Abstract
The communication overhead in many multiprocessor computing platform is a critical factor over performance. In this paper we present communication performance of a large processing array built with TI 320C40 DSPs. Inter-processor communication is provided by message passing which is a common method used in multiprocessors systems. The system is developed for image processing therefore transmission of large data blocks and various forms of communication are required frequently. The processor used in this system has six built in communication links. They are 8-bit, bi-directional links with a speed of 20 Mbytes/sec. A processing array built with these processors employs MIMD paradigm and static interconnection. In this paper, the communication performance of such DSP network is investigated and performance results are presented. The communication functions include broadcasting, scattering, gathering and point to point transmission of messages.
