Task scheduling method, device and equipment and readable storage medium

Abstract

The invention provides a task scheduling method, device and equipment and a readable storage medium, and the task scheduling method comprises the following steps: when kernel initialization is completed, setting a system clock count value of a kernel, and when the system clock count value of the kernel is zero, starting task scheduling in a first period, and executing a real-time task in a real-time task list; when the number of changes of the system clock count value of the kernel reaches N in one period, executing the non-real-time tasks in the non-real-time task list; when the number of changes of the system clock count value of the kernel reaches M in one period, starting task scheduling of the kernel in the next period. According to the invention, the kernel task scheduling manager of the control system can be compatible with high-real-time application and high-operand tasks so as to adapt to strict real-time application scenes and non-real-time scenes and balance system delay and throughput, and on the basis, ordered execution of each kernel task is realized, and communication among different kernel tasks is simplified.

Description

technical field [0001] The invention relates to the field of automobile controller development, in particular to a task scheduling method, device, equipment and a readable storage medium. Background technique [0002] With the continuous development of the automobile industry, the requirements for information security in existing vehicle driving are constantly increasing, and new driving functions are constantly being introduced, such as new functional requirements for applications related to intelligent driving. In traditional embedded systems, such as gateways, engine controllers, etc., it is necessary to add such applications related to information security and intelligent driving. Because such applications have limited computing requirements for the processor, the original multi-core microprocessor can meet the requirements. required to run. However, the tasks that such applications need to perform, such as the calculation of a large amount of data verification in infor...
