SCHEDULING METHOD OF HARDWARE THREAD IN MULTI-THREAD PROCESSOR

摘要

PROBLEM TO BE SOLVED: To provide a multi-thread processor for selecting a flexible hardware thread while ensuring the minimum execution time of a hardware thread.SOLUTION: A multi-thread processor 1 includes: a plurality of hardware threads; a thread scheduler 19 that outputs a thread selection signal TSEL for selecting hardware threads; a first selector 18 that outputs an instruction generated by the hardware thread selected according to the thread selection signal TSEL; and an arithmetic circuit 10 that executes the instruction. The thread scheduler 19 fixedly selects the hardware threads in a first execution period; and selects the optional hardware threads in a second execution period. Ratio between the first execution period and the second execution period and ratio of hardware threads executed in the first execution period are optionally set by a management program that is executed on the arithmetic circuit.
