This paper examines desirable DSP architectural features to consider for implementation of real time audio applications 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 that are desirable for implementing many of today`s professional and consumer audio equipment. The first topic covered are the important audio processor-specific characteristics of this SIMD architecture such as data word size, dynamic range/SNR capabilities, memory organization, processor speed, benchmarks and I/0 capabilities. Part Two will highlight a couple of example DSP audio algorithms to demonstrate the benefits of such an architecture which can speed up DSP execution by as much as a factor of 5 over earlier SISD SHARC: architectures.
