Memory Reservation System in Real-Time Mach

This paper proposes a virtual memory management system suitable for interactive continuous media applications. Our virtual memory management system enables continuous media applications to reserve physical memory for allocating pages as soon as possible when the applications require the pages. The system implicitly and incrementally allocates and wires pages used for processing timing critical media data. Also, our system supports applications that adapt the amount of wired memory to the memory usages of other continuous media applications. 1 Introduction Operating system supports for continuous media applications are one of the most exciting topics in operating system researches. Continuous media applications such as multimedia conference systems and video ondemand systems that play audio and video data must satisfy their timing constraint requirements. Real-time techniques are attractive since the correctness of continuous media processing depends on whether timing constraints of r..
