Implementation of embedded system platform based on μC/OS-II and S3C44B0X microprocessor

At present, many of the small and medium-sized enterprises are still using the low-end singlechip to develop products, the completed function is limited and the code is not portability. A new development scheme is transplanting embedded operating system into specific microprocessor to accomplish more powerful functions. μC/OS-II, as a kind of open source code and small real-time operating system, has been widely used in medical treatment, industrial control, testing instruments fields of products development. What´more, S3C44B0X microprocessor performs efficiently and the cost is low. The paper discusses a new method of the transplant and implementation of embedded system platform based on RTOS μC/OS-II and S3C44B0X microprocessor. Transplanted condition and main modules of μC/OS-II are put forward concretely. In addition, key problems confronting in the implementation are discussed and relevant low-level hardware functions which need to be programmed are analyzed in detail. The experimental results verify the stability of the system of the transplantation.
