ABSTRACT:
A method is disclosed for performing function calls from a first program operating under control of a first operating system running on a first CPU; to a second program operating under control of a second operating system running on a second CPU. The method operates in a heterogeneous multiprocessing system having a common memory accessible by each of the CPU's and disposed for storing the two different operating systems that actively run and control resources of the system. The method begins by initiating the second program. The first program then makes calls to the second program to perform a specific function while passing parameters thereto for processing according to the specific function. The second program processes the parameters according to the function; and, converts the results from a format compatible with the second program to a format compatible with the first program. The second program reactivates the first program for receipt of the results and once received the first program signals the second operating system to terminate operation.
