Abstract
A low cost, high-speed, general-purpose ditigal signal processing system was constructed using the TMS32010 digital signal processor. The system was designed with simplicity, compactness, flexibility and expandibility in mind. A parallel processing architecture was adopted to achieve realtime performance. Four processors were used in the prototype system, but this can be expanded easily. Interprocessor data transfer and communications with the host computer are facilitated via a single common bus and a bank of shared memory. A one-dimensional digital FIR filter and a realtime FFT program were used to evaluate the performance of the system. In addition, a realtime spectrogram was implemented as an application example.
