DDDP-a Distributed Data Driven Processor

Abstract

This paper describes an architecture of a data flow computer named the Distributed Data Driven Processor (DDDP), and presents an experimental system and the results of experiments using several benchmarks. The experimental system has four processing elements connected by a ring bus, and a structured data memory. The main features of our system are that each processing element is provided with a hardware hashing mechanism to implement token coloring, and a ring bus is used to pass tokens concurrently among processing elements. A hardware monitor was used to measure the performance of the experimental system.
