AXILOG: ABSTRACTIONS FOR APPROXIMATE HARDWARE DESIGN AND REUSE

Abstract

RELAXING THE TRADITIONAL ABSTRACTION OF "NEAR-PERFECT" ACCURACY IN HARDWARE DESIGN CAN YIELD SIGNIFICANT GAINS IN EFFICIENCY, AREA, AND PERFORMANCE. AXILOG, A SET OF LANGUAGE EXTENSIONS FOR VERILOG, PROVIDES THE NECESSARY SYNTAX AND SEMANTICS FOR APPROXIMATE HARDWARE DESIGN AND REUSE, LETTING DESIGNERS SAFELY RELAX ACCURACY REQUIREMENTS IN THE DESIGN WHILE KEEPING THE CRITICAL PARTS STRICTLY PRECISE.
