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.

Abstract: An embodiment of the present invention is a technique to simulate performance of a multi-core system. A micro-architecture effect is estimated from each core in the multi-core system. A model of a memory hierarchy associated with each core is simulated. The simulated model of the memory hierarchy is superpositioned on the estimated micro-architecture effect to produce a performance figure for the multi-core system.

Abstract: A multiple, cooperating operating systems (OS) platform system with multi processors. Multiple operating systems, each of which may be of a different type or nature, can run on different partitions of the multi-processor platform and yet coexist and cooperate. A real time operating system (RTOS) executing on a processor can communicate with another OS executing on another processor via a portion of memory accessible by the RTOS and the OS by perform read and write operations.

Abstract: Embodiments of a multi-processor platform including multiple, cooperating operating systems are described. Multiple operating systems, each of which may be of a different type or nature, run on different partitions of the multi-processor platform, yet coexist and cooperate. In various embodiments, different specialized operating systems, suitable for particular tasks, run on different partitions of the platform. In one embodiment, a host operating system, using a driver, boots and partitions a portion of the platform running other operating systems, and then communicates with, and shares work with, the other operating systems. In one embodiment, the multi-processor platform includes a host operating system and multiple specialized operating systems, such as real-time operating systems, operating alongside the host operating system. Other embodiments are described and claimed.
