MUSE: a wafer-scale systolic DSP

Abstract

MUSE (Matrix Update Systolic Experiment) is a special-purpose digital signal processor being implemented using restructurable VLSI. It will consist of 5 million working transistors on a single wafer-scale integrated circuit. MUSE is a wafer-scale systolic array designed to operate at the continuous rate of 285 million rotations per second. It will enable space-based radar systems to perform real-time adaptive nulling on up to 63 jammers with nulls of 50 dB. The rotator cell has been fabricated in 2 mu m CMOS; a small testbed for 4 PEs has been built and operates at specification. Design for the wafer-scale interconnect is in progress. MUSE is a 1.7 Billion Real Operations per Second system which fits on a single 4" by 4" silicon substrate.<>
