## Introduction

### Overview

Channel decoding of voice and low bit-rate data channels found in cellular standards such as 2.5G, 3G, and WiMAX requires the decoding of convolutional encoded data. The Viterbi-decoder coprocessor 2 (VCP2) provided in the TCI648x devices performs Viterbi decoding for IS2000 and 3GPP wireless standards. The VCP2 coprocessor also performs 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.
