Abstract

A method of offloading compilation includes transmitting compilation information from a first subsystem to a second subsystem. The method also includes compiling computer program code into machine-executable code on the second subsystem based on the compilation information received from the first subsystem. The method further includes receiving the machine-executable code from the second subsystem into the first subsystem.
