The present contribution reports the development of an application specific integrated circuit (ASIC) for application in space-borne electronic data handling systems. The function of the ASIC is to perform a two-dimensional, multi-level Discrete Wavelet Transform (DWT) at high data rate. The implemented DWT is detailed mathematically, and the functionality and the architecture of the ASIC are described. The DWT ASIC will perform pixel data decorrelation in the CWIC on-board image compressor.
