Systolic architectures for vector quantization
Grant A. Davidson, Peter R. Cappello, A. Gersho · IEEE Transactions on Acoustics Speech and Signal Processing · 1988
A family of architectural techniques are proposed which offer efficient computation of weighted Euclidean distance measures for nearest-neighbor codebook searching. The general approach uses a single metric comparator chip in conjunction with a linear array of inner product processor chips. Very high vector-quantization (VQ) throughout can be achieved for many speech and image-processing applications. Several alternative configurations allow reasonable tradeoffs between speed and VLSI chip area required.>
