Abstract:
A convolutional decoder includes a first storage, a second storage, a branch metric processor to determine branch metrics for transitions of states from a start step to a last step according to input bit streams, an ACS processor to select maximum likelihood path metrics to determine a survival path according to the branch metrics and to update states of the start step to the first storage and the second storage alternately based on the selection of the maximum likelihood path metrics, and a trace back logic to selectively trace back the survival path based on the states of the start step stored in a selected storage among the first storage and the second storage.

Claim (Index 11):
A convolutional decoder comprising:\n a path metric memory configured to store first path metrics corresponding to states of a first step; an Add-Compare-Select (ACS) processor configured to, based on first branch metrics and the first path metrics, select second path metrics corresponding to states of a second step; a demultiplexer comprising an input terminal coupled to the ACS processor and output terminals coupled to a first storage and a second storage; a multiplexer comprising input terminals coupled to the first storage and the second storage; and a switch configured to couple an output terminal of the multiplexer to the ACS processor in response to reception of a first selection signal, wherein the ACS processor is further configured to:\n read, via the multiplexer, first states respectively corresponding to the states of the first step from the first storage; and \n write, via the demultiplexer, the read first states to the second storage in response to the second path metrics being selected.
