Short Desc. : Viterbi Dec
Overview :
4i2i's Viterbi FEC core consists of a
convolutional encoder and a Viterbi de-
coder. It supports error correction for
both burst mode and continuous data
input. Convolutional encoding works by
mapping k input bits to n output bits, to
give a rate k
n coded bitstream. At the re-
ceiver, this bitstream is passed through
a maximum-likelihood decoder, the most
popular form of which follows the Viterbi
algorithm. By determining the most
likely original sequence, the decoder can
thus correct errors in the bitstream.
Features : - Convolutional encoder and Viterbi decoder for forward error correction applications
- Supports error correction for both burst mode and continuous data input
- User-configurable parameters such as:
- Selectable code rates 1/3, 1/2, 2/3,3/4, 5/6 or 7/8
- 1-bit hard decision or n-bits soft decision
- Selectable interface widths
- Optional pseudo-BER calculation
- Optional in-phase detection
- Available in VHDL or Verilog source code and Actel-targeted netlist formats
- Convolutional encoder supports Actel's ProASICPLUS, Axcelerator, SX-A/SX, and RTSX-S device families
