针对多通道CCD图像数据实时记录、预处理问题,本文提出了一种基于DSP并行处理技术的方案.实验结果表明,系统实现了多通道CCD图像数据的实时记录.用四片DSP以及一个通用CPU实现一个最小系统,用于实时记录六路CCD图像数据,同时实现图像数据和辅助数据的分离,处理结果可以记录在本地的磁盘,也可以通过网线完成数据的传输.最小系统安装在标准的CPCI机箱中,当输入通道数大于六路时,可以通过最小系统并行的方式,实现系统的扩展.该方案已经应用于18路CCD图像数据的实时记录系统中,最小系统实现了最高63.2MB/s的数据记录.

In order to solve the real-time record and preprocessing problem of the multi-channel CCD image data,a scheme based on parallel Digital Signal Processing (DSP) technology is proposed,and the realization of the record system are described.The smallest system is mainly composed of four DSP chips and a general CPU,which can be used to record the image data of CCD with 6 channels in real time and separate the image data from the input data.Processing results can be recorded in the local disk or can be transmitted by Ethernet.Two or more systems can parallel process together When the input channels are more than 6 channels.The smallest system can achieve a high speed of 63.2 MB/s.This system has been succeeded in applying to a CCD image data acquisition with 18 channels.
