PROCESSOR AND METHOD OF CONTROLLING EXECUTION OF PROCESSES

摘要

A processor includes a plurality of processing sections, each of which executes a predetermined process. A plurality of fault detecting circuits are respectively provided for the plurality of processing sections, to detect a fault in one of the plurality of processing sections as a fault processing section to generate a fault detection signal. A fault monitoring and control section controls a normal processing section as at least one of the plurality of processing sections other than the fault processing section to execute a relieving process in response to the fault detection signal. The relieving process is determined based on a process load of the fault processing section, a process load of the normal processing section, and priority levels of processes to be executed by the fault processing section and the normal processing section.

主权项

1. A multi-processor system comprising:
a first processor; a second processor; a memory circuitry that is shared by the first and second processors, and that stores a first program for the first processor and a second program for the second processor; a first bus coupled to the first processor; and a first detecting circuitry that detects a bus error on the first bus, wherein when the first detecting circuitry detects the bus error, the second processor interrupts a running process for the second program and determines whether to execute either the first program or the second program, and wherein the multi-processor system is included in a single chip.
