Multi-Tasking Management Based On μC/OS-Ⅱ And Design Of PC Communication Module

Embedded system is a special computer system that fits the strict requirements to application system on functions, cost, size, power consumption and so on. Embedded system is an application-centric and based on computer technology. Its hardware and software can be cut. With the development of computer technology, embedded system has become an important part of the computer field and has become a new research hotspot in recent years. Embedded system has high correlation degree between industries and good market prospects, so develop embedded software will help enhance labor productivity.The software core of embedded system is embedded real-time Operating System (RTOS), the dissertation has an applied research on the features, transplant condition, performance and the principle and process of multi-task scheduling and other aspects ofμC/OS-Ⅱembedded real-time Operating System. It accomplishes multi-task scheduling programming design on hardware platform of MCS 51 and realizes transplantation fromμC/OS-Ⅱto MCS 51.This dissertation also researches the principle of serial communication between PC and ARM core processor S3C44B0 with LabVIEW and accomplishes programming design. Finally, it sums up both achievements and existing problems of the dissertation, and brings up suggestions and prospects for the future wok.
