32-bit SIMD SHARC architecture for digital audio signal processing applicatisn

摘要

This paper examines desirable DSP architectureal featues to ocnsider for implementaiton of real time audio applciatiosn using a 32-bit Single Instruction Multiple Data (SIMD) DSP based on a Modified Harvard Architecture.This discussion will examine the specific features in this architecture tha tare diesireable for implemmenting many of today's professional and oncsumer audio equipment.The first tpic covered are the imoprtant adio prcessor-specific characterisitcs fo this SIMD architecture such as data word size,dynmaic range/SNR capabiliteis.menmory orgnaizaiton,processor speed,benechamrks and I/O capabilites Part Two will highlight a coule of example DSP audio algorihtms to demonstrater the benefits of such an architectue which cna speed up DSP execution by as much as a factor of 5 over earlier SISD SHARC architectures.
