The decoding algorithm exploits the symmetric structure of the Viterbi add-compare-select (ACS) operation - commonly known as the ACS butterfly. This shift-register optimization can be found in the well-known text by Dave Forney. Forney, G.D., "The Viterbi Algorithm," Proc. of the IEEE, March 1973. Implementation is non-architecture specific and improves performance on x86 as well as ARM processors. Existing API is unchanged with optimized code being called internally for supported codes.
