Multi-channel waveform acquisition system based on digital signal processor

This paper describes the design considerations of multi vhannel high speed waveform acquisition system, which is designed for main drift chamber of BESⅡ. Its high speed data pre processing and data compressing reduces the volume of data transmission. Partial pipelining enables data acquisition and data processing proceed at the same time. This reduces the dead time of the system. To avoid the loss of good events, the pipeline archiecture was used for buffering data. Parallel technique was used in the design of the system in order achieve quicher processing speed.
