A parallel computer for digital signal processing

摘要

The communication and synchronization schemes for a distributed memory parallel computer are studied. The main goal of this work is to develop tools to control the processes and the broadcasting of data over a parallel computer developed with Texas Instruments TMS320C40 processors. These tools must remain simple, fast and efficient to permit good speed improvement over a uniprocessor system of the same type. Digital signal processing algorithms have been used to test the functionality and the speed of these tools. Good results have been observed with a fast Fourier transform and a Viterbi decoder.
