Design-Space Exploration of Energy-Delay-Area Efficient Coarse-Grain Reconfigurable Datapath

Abstract

This paper presents the VLSI design of a high data throughput, energy and area efficient data path targeted for DSP and multimedia applications. Three different implementations of the reconfigurable data path using static, dynamic domino and D3L logic styles are presented to serve as low power, high speed, and speed-energy optimized variants of the architecture. When implemented using ST Microelectronics 90nm 1V CMOS technology, the proposed data path leads to a maximum supported clock frequency ranging from 917 MHz to 1.2 GHz with a dynamic power consumption @ 500 MHz ranging from 788 µW   to 1.02 mW.
