The design of VLSI parallel processors requires a fundamental understanding of the parallel computing algorithm and an appreciation of the implementational constraint on communications. Based on such consideration, this paper develops a highly concurrent Toeplitz system solver, featuring maximum parallelism and localized communication. More precisely, a highly parallel algorithm is proposed which achieves O(N) computing time with a linear array of O(N) processors. This compares very favorably to the O(N log2N) computing time attainable with the traditional Levinson algorithm implemented in parallel. Furthermore, to comply with the communication constraint, a pipelined processor architecture is proposed which uses only localized interconnections and yet retains the maximum parallelism attainable.
