Summary:A multi-core processor with a shared physical memory is described. In an embodiment a sending core sends a memory write request to a destination core so that the request may be acted upon by the destination core as if it originated from the destination core. In an example, a data structure is configured in the shared physical memory and mapped to be accessible to the sending and destination cores. In an example, the shared data structure is used as a message channel between the sending and destination cores to carry data using the memory write request. In an embodiment a notification mechanism is enabled using the shared physical memory in order to notify the destination core of events by updating a notification data structure. In an example, the notification mechanism triggers a notification process at the destination core to inform a receiving process of a notification.
