ABSTRACT:
Operations for decompression of compressed data is performed in parallel and in a pipelined manner to generate addresses into a memory on-the-fly rather than using a large look-up table. The logic circuits for doing so are thus reduced to the point of being able to be formed by suitable programming of a field programmable gate array (FPGA) while achieving substantial increase in processing speed beyond speed increases attributable to increase of clock rates.
