Title
Simulation and improvement of the processing subsystem of the Manchester dataflow computer
Abstract
The Manchester dataflow computer is a famous dynamic dataflow computer. It is centralized in architecture and simple in organization. Its overhead for communication and scheduling is very small. Its efficiency comes down, when processing elements in the processing subsystem increase. Several articles evaluated its performance and presented improved methods. The authors studied its processing subsystem and carried out the simulation. The simulation results show that the efficiency of the processing subsystem drops dramatically when average instruction execution microcycles become less and the maximum instruction execution rate is nearly attained. Two improved methods are presented to overcome the disadvantage. The improved processing subsystem with a cheap distributor made up of a bus and a two-level fixed priority circuit possesses almost full efficiency no matter whether the average instruction execution microcycles number is large or small and even if the maximum instruction execution rate is approached.
