Abstract
Enabling peripheral device messaging via application portals in processor-based devices is disclosed herein. In one embodiment, a processor-based device comprises a processing element (PE) including an application portal configured to logically operate as a message store, and that is exposed as an application portal address within an address space visible to a peripheral device that is communicatively coupled to the processor-based device. Upon receiving a message directed to the application portal address from the peripheral device, an application portal control circuit enqueues the message in the application portal. In some embodiments, the PE may further provide a dequeue instruction that may be executed as part of the application, and that results in a top element of the application portal being dequeued and transmitted to the application. Some embodiments may provide further mechanisms for sending success and/or failure notifications, and/or for informing the application that the message has been enqueued.
