Abstract

A process is provided for operating a computer system (,) having a storage holding an operating system (OS) and an application program (APP.exe) and a third program (VSP Kernel), a first processor (,) having an instruction set, and a second processor (,) having a different instruction set. The process includes a first step of running the first processor (,) to determine whether a part of the application shall be run on the first processor or the second processor and then establishing a second processor object (VSP OBJECT,) if said part shall be run on the second processor and the first processor (,) sending a message that the second processor (,) is to run said at least part of the application program. The third program establishes message handling functions and bus masters data transfer operations for the second processor between the host running the operating system and the second processor running the third program. The process concurrently runs the second processor to perform operations defined by the third program, including to access memory to detect the message that the second processor is to run said at least part of the application program, and runs the second processor (,) to access the second processor object and thereby determine operations for the second processor to access second processor instructions for said part of the application program and data to be processed according to said second processor instructions.
