Abstract
In accordance with an embodiment of the present invention, a Viterbi decoder is described that operates on convolutional error correcting codes. The decoder allows for a pipelined architecture and a unique partitioning of survivor memory to maintain data integrity. Throughput rate is improved and stalling minimized by accessing memory words using a look-ahead function to fill the pipeline.
