Processor-based self-detection and abnormality reset system and implementation method thereof

Abstract

The invention discloses a processor-based self-detection and abnormality reset system and an implementation method thereof. The system comprises a self-detection module, a first incrementer, a register, a control module of a processor and other modules of the processor, wherein the self-detection module comprises a second incrementer, a comparer and an increment prestoring device. In this way, by the processor-based self-detection and abnormality reset system and the implementation method thereof, the normal operation of the processor is ensured, electrifying again or replacing hardware is not needed in case of abnormal program running, automatic resetting can be realized during abnormal program running, the processor is more stable in operation, and electrifying again or replacing the hardware caused by abnormal environmental factors or internal factors is avoided.

Description

technical field

[0001] The invention relates to a system for self-detection and abnormality reset, in particular to a processor-based self-detection and abnormality reset system and its realization method. Background technique

[0002] As the core of electronic products, the processor has various abnormal problems during its operation. In some real-time systems, if an electronic product fails to respond abnormally, it will cause economic or other losses.

[0003] Processor operating mechanism: the increment is calculated by the PC incrementer, and the value of the PC register is changed, and the code is read and processed according to this value. There is no detection mechanism to detect the operating mechanism of the PC. When the value of the PC register is not the expected value, the program will run abnormally.

[0004] Today's processors are small in size and are easily affected by factors such as temperature, humidity, and electromagnetic fields in the environment, ma...
