Problems solved by technology

However, since the signal stack may be adjacent to the space used to store data in the heap memory, when the data is written out of bounds, the signal stack will be stepped on, resulting in the failure of signal processing

Abstract

An embodiment of the invention provides signal processing method and device capable of ensuring the signal processing. The method includes that first memory capacity required in operating target thread and second memory capacity required by the target thread in signal processing are determined; thread stack is established according to the first memory capacity and the second memory capacity, wherein the thread stack includes a stack storage space and a signal storage space, the stack storage space is used for storing process variation generated in operating the target thread, the stack storage space is larger than or equal to the first memory capacity in size, the signal storage space is used for storing the process variation generated in processing signals, and the signal storage space is larger than or equal to the second memory capacity in capacity; and the process variation generated in the signal processing is stored and acquired in the signal storage space when the signal processing is performed by the target thread.

Description

technical field [0001] The present invention relates to the field of computers, and more particularly, to methods and devices for signal processing. Background technique [0002] At present, in computer systems, threads need to perform signal processing. For example, when performing fault processing, a monitoring process can be created to monitor the heartbeat of the business process (specifically, the main thread of the business process), and the business process cycle to The monitoring process sends a heartbeat message. When the heartbeat is lost, the monitoring process will restart the business process, or send a signal to the business process to notify it to exit and restart the business process; for another example, start a monitoring thread in the business process. The central processing unit (CPU, Central Processing Unit) occupancy rate of all threads is monitored. When the CPU occupancy rate exceeds the preset threshold, the monitoring thread sends a signal to the bu...
