A Low-Power Dual-VDD Microprocessor for General Purpose Correlation Applications

Overview

This paper presents a 143 MHz 16-bit RISC microprocessor. The processor includes a reconfigurable multiplier that was customized for correlation algorithms. Low-power techniques such as dual-Vdd (2.5/1.8V) and clock gating reduced power by 39% without compromising performance. In addition to the correlator, an I/O interface is included that allows for multichannel interconnect to the external environment.
