A Multi-Channel Data Acquisition System Based on DSP

DSP is a kind of microprocessor applied in the processing of real-time digital signal. Compared with the system based on single chip microcomputer,the data acquisition system based on DSP could fairly satisfy the demands of accuracy and real time in data acquisition system. It solves the problem that the speed of data acquisition is too slow to acquire the multi-channel data simultaneously in the data acquisition system. This paper mainly describes the characteristics of CD4060 and TMS302LF2407A,and focuses on the system composition,software design and hardware design of the data acquisition system. This system,taking TMS302LF2407A as the control core,principally completes the fast and accurate acquisition of exterior multi-channel analog signals and realizes the data acquisition and transformation of multi-channel data.
