چکیده

This paper presents an optimized column fast Fourier transform (FFT) architecture, which utilizes bit-serial arithmetic and dynamic reconfiguration to achieve a complete overlap between computation and communication. As a result, for a clock rate of 40 MHz, the system can compute a 24-b precision 1K point complex FFT transform in 9.25 s, far surpassing the performance of any existing FFT systems.

Epoxy-based Flame Retardant Nanocomposite Coatings: Comparison Between Functions of Expandable Graphite and Halloysite Nanotubes

Whis work presents a study on the flammability of epoxy coatings containing two types of nano-scale fillers as potential flame retardants: expandable graphite (EG) and halloysite nanotubes (HNTs). Both nanocomposites are prepared by incorporation of the same amount of nanofiller into the epoxy resin for the sake of comparison. Fire retardant nanocomposite coatings are cured through a two-stage ...

991 International Conference on Parallel Processing B-sys: a 470-processor Programmable Systolic Array

This paper presents an architecture for programmable systolic arrays that provides simple and eecient systolic communication. The Brown Systolic Array is a linear implementation of this Systolic Shared Register architecture; a working 470-processor prototype system performs 108 MOPS. A 32-chip, 1504-processor implementation could provide 5 GOPS of systolic co-processing power on a single board.
