Design and Development of ECG Monitor's Software System Based on µC/OS-II

【Abstract】µC/OS-II is a stable, real-time and code-efficient operating system kernel. This paper introduces the design and implementation of an ECG monitor’s embedded software system based on µC/OS-II. The developer transplants it to the S3C2410 processor, configures it to fit this system, and creates and runs 8 tasks on this system. They communicate with each other by several message queues. It also compares and discusses the advantage and disadvantage among the systems which are without OS but with Linux and µC/OS-II. The monitor receives a high praise from cardiologists and patients. It will have a broad application anticipation. 【Key words】µC/OS-II; ECG monitor; ARM
