Abstract: INTERCONNECT SCHEME FOR SHARED MEMORY LOCAL NETWORKS A plurality of intelligent work stations are provided access to a shared memory through a switching hierachy including a first array of mapping boxes for receiving a first address from an intelligent work station and including a virtual address and offset and for converting the virtual address into a terminal switch port designation and logical address, a first switch for forwarding the logical address and offset to the designated terminal switch port, a second array of mapping boxes for receiving the logical address and offset and for converting the logical address into a memory switch port designation and physical address, and a second switch for forwarding the physical address and offset to the designated memory switch port as an address to the shared memory.
