Abstract

A digital preprocessor for the real-time compression of raw image data is currently under development. Since high input data rates (<EQ 160 Mb/s) have been specified, the processor is being developed fully in hardware. This hardware realization (ALTERA^TM CPLD and space-qualified ASIC technology) implements a compression scheme based on a Discrete Wavelet Transform and a Successive Approximation Quantization coding scheme. Therefore compression can be applied either in fixed rate or in fixed error modes, including a lossless mode.
