Abstract
An adaptive codebook search (ACS) algorithm is based on a set of matrix operations suitable for data processing engines supporting a single instruction multiple data (SIMD) architecture. The result is a reduction in memory access and increased parallelism to produce an overall improvement in the computational efficiency of ACS processing.
