| description | The structure of a computer which utilizes a data-flow program representation as its base language is described. The use of the data-flow representation allows full exploitation by the processor of the parallelism and concurrency achievable through the data-flow form. The unique architecture of the processor avoids the usual problems of processor switching and memory/processor interconnection by the use of interconnection networks which has a great deal of inherent parallelism. The structure of the processor allows a large number of instructions to be active simultaneously. These active instructions pass through the interconnection networks concurrently and form streams of instructions for the pipelined functional units. Due to the cyclic nature of an iterative computation, the possiblity of deadlock can arise in the performance of such a computation within the data-flow architecture. A deadlock is caused by the interaction of several simultaneously active cycles of the same iterative computation. The use of a recursive rather than iterative representation of a computation avoids the deadlock problem and provides a more efficient implementation of the computation within the architecture. For this reason, a program executed by the data-flow processor is restricted to an acyclic directed graph representation. |
