Abstract

Recently, a new pipelinable PSTAR-RLS algorithm was developed. It was shown to be an effective alternative to the QRD-RLS algorithm when high-speeds are required. Using folding technique, a 4-tap PSTAR-RLS algorithm was implemented on a single VLSI chip. All the operations in the chip are bit-level pipelined. With a 1.2μ CMOS technology this chip is expected to run at 100 MHz. Redundant number system based arithmetic operators were used for performance advantage. Apart from a wafer scale implementation, this is the first ever single chip ASIC implementation of a RLS adaptive filter.
