CWIC on-board image compressor
Christoph H. Schaefer, E. Krahn · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2000
An update of the development status of the CWIC on-board image compressor project is given. For the convenience of the reader, the features of CWIC are recollected: wavelet-based, high-speed, high resolution, constant-rate image compression using space-qualifiable hardware. The compression efficiency of CWIC has been reported earlier but is supplemented with a JPEG comparison presently. The precise real-time performance of CWIC has been obtained from netlist simulation. The CWIC architecture is shown with two interface options: either a parallel or a SpaceWire serial interface. The status of the demonstrator is reported, and the existing filter and coder boards are depicted.
