Abstract

The invention relates to general purpose interprocessor communication implemented through a distributed shared memory network connecting a plurality of processors, computers, multiprocessors, and electronic and optical devices. The invention teaches an apparatus for shared memory based data transfer between a multiplicity of asynchronously operating devices (processors, computers, multiprocessors, etc.) each using possibly distinct memory address translation architectures. The invention further teaches shared virtual memory network communication and administration based on a unique network memory address translation architecture. This architecture is compatible with and augments the address translation and cache block replacement mechanisms of existing devices. More particularly, the invention teaches an adapter card having input/output buffers, page tables and control/status registers for insertion into an operating device, or node, whereby all address translation, memory mapping and packet generation can be implemented. The invention teaches that all network activities can be completed with only write and control operations. An interconnecting switch part and bus arrangement facilitates communication among the network adapters.
