Abstract

The invention provides a process management method for an embedded system as well as the system. The process management method for the embedded system comprises steps as follows: starting a main management process for monitoring management of processes of the system, starting an auxiliary management process for monitoring management of state information of the system after the main management process is started, and starting other processes in the system by means of the main management process after the auxiliary management process is started. The comprehensiveness of process management of the system is improved, loss of information is avoided, the reliability of the system is improved, the starting correctness of the system is guaranteed, the state information of the system can be managed, exception handling can be performed when necessary, and the system stability is improved.

Description

technical field [0001] The invention belongs to the technical field of computer software and relates to a process management method, in particular to a process management method and system for an embedded system. Background technique [0002] Embedded Linux is a multi-user and multi-tasking operating system. Multi-user means that multiple users can use the same Linux system at the same time; multi-tasking means that multiple tasks can be performed simultaneously under Linux. In more detail, linux adopts a time-sharing management method, all tasks are placed in a queue, and the operating system allocates an appropriate time slice for each task according to the priority of each task, each time slice is very short, The user does not feel that multiple tasks are running, so that all tasks share system resources, so Linux can temporarily suspend a task before it is completed, and then execute another task after a period of time Come back to process this task later, and remove i...
