"OnCore Systems today announced a microkernel that turns Linux into a true real-time operating system. Previously, real-time requests -- those instantly handled by the processor no matter what else was queued -- could only be handled on Linux through heavy customization. But OnCore's software runs underneath Linux, setting memory aside to handle priority requests instantly."
"The reason standard Linux can't do this alone is its level-headed scheduler. The scheduler is the part of the Linux kernel that sends requests -- such as from applications or the operating system -- to the processor. It's fair-share, meaning all requests get equal priority..."
"OnCore's software runs in between the processor and the operating system. It keeps a portion of memory aside, specifically to run real-time requests. But Linux and its associated applications can run as normal -- OnCore's microkernel only kicks in on demand."
