A Multiprocessor Prototype for Advanced Signal Processing

Abstract

The main goal of this project was to construct a prototype DSP multiprocessing system based on the Texas Instrument TMS320C40 multiprocessing-capable CPUs and show that it provided adequate performance on the Rome Laboratory (RL) Speaker Identification (#Spkrid") code and the Speech Enhancement (#SEU") code. The original proposal called for a 8-CPU prototype and the funded project was for constructing a 4-CPU prototype. The prototype system that was constructed showed that the computational aspects of the Spkrid code and the SEU code can be easily met on the 4-CPU prototype. (At least one additional CPU, not available in the current prototype, is needed for interfacing to the A/D, D/A components.) The bulk of the proposed effort was involved with the parallelization and porting of the supplied code to the target system, and instrumenting the system to get performance measures that will indicate how the system will perform in real-time.
