Abstract:
1. A local System-On-a-Chip (SOC) configured to operate with a remote SOC so as to form a shared memory system having a plurality of memories, said local SOC comprising: a local node controller; and on-chip memory connected to said local node controller; wherein in response to receiving a request from a remote controller of said remote SOC to access a target memory location, said local node controller determines whether said local SOC has exclusive ownership of said target memory location, sends data from said target memory location if said local SOC has exclusive ownership of said target memory location and stores an entry in said on-chip memory that identifies said remote SOC as having generated said request; and wherein an address of said target memory location is part of a shared contiguous global address space that includes memory addresses of memory locations of each memory in said shared memory system.
