Paper Abstract

The Texas Instruments' TMS320C40 digital signal processor contains communication hardware which enables processors to be connected together to form multiprocessing systems. Analysis of the devices communication channels suggests that it would be beneficial to use additional communication hardware to maximize system performance. The use of mesh routing chips in conjunction with the processors has been investigated. The two devices are interfaced using two TMS320C40 communication channels. Lower message latencies can be achieved by using TMS320C40 communication channels to perform nearest neighbor communications while using the routing chips to perform all other message routing. However, the use of additional TMS320C40 channels can degrade the rate at which packets are injected and consumed from the network, resulting in under utilization of the network bandwidth.
