7.16 Enhanced Viterbi-Decoder Coprocessor (VCP2)

7.16.1 VCP2 Device-Specific Information

The C6474 device has a high-performance embedded coprocessor Viterbi-Decoder Coprocessor (VCP2)
that significantly speeds up channel-decoding operations on-chip. The VCP2 operating at CPU clock
divided-by-3 can decode over 694 7.95-Kbps adaptive multi-rate (AMR)(K = 9, R = 1/3) voice channels.
The VCP2 supports constraint lengths K = 5, 6, 7, 8, and 9, rates R = 3/4, 1/2, 1/3, 1/4, and 1/5, and
flexible polynomials, while generating hard decisions or soft decisions. Communications between the
VCP2 and the CPU are carried out through the EDMA3 controller.

The VCP2 supports:

•

Unlimited frame sizes

•

Code rates 3/4, 1/2, 1/3, 1/4, and 1/5

•

Constraint lengths 5, 6, 7, 8, and 9

•

Programmable encoder polynomials

•

Programmable reliability and convergence lengths

•

Hard and soft decoded decisions

•

Tail and convergent modes

•

Yamamoto logic

•

Tail biting logic

•

Various input and output FIFO lengths

For more detailed information on the VCP2, see the TMS320C6474 DSP Viterbi-Decoder Coprocessor 2
(VCP2) Reference Guide (literature number
