EXECUTABLE PASSING USING MAILBOX REGISTERS

Abstract

A mailbox register is provided in local memory of a processor device, the processor device connected to a host processor device by an interconnect. The processor device accesses the mailbox register to determine that a ready value in the mailbox register identifies that an executable has been written to the mailbox register by the host processor device. The processor device reads the executable from the mailbox register and executes the executable to generate a result. The processor device writes an execution finished value to the mailbox register based on execution of the executable by the processor circuitry, which the host processor device can read to identify that execution of the executable is complete.
