Abstract

In this paper, the matrix lookahead transformation is developed to achieve fine-grain pipelining for Cordic based QRD-RLS adaptive filtering algorithm. Various implementation styles are proposed. They include pipelining, block processing, and incremental block processing. The proposed architectures can operate at arbitrarily high sample rates, and consist of only Givens and a few Gaussian rotations which can be mapped onto a Cordic based Jacobi specific dataflow processor.
