Abstract
For compressing M-bit data words where M is a plural positive integer, groups of N data words are defined, where N is a plural positive integer, and then the bits of the group of N data words are output as a bit stream including a sequence of sub-streams, each sub-stream relating to a respective bit position in the N data words and being formed from a sequence of N data bits from that bit position of respective data words. The bit sequences are run length encoded and the run length codes thus generated are further encoded using a commaless code such as a Huffman code.
