چکیده
The goal of the research is twofold First, the derivation of a design methodology for FIR filters implementation based on Residue Number System (RNS), aiming at power, delay and hardware complexity reduction comparing with conventional binary implementations. Second, a CAD tool development, which generates synthesizable VHDL description of any RNS system design, in automatic way. This tool can derive RNS Full Adderbased DSP architectures consisting of FIR, Scaling, Converters, Multiplication and Accumulation units.

Moduli Set Selection and Cost Estimation for RNS-Based FIR Filter and Filter Bank Design
Moduli selection is one of the most important issues in the implementation of systems that make use of residue number systems. In this paper, we describe a software tool that assists system designers in moduli selection for the design of RNS-based FIR filters and filter banks. According to some filter specification parameters, the software tool constructs valid moduli sets and calculates their ...
متن کاملDesign and Analysis of RNS Based FIR Filter Using Verilog Language
Digital filter plays an important role in Very Large Scale Integration (VLSI) technology. The existing Finite Impulse Response (FIR) filter has long transient response which is the major limitation. To overcome this drawback, Residue Number System (RNS) based FIR filters is developed which is described in this paper. High-speed is obtained by introducing the residue arithmetic concept that perm...

In this paper, the design of a Finite Impulse Response (FIR) filter based on the residue number system (RNS) is presented. We chose to implement it in the (RNS), because the RNS offers high speed and low power dissipation. This architecture is based on the single RNS multiplier-accumulator (MAC) unit. The three moduli set 1 {2 ,2 ,2 1} n n n + − , which avoids 2 1 n + modulus, is used to design...
