Problems solved by technology

[0004] Aiming at the problem that the reset time of the multiprocessor system is relatively long in the prior art, the present invention proposes a system and method for multiprocessor reset control and watchdog monitoring. When the processor crashes, only the auxiliary processor needs to be reset, and there is no need for a global reset, thereby reducing the system reset time

Abstract

The invention discloses a system and method for multiprocessor reset control and watchdog monitoring, and the system comprises a logic control unit, the logic control unit is internally provided with n watchdog monitoring modules, and the n watchdog monitoring modules are connected with n processors in a one-to-one correspondence manner, and are used for receiving dog feeding signals of the corresponding processors; the n processors comprise a main processor and n-1 auxiliary processors, and when the watchdog monitoring module detects that a dog feeding signal is interrupted, a reset signal is sent to the corresponding processor for resetting. According to the method, main and auxiliary classification is carried out on the processors, when the auxiliary processor crashes, only the auxiliary processor needs to be reset, global reset is not needed, and therefore the reset time of the system is shortened.

Description

technical field [0001] The invention relates to the technical field of electronic control, in particular to a system and method for multiprocessor reset control and watchdog monitoring. Background technique [0002] With the development of science and technology, in the design of modern electronic circuits, the functions of electronic systems are becoming more and more powerful, which requires the cooperation of multiple processors, and strict reset control and watchdog monitoring are required between each processor. [0003] The existing reset and control system adopts an independent or unified reset source, the watchdog cannot be controlled independently, and cannot meet the requirements of flexible operation of the existing system, and the system does not have a separate control of the main and auxiliary processors, and a global reset is often required after the system is abnormal , which increases the system reset startup time, and the system work efficiency is compromis...
