Channel decoding of voice and low bit-rate data channels found in third generation (3G) cellular standards requires decoding of convolutional encoded data. The Viterbi-decoder coprocessor 2 (VCP2) provided in the C6474 devices has been designed to perform Viterbi decoding for IS2000 and 3GPP wireless
standards. The VCP2 coprocessor has been designed to perform forward-error correction for 2G and 3G wireless systems. The VCP2 coprocessor offers a very cost effective and synergistic solution when combined with Texas Instruments (TI) DSPs. The VCP2 supports 1941 12.2 Kbps class A 3G voice
channels running at 333 MHz. This document describes the operation and programming of the VCP2. |
