ABSTRACT:
A run length code decoder, constructed to reduce the number of times of memory access to attain a high speed operation, decodes a run length code such as a modified Huffman code in a facsimile machine. It determines a memory address to be read next from a memory which contains a decode table for the run length code by a result of an arithmetic operation of a predetermined address of the memory, a content at the predetermined address and a next data derived from an input code.
