A pipelined configurable gate array for embedded processors

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 imple-ment additional reconfigurable pipelined datapaths, suitable for the design of reconfigurable processors. A VLIW recon-figurable processor has been implemented on silicon in a standard 0.18 µm CMOS technology to prove the effective-ness 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%
