Abstract

The invention relates to a multi-DSP (Digital Signal Processor) platform based distributed type real-time multiple task operating system and belongs to the field of an embedded operation system. The system is characterized by being a distributed type real-time operating system which is capable of performing real-time scheduling on multiple embedded processing modules on each DSP processor of the multi-DSP platform. The system is provided with a storage management module, a task communication module and a task scheduling module, wherein the storage management module is used for storing and managing each input task and each output task; the task communication module is used for internally and externally communicating with a main control computer or the embedded task scheduling module and inputting a to-be-processed task or outputting a processed task; the task scheduling module is used for dynamically dividing the to-be-processed task from the task communication module into a waiting state task, a ready state task and an output state task according to the real-time state of the task; and the task is scanned in turn according to a task processing process, so as to finish a conversion process of waiting-ready and ready-outputting task real-time state. The system provided by the invention can be used for simultaneously performing real-time scheduling on each task module, ensuring the finishing of the processing task and outputting at each processing node of the multi-DSP platform.

Description

technical field [0001] The invention belongs to the field of embedded operating systems, in particular to a distributed real-time multi-task operating system based on a multi-DSP processor platform. Background technique [0002] With the development of today's DSP technology, DSP is more and more used in consumer electronics, communications, military and other fields. The software development based on DSP system has gone through two stages: no operating system development and operating system-based development. In the development stage without an operating system, the system does not have the support of an operating system, and the underlying hardware resources are usually accessed through assembly language. Such systems generally have single functions, strong pertinence, and no user interface. In the development stage with an operating system, the system can support multitasking, and has functions such as communication management, memory management, and scheduling manageme...
