摘要
采用RISC单片机和DPRAM作为关键器件，设计了光学Hadamard编码成像的解码系统，完成了实时解码。解码系统不仅具有很高的处理速度和精度，而且还具有小型化、低功耗的特点。图像分辨率为4095（65×63）像素，解码速度为23．92帧/s，运算误差小于1／2LSB.
It is described a RISC single-chip micro-processor and a dual-port RAM applied to the design of a real time decoding module of Hadamard transform imager with high processing speed and precision as well as small size and power supply. Performance data abtained from an experimental imaging system are given in this paper as that number of picture element = 4095(65×63 ), frame rate ＝ 23. 92 frame/s, decoding accuracy ＞1/2 LSB.
