Task processing method, task processor, and task processing device

Abstract

The present application provides a task processing method, a task processor, and a task processing apparatus for prioritizing the execution of high-priority tasks, thereby satisfying the Qos requirements of high-priority tasks. A method for an embodiment of that present application include obtaining a task to be perform; Determining a first priority of tasks to be performed; Determining a target set of logical operation units from at least one set of logical operation units according to a first priority, the target set of logical operation units comprising at least one logical operation unit,a logical operation unit for executing a task to be executed; When the target logical operation unit set has the current task, the task to be executed and the task with the highest priority among thecurrent tasks are preferentially executed.

Description

technical field [0001] The present application relates to the field of computers, in particular to a task processing method, a task processor and a task processing device. Background technique [0002] With the continuous improvement of users' requirements on processor performance, the problem of power consumption limits the development of single-core processors to continuously improve performance, and more and more multi-core processors have emerged as the times require. In a multi-core processor, multiple processors compute in parallel, and the business tasks to be processed are decomposed into several parts. According to certain scheduling principles, each part is scheduled to be executed on a core by the functional module responsible for scheduling. [0003] Based on the multi-core parallel computing architecture, the centralized scheduling function module or scheduling core is responsible for the scheduling and allocation of tasks. Due to the diversity of services, diff...

Problems solved by technology

[0004] However, the target core is generally based on the first-come-first-served Run to Completion method. Even if the task scheduled later has a high priority, it must wait for the low-priority task scheduled earlier to complete before it can be executed. In a real-time system, the task execution time is extremely demanding. Strict, especially in wireless communication systems, the processing time of a task is only about tens of microseconds, the real-time performance of tasks based on Runto Completion is poor, and the quality of service (Quality of Service, Qos) requirements of high-priority tasks are difficult to guarantee
