Abstract
Methods and computer-executable components for real-time scheduling of CPU resources are disclosed. A performance counter determines when to allocate CPU resources to a thread. When it is time to allocate the CPU resources, the performance counter issues a maskable or non-maskable interrupt to an advanced programmable interrupt controller (APIC). The APIC then issues a maskable non-maskable interrupt to the CPU. In response to receiving the non-maskable interrupt, the CPU allocates resources to the thread. In addition, the disclosed methods and computer-executable components also: (a) allow scheduling of CPU resources such that real-time threads are guaranteed respective portions of time slots, (b) enable real-time scheduling on a non-real-time operating system, and (c) provide scheduling of CPU resources on a uni-processor machine such that at least first and second real-time threads dependent on one another are synchronized.
