Abstract
A conversion apparatus that converts and adapts standard processor bus protocol and architecture, such as the MicroChannel (IBM Trademark) bus, to more progressive switch interconnection protocol and architecture. Existing bus-based architecture is extended to perform parallel and clustering functions by enabling the interconnection of thousands of processors. A conversion apparatus controls the transfer of data messages from one nodal element across a switch network to another nodal element by using direct memory access capabilities controlled by intelligent bus masters. This approach does not require interactive support from the processor at either nodal element during the message transmission, and frees up both processors to perform other tasks. The communication media is switch-based and is fully parallel, supporting n transmissions simultaneously, where n is the number of nodes interconnected by the switching network.
