With lack of real-time support, Windows is not appropriate for test equipments which inevitably require real-time support. Consequently we have no choice to use expensive third-party solutions such as RTX or INtime. In this paper, we design and implement a real-time implanted kernel(RTiK) which support real-time on Windows by using the local APIC of multiprocessor-based x86 architectures. To decrease the interrupt latency, we also use the deferred procedure calls supported by Windows. Finally, we evaluate the performance of the proposed RTiK by measuring real-time capacities of RTiK both on User- and Kernel-levels.
