High-speed signal processing using systolic arrays over finite rings

This paper presents a simple, modular, architecture for very fast digital signal processing elements. The computation is performed over finite rings (or fields) and is able to emulate processing over the integer ring using residue number systems. The computations are restricted to closed operations (ring or field binary operators) with the ability to perform limited scaling operations. Computat...

A Fast QRNS-Based Algorithm for the DCT and Its Field-Programmable Logic Implementation

This paper assesses the arithmetic benefits provided by the Residue Number System (RNS) for building Digital Signal Processing (DSP) systems with Field Programmable Logic (FPL) technology. The quantifiable benefits of this approach are studied in the context of a new Fast Cosine Transform (FCT) architecture enhanced by using the Quadratic Residue Number System (QRNS). The system reduces the num...

A DCT Architecture based on Complex Residue Number Systems

In this paper a high-performance 1-D DCT processor is shown. It is based on a FFT algorithm that benefits from complex residue arithmetic to reduce the number of operations required. The array is based on the Quadratic Residue Number System (QRNS) which enables the implementation of complex adders (multipliers) with only two modular adders (multipliers). Thus, the number of additions and multip...
