Parallel and pipeline architectures for 2-D block processing

The authors are concerned with the development and design of parallel and pipeline architectures for 2-D recursive and nonrecursive block digital filters. In this regard, several high-speed structures using single-instruction multiple-data stream (SIMD) machines have been developed. The design of these structures is based on the specific nature of the block convolution processor, block recursive processor, and block state-space processor at both the block and scalar levels. >
