Performance Comparisons of Modern Digital Signal Processing VLSI Microprocessors F. O. Simons, Jr., and A. L. Robinson High-Performance Computing and Simulation (HCS) Laboratory Electrical Engineering Department Florida A&M University and Florida State University Tallahassee, FL 32316-2175

Abstract - The continual and rapid evolution of modern DSPuP (Digital Signal Processing microProcessors) makes it difficult for experienced DSP analysts to keep up with technological advances. It is even more difficult for new aspiring analysts to enter the DSP field and try to keep up with evolving technologies. Thus, the authors present reviews and performance comparisons of the newest multiprocessor VLSI DSPuP with the intention of providing concise focused analyses that may help established or aspiring DSP analysts evaluate the applicability of new DSP technology to their specific applications. The Analog Devices SHARCTM and the Texas Instruments TMS320C80 families of DSPuPs will be emphasized with some reference to other processors offered where appropriate.

1. Introduction

The combination of continually advancing DSPuP hardware and constantly evolving DSP algorithm development have formed the basis for an exponential growth in successful DSP applications. The market growth for these applications has resulted in the development of new multiprocessor DSPuP VLSI components with very powerful capabilities and complicated operations. It is time consuming for experienced DSP analysts to review and evaluate these new DSPuPs. Aspiring analysts who wish to enter the DSP field would find it even more time consuming, and possibly very difficult to appreciate the significance and opportunities for these new components. Thus, performance comparisons of modern multiprocessor VLSI DSPuPs will be presented in hopes of providing brief time-saving reviews for analysts who need to consider these devices for critical new applications.

The performance comparisons will emphasize the Analog Devices SHARCTM and the Texas Instruments TMS320C80 families. The Motorola DSP96002 and Texas Instruments TMS320C40 will also be considered since the architectures of these microprocessors tend to be well suited for connection with other DSPuPs creating new multiprocessor systems.

Initially, distinguishing architectural features of each of the microprocessors are discussed. Common processor features are then compared and presented in tabular form. The processing speed and power of each of the DSPuPs will then be evaluated in terms of some common digital filtering operations. It should be noted that the digital filtering operations presented were not chosen as a basis for performance criteria because of their implementation and computational complexities. Instead, the operations were chosen due to the fact that they characterize performance criteria common to almost all DSP applications. Finally, evaluations and conclusions relative to performance and applications will be presented.
