Abstract

In recent years the challenge of high performance, low power retargettable embedded system has been faced with different technological and architectural solutions. In this paper we present a new configurable unit explicitly designed to implement additional reconfigurable pipelined datapaths, suitable for the design of reconfigurable processors. A VLIW reconfigurable processor has been implemented on silicon in a standard 0.18 μ m CMOS technology to prove the effectiveness of the proposed unit. Testing on a signal processing algorithms benchmark showed speedups from 4.3x to 13.5x and energy consumption reduction up to 92%.
