In recent years, the rapidly developing technology of CPLD/FPGA has been one of important technology of digital signal processing. In this paper what is mainly discussed is the hardware implementation of the two application specific information processing modules by CPLD or FPGA, which are S+P inverse transformation, the inverse transform module of an image compressing system, and 4096-point complex FFT/IFFT module, the central module of the digital pulse compressing system. In the former, firstly the related knowledge of S+P inverse transform is presented. Easy in implementation, good in storage space, such transform is the base of an image coding algorithm image compressing system. Secondly, the hardware implementation based on CPLD of the S+P inverse transformation is shown. In the latter, firstly the fact that digital pulse compressing technology is one of the most important ways of signal processing in modern radar is introduced. The module of 4096-point complex FFT/IFFT play a very important role in hardware implementation of digital pulse compressing system. Secondly the basic theory of Radix-4 FFT and the hardware implementation based on FPGA of the 4096-point complex FFT/IFFT is illustrated in detail.
