VLSI Modular architectures for complex digital signal processing applications

Recently, the Quadratic Residue Number System (QRNS)[3,4] and Modified Quadratic Residue Number System (MQRNS)[1,2] have been introduced to perform complex multiplications efficiently. The growing number of complex digital signal processing applications will be implemented more efficiently and economically by using Very Large Scale Integration (VLSI) technology. In this paper we discuss VLSI implementation of complex multiplication using the QRNS and MQRNS. We also concentrate on the aspects of VLSI implementation of Finite Impulse Response (FIR) filter architectures.
