J.83 Annex B, Parallel Parity Checksum


This paper proposes a parallel architecture of a parity checksum generator adopted for packet synchronization and error detection in the ITU-T Recommendation J.83 Annex B. The proposed parallel processing architecture removes a performance bottleneck occurred in a conven tional serial processing architecture, leading to signi´Čücant decrease in processing time for generating a parity check sum. The implementation results show that the proposed parallel processing architecture reduces the processing time by 83.1% at the expense of 16% area increase.
