Abstract

The invention discloses a contextual information managing method and system. Contextual information is not stored in a stack, but stored in a storage block with a preset size. In addition, the storage block is managed through a linked list mechanism, and the problem that the contextual volume needs to be considered when the task stack volume is allocated by a user. The user allocates the stack volume to tasks only according to the size of temporary data needing to be stored in the executing process of the tasks, and therefore allocation of the task stack volume is more accurate and the risks of stack overflowing when the task stack is used by an operation system are reduced.

Description

technical field [0001] The present application relates to the technical field of embedded systems, in particular to a context information management method and system in a real-time operating system. Background technique [0002] At present, the embedded electronics industry mostly uses an embedded real-time operating system (hereinafter referred to as the operating system) to develop and design embedded controllers for different purposes. The core function of the operating system is task scheduling, which is to manage the state transition and execution sequence of all tasks in the system according to the task priority. When the operating system schedules, all tasks in the ready state at this moment are arbitrated according to the priority, and the task with the highest priority will enter the running state and start executing. The operating system can only have one task running at a time. When the operating system is scheduling, if there are already tasks in the running s...
