ABSTRACT:
In the system of the present invention, a time critical program operating in a window system environment is implemented. The application program containing time critical procedures is divided functionally into two or more processes. The first process contains all of the CPU time slice sensitive or time critical procedures. This process operates independently of the window system interface and communicates directly with the operating system. The second process implements all procedures which require the user input and output through the window system but not including time critical procedures. This process communicates with and operates through the window system interface. The processes exchange data and synchronize execution through the interprocess communication mechanisms such as shared memory such that the two or more processes operate and appear as a single process to the user while insulating the first process from suspension due to window system operations and blocking procedures.
