Thread ending method and device and parallel processor system

摘要

Each processor comprises a register for storing start address of a forked child thread and a comparator for detecting that the value of its own program counter is coincident with the start address stored in this register. Each processor sends a thread stop notice to a thread controller when the value of its own program counter is coincident with the start address of the forked child thread and ends the execution of a parent thread when receiving a thread end permission from the thread controller.
