Abstract
GENERAL PURPOSE PROCESSOR ARITHMETIC LOGIC UNITS (ALUS) TYPICALLY IMPLEMENT LARGE MICRO-CODED INSTRUCTION SETS TO PROVIDE SYSTEM FLEXIBILITY, WITH THE ULTIMATE GOAL OF SUPPORTING A WIDE BASE OF APPLICATIONS. THE LARGE NUMBER OF INSTRUCTIONS RESULTS IN A COMPLEX, RELATIVELY SLOW CHIP ARCHITECTURE. IN EFFECT, BY BASING THEIR SYSTEMS ON GENERAL PURPOSE ALUS, COMPUTER MANUFACTURERS TRADE-OFF SPEED OF OPERATIONS IN FAVOR OF FLEXIBILITY. HOWEVER, HERE EXIST MANY APPLICATIONS FOR WHICH FLEXIBILITY IS NOT REQUIRED, BUT FOR WHICH SPEED IS THE MAIN GOAL. RISC-BASED SYSTEMS AIM FOR THIS MARKET NICHE. THIS PROPOSAL ADDRESSES THE DEVELOPMENT OF ASP, THE ACCELERATED STRING PROCESSOR. ASP UTILIZES A REDUCED INSTRUCTION SET COMPUTER (RISC) ARCHITECTURE TO PROVIDE PROCESSING OF CHARACTER STRINGS AT RATES IN EXCESS OF 2,000 MCOPS (MILLION CHARACTER OPERATIONS PER SECOND).
