Abstract
An apparatus and/or method for generating parity digits of digital information (data) in a digital communication system is disclosed. The communication system (8) is for transferring a plurality of data intervals from an originating data source (12) to a data sink (13). Each data interval comprises one or more blocks of data and each block contains one or more bytes of data. The communication system (8) includes a temporary storage means (24) for holding the data for a limited period. Included are means for transferring (14, 40) one or more data intervals from the data source (12) to the temporary storage means (24) and means for transferring (22, 40) one of the data intervals from the temporary storage means (24) to the data sink (13) including means for calculating (72) error correcting code words associated with each data interval and means for storing (16) the error correcting code words for further processing. A gating means (18, 64) is provided for halting further transfer of the data intervals between the temporary storage means (24) and the data sink (13). The gating means (18, 64) further includes means for sending the stored code words from the means for storing (16) to t…
