摘要

Windows NT是商业领域的主要操作系统，据说通过支持固定优先级调度而具有实时性。然而，即使使用最高的系统优先级，也不能保证应用程序的实时能力。一些厂商已经通过修改硬件抽象层(HAL)和内核来解决这个问题，但这将失去Windows NT的标准化。实时PC是在Windows NT中作为设备驱动程序实现的实时任务调度程序，通过使用实时PC，用户可以在Windows NT上创建必须以毫秒为周期执行的实时任务。实时PC也在Windows CE上实现，并且实时任务可以在两个平台上执行。

Real-time extension for Windows NT/CE used for control systems

Windows NT is a major operating system in business area and is said to have real-time capability by supporting the fixed priority scheduling. However, even if the highest system priority is used, real-time capability for applications are not guaranteed. Some vendors have accomplished this problem by modifying the hardware abstraction layer (HAL) and the kernel but this will lose the standardization of Windows NT. In this paper, we propose Real-time PC. Real-time PC is a real-time task scheduler which is implemented as a device driver in Windows NT, and by using Real-time PC, users are able to create real-time tasks that have to be executed periodically on a millisecond base on Windows NT. Real-time PC is also implemented on Windows CE, and the real-time tasks can be executed on either platform.
