摘要： The disclosure describes techniques for interrupt and inter-processor communication (IPC) mechanisms that are shared among computer processors. For example, an artificial reality system includes a plurality of processors; an inter-processor communication (IPC) unit comprising a register, wherein the IPC unit is configured to: receive a memory access request from a first processor of the processors, wherein the memory access request includes information indicative of a hardware identifier (HWID) associated with the first processor; determine whether the HWID associated with the first processor matches an HWID for the register of the IPC unit; and permit, based on determining that the HWID associated with the first processor matches the HWID for the register of the IPC unit, the memory access request to indicate a communication from the first processor to at least one other processor.
