The Design And Implementation Of Data Processing System Based On TMS320F2812

With the development of science and technology ,in various fields, people made ever-increasing demands which about the speed , stability and other real-time performance of data-processing system . In many ways DSP own some powerful advantages. So, it has become one of the best chances in data processing system. Whether the ability of Real-time processing about the external events (interrupt, I / O), or the speed and accuracy of data computing, there is a big advantage of the digital signal processors. This article describes the characteristics of structure and the functions about the most powerful hardware DSP chip-TMS320F2812, and introduce a data-processing system which based on DSP chip, the system which has many characteristics, such as more flexible, easy to configuration and high transmission rate .At first, I'll make a simple overview about the data processing system which I'll built, and then according to the user's needs and the functions which will be to achieved, I completed the design of the system structure and introduced the characteristics of the system. Secondly, introduce the characteristics and the development of DSP, and analysis various parts of the TMS320F2812's structure, functions and principles, and then introduce the features of chip CY7C68001, and the registers' steps of reading and writing. Thirdly, explained the reasons of choose TMS320F2812 chip, and how to use the CCS. This article also focuses on the bus protocol of USB2.0 and its related concepts, describes how to use Driver Studio to prepare and application of the USB device drivers. Proposed and demonstrated of the realization of the program which about the interruption of circuit. Finally, the thesis made the test of the system. The experimental results show that the system meets the design's requirements.
