Communications-processor architecture for point-to-point multiprocessor networks
Point-to-point multiprocessor networks constructed from replicated processing nodes use Very Large Scale Integration (VLSI) technology to achieve high computation rates. Problems are solved by dividing the required computation among nodes in the network. Each node in the system performs communication tasks to transfer messages through the network so that computational tasks at different nodes can share information. It is the node's communication function, not its computational function, that is the focus of this research. The research investigates primitive operations required by communications tasks and a processor architecture that supports the operations. The Communications Processor architecture is proposed for controlling message transfers in point-to-point multiprocessor networks. Novel special purposes structures execute communication operations and allow the CP to achieve high data throughput. The special structures include asynchronous ports that send and receive messages, a switch that connects input and output ports, and an associative lookup table used for routing computations. The special units, plus registers and a general arithmetic logic unit, are integrated with a programmable control mechanism for flexibility so that the CP can be used in different networks.
