Abstract
A component of a computing device, such as the kernel of an operating system, is arranged to identify real time processes running on the device and transparently lock the memory owned by such processes to avoid them being paged out. The kernel is also able to inspect all inter-process communications originated by the real time threads running in such processes, in order to ascertain what other processes they invoke, and, if they have the potential to block a real time operation, the kernel is arranged to lock the areas of memory these processes reference. This procedure operates recursively, and ensures that page faults which might affect the operation of any real time process do not occur.
