A signal decoding system performs variable length decoding and inverse quantization at high speed. From bit stream temporarily held in a bit string buffer, a bit string is parsed as a table address to look up a lookup table in a table looking-up unit and a table selecting unit. By looking up the table, variable length decoding is performed simultaneously for maximum two codewords. Furthermore, the decoded data is inversely quantized in parallel by using inverse quantizars. The results of inverse quantization are stored at appropriate positions in the block by the block storage unit.
