Control method of parallel processing type processor system and the parallel processing type processor system

摘要

PURPOSE: To provide the parallel processing type processor system such as a super scolar processor, etc., integrating a trap, which can be processed without prolonging cycle time, and a stall control function. ;CONSTITUTION: This system is provided with N (N is an integer) computing elements 103-106 to execute plural instructions at the same time, instruction supplying means 102 for supplying the instructions to be executed by the N computing elements 103-106, and trap control means for controlling the N computing elements 103-106 so as to abort all the processing of M (M≥N, M is an integer) instructions simultaneously supplied to the N computing elements 103-106 when a processing exception is generated in the case of executing any one of these M instructions while supplying the M instructions from the instruction supplying means 102 to the N computing elements 103106 at the same time. Thus, the control of the trap and stall can be more efficiently executed without prolonging the cycle time and lowering the clock frequency of the system.;COPYRIGHT: (C)1993,JPO&Japio
