ABSTRACT:
An embodiment of the present invention is a technique to provide a real-time threading service to an application in a multi-core environment. An executive is launched, within a most privilege level of an operating system (OS), on a real-time core in the multi-core environment. The real-time core is sequestered from the OS. A real-time thread is created in a least privilege level on the real-time core for an application using a library. The library is loaded by the application. The real-time thread shares a virtual address space with the application.
