Pipeline and Parallel-Pipeline FFT Processors for VLSI Implementations

Abstract: In some signal processing applications, it is desirable to build very high performance fast Fourier transform (FFT) processors. To meet the performance requirements, these processors are typically highly pipelined. Until the advent of VLSI, it was not possible to build a single chip which could be used to construct pipeline FFT processors of a reasonable size. However, VLSI implementations have constraints which differ from those of discrete implementations, requiring another look at some of the typical FFT'algorithms in the light of these constraints.

Very Fast Fourier Transform Algorithms Hardware for Implementation

Abstract: A new method of deriving very fast Fourier transform (FFT) algorithms is described. The resulting algorithms do not employ multiplication and have a form suitable for high performance hardware implementations. The complexity of the algorithms compares favorably to the recent results of Winograd [1].

Reconfigurable Computing: The Theory and Practice of FPGA-Based Computation

Abstract: The main characteristic of Reconfigurable Computing is the presence of hardware that can be reconfigured to implement specific functionality more suitable for specially tailored hardware than on a simple uniprocessor. Reconfigurable computing systems join microprocessors and programmable hardware in order to take advantage of the combined strengths of hardware and software and have been used in applications ranging from embedded systems to high performance computing. Many of the fundamental theories have been identified and used by the Hardware/Software Co-Design research field. Although the same background ideas are shared in both areas, they have different goals and use different approaches.This book is intended as an introduction to the entire range of issues important to reconfigurable computing, using FPGAs as the context, or "computing vehicles" to implement this powerful technology. It will take a reader with a background in the basics of digital design and software programming and provide them with the knowledge needed to be an effective designer or researcher in this rapidly evolving field. · Treatment of FPGAs as computing vehicles rather than glue-logic or ASIC substitutes · Views of FPGA programming beyond Verilog/VHDL · Broad set of case studies demonstrating how to use FPGAs in novel and efficient ways
