Abstract
Code compression is known as an effective technique to reduce instruction memory size on an embedded system. However, code compression can also be very effective in increasing the processor-to-memory bandwidth and hence provide increased system performance. A code decompression engine having plurality of dictionary tables, coupled with decoding circuitry and appropriate control circuitry, is coupled between the processor core and the instruction cache. The code decompression engine provides one-cycle decompression of compressed instructions that are intermixed with uncompressed instructions, thereby increasing processor-to-memory bandwidth and avoiding processor stalls.
