executed instructions of the unit itself and the means reading out the content with the instruction.
CONSTITUTION: The instruction from the information processor 11 is enterned to the instruction register 12, the operation code section 13 is interpreted with the instruction interpretion circuit 14, and when it is executed with the instruction execution unit 15, the instruction execution pulse is inputted to the instruction execution number of times counter 17 via the signal line 16 and the value of accumulation is stored. Further, when the storage instruction execution number of times counter (STDS) instruction is entered so that the content of the counter 17 can be read out with software, the unit 15 feeds a signal to the counter 17 via the signal line 18, and the content is fed to the signal line 19. On the other hand, the operand address section 21 designated with STDS instruction is fed to the main memory unit 22 with the address interpretation circuit 22.
