Abstract

Presented in this paper are fine-grain pipelined architectures for adaptive infinite impulse response (AIIR) filters. The AIIR filters are equation error based. The proposed architectures are developed by employing a combination of scattered look-ahead and relaxed look-ahead pipelining techniques. The scattered look-ahead technique is applied to the non-adaptive (but time-varying) recursive section. The relaxed look-ahead technique is applied to the adaptive blocks. It is shown via simulations that speed-ups of up to 8 and more can be achieved with marginal or no degradation in performance.
