ABSTRACT:
In an instruction distribution control device for parallel execution of instructions for use in a superscalar parallel processor, the control device comprises an instruction distribution starting position pointer register, an instruction distribution enable/disable signal generating circuit, and an updating circuit. The distribution starting position pointer register indicates from which instruction of N (>1) instructions the distribution is to be started. The instruction distribution enable/disable signal generating circuit generates signals for determining whether the instructions may or may not be distributed to instruction executing arithmetic units on the basis of the contents of the instruction distribution starting position pointer register and signals indicating the results of dependence analysis for examining resource conflict. The updating circuit generates information indicating to which instruction of the N instructions the execution has advanced on the basis of the instruction distribution enable/disable signals and signals indicating the results of dependence analysis for examining data conflict and updates the instruction distribution starting position indicated by the instruction distribution starting position pointer register.
