Abstract
A decoder decodes input codes, such as Modified Huffman, Modified READ, and Modified Modified READ codes, and includes a zero bit detector which detects the number of consecutive leading zero bits of the input code. An address compressor forms address data by performing a logical operation of data indicating the number of detected zero bits and data excluding the consecutive leading zero bits and the next one bit of the data. A reference table for code conversion is addressed by the formed address data from the address compressor and outputs decoded data corresponding to the input code.
