摘要

The processor (100) has a process management unit made of hardware, where management process includes activation and suspension of processes and execution of processes according to their priority. A program memory (101) stores instructions of programs, a data memory (102) stores data manipulated by the programs and an arithmetic logic unit (103) performs arithmetic and logical operations. A controller (104) decodes the instructions and operates the arithmetic logic unit according to decoded instructions, and the process management unit is integrated into the controller.
