Abstract: A method for performing a remote procedure call between an application processor and a digital signal processor within a computing device. The computing device may compile interface description language data to generate stub software that executes on the application processor and skel software that executes on the digital signal processor. When an application executing on the application processor invokes a remote procedure call, the application processor may pack argument data within stack memory and transmit an interrupt to the digital signal processor, which may map the physical memory addresses of the argument data into local address space such that no copies of the argument data is made. The digital signal processor may execute skel software that unpacks the argument data and executes a service related to the remote procedure call.
