Abstract
There is provided a system and method in a heterogeneous multiprocessing system for performing external procedure calls from a Client Program to a Server Program, both of which are stored in a common memory. The Client Program is executed by a first CPU under control of a first operating system and the Server Program is executed by a second CPU under control of a second operating system. The first and second operating systems are also stored in the common memory. The Client Program includes a Proxy Procedure for invoking a Server program function, and a Stub Procedure for converting parameter and result data from the first to the second operating system. The Client Program further includes a Protocol Procedure for passing data between the Client and Server CPUs.
