Abstract
A decoder for Hamming encoded data in the form of a serial bit stream successive blocks of which are Hamming encoded comprises a serial-to-parallel converter for converting each of the blocks into a plurality of successive parallel bytes, a plurality of parity check circuits for carrying out successive partial parity checks on each of the bytes of a block as each byte is received, and a further plurality of parity check circuits for carrying out parity checks on at least part of successive ones of the bytes as they are received, a parity checker decoder being provided to which the outputs of the parity check circuits are applied for affording an output indicative of possible errors in the block.
