Comparing Software Pipelining for an Operation-Triggered and a Transport-Triggered Architecture

This paper reports the results of a comparison between a new class of architectures, called transport-triggered architectures, and traditional architectures, called operation-t~iggered architectures. It does this comparison by means of the MOVE-i860, which is a transport-triggered approximation of the i860. Several benchmarks are scheduled for the MOVE-i860 by a software pipelining scheduler. By scheduling according to three scheduling disciplines, we are able to measure the advantages of transport-triggered architectures. The results of the experiments show that transport-triggered architectures perform better than operation-triggered architectures with similar hardware.
