The Research Of Embedded System Based On DSP

Embedded system is taking more and more important roles in information industry with the feature of high integration, high performance, high speed, low power and stability. Now it is a new hotpot in the industry. This thesis gave a brief introduction to the character of Embedded System, its basic theory and some of important concepts. Introduced a RTOS μC/OS-Ⅱ. The kernel mechanism, the core data structure and API is deeper analyzed. Today DSP has become the foundation of digital industry. This thesis gave a simple study on the architecture, instruction set and development tool of DSP, while the TI TMS320C54xx is specially introduced in detail. uC/OS-Ⅱ was successful transplanted to TMS320C54xx, and some embedded system blocks were built based on it. Finally a basic embedded system development platform based on DSP with uC/OS-Ⅱ kernel is built. The software development of DSP system has become a choke point, due to the complexity of the real-time DSP system. In this paper, this problem has been well solved by using μC/OS-Ⅱ kernel with a low system cost.
