Abstract

The invention provides a parallel computing method and system based on an AMP framework DSP operating system, and a medium. The parallel computing method comprises the following steps: an operating system use step: a hybrid memory mechanism providing step: completing task distribution in a task pool through a shared memory and distributed memory hybrid mechanism according to a used embedded DSP operating system, outputting a distribution task, and synchronizing a task result after task execution is completed; and a task publishing and executing step: publishing and executing the task based onthe multi-core navigation according to the obtained distribution task. According to the invention, an inter-core synchronization, task distribution and recovery mechanism is introduced into the operating system core, so that the scheduling level and frequency of the system are reduced, and the parallel computing efficiency is improved, and the parallel computing method has very important significance for an embedded DSP operating system with very high real-time requirements.

Description

technical field [0001] The present invention relates to the technical field of parallel computing of AMP framework, specifically, relate to the parallel computing method, system and medium based on AMP framework DSP operating system. Background technique [0002] With the rapid development of integrated circuit technology, embedded processors have entered the multi-core era. Multi-core processor operating system can be divided into SMP (Symmetric Multi-Processing) architecture and Asymmetric Multi-processing AMP (Asymmetric Multi-Processing) architecture according to the architecture. In the SMP-based system, all cores of the processor share the system memory and peripheral resources, and the operating system is responsible for inter-processor cooperation and maintains the consistency of the data structure. The hardware resources used are divided, and the cooperation between cores is limited to the use of shared memory. [0003] For mainstream DSP processors, because there...
