Improving FPGA Performance for Carry-Save Arithmetic

Paolo Ienne, Philip Brisk, Ajay Kumar Verma, Hadi Parandeh Afshar

The selective use of carry-save arithmetic, where appropriate, can accelerate a variety of arithmetic-dominated circuits. Carry-save arithmetic occurs naturally in a variety of DSP applications, and further opportunities to exploit it can be exposed throug ...

Data-flow transformations to maximize the use of carry-save representation in arithmetic circuits

Paolo Ienne, Philip Brisk, Ajay Kumar Verma

The increasing importance,of datapath circuits in complex systems-on-chip calls for special arithmetic optimizations. The goal is to automatically achieve the handcrafted results which escape classic logic optimizations. Some work has been done in the rece ...

Bio-inspired cellular machines

Fabien Vannel

Information technology has only been around for about fifty years. Although the beginnings of automatic calculation date from as early as the 17th century (W. Schickard built the first mechanical calculator in 1623), it took the invention of the transistor ...

A Low-Jitter and Low-Power CMOS PLL for Clock Multiplication

Pierre-André Farine, Steve Tanner, Michael Ansorge, Kilian Imfeld

this paper describes a phase-locked loop (PLL) designed for clock multiplication in a LVDS transmitter. The PLL consists of a novel low-jitter charge-pump, a fully differential ring-oscillator based VCO, a dynamic-logic PFD, a 2nd order passive loop filter ...
