摘要
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.
