Abstract
A method is provided for adding extended functions to a multiprocessor system, specifically, functions that may be called from programming running on a first processor and executed by a second processor. A set of generic entry point commands is provided. Each extended function is associated with an entry point command, that is appropriate for the function's argument format and return requirements, if any. Each entry point command invokes a communications routine that handles the transfer of argument data and return values, if any, between processors.
