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 processor comprising:
a first processing section; a second processing section; a controller that controls the first and second processing sections if a fault occurs; and a memory that is shared by the first and second processing sections, and that is configured to be accessed from the second processing section if the fault occurs in the first processing section, wherein the processor is a single chip processor, wherein the memory stores a first program for the first processing section and a second program for the second processing section, wherein the memory further stores a relieving program, the second processing section is interrupted and executes the relieving program when the fault occurs in the first processing section, wherein if the execution result of the relieving program indicates that a priority of the first program is higher than a priority of the second program, the second processing section executes the first program.
