• This paper presents a method to improve implementation accuracy of a recently proposed CORDIC ARMA lattice filter. Since the CORDIC ARMA lattice filter algorithm has a problem in its shift sequence, it cannot implement a lattice filter accurately. Therefore, in this paper we apply the shift sequence proposed by Walther without problem to the CORDIC ARMA lattice filter, and then we realize an accurate lattice filter. In addition, we propose a new pipelined architecture for the CORDIC ARMA lattice filter. The proposed lattice filter architecture consists of CORDIC processors implemented in the pipelined fashion; it can achieve a high data processing throughput rate.
