Real-Time Performance Functionality (Windows Embedded CE 6.0)

Windows Embedded CE contains several pieces of functionality that, when combined together, make up the real-time functionality of the OS. It is important to understand how interrupt service routines (ISRs) and interrupt service threads (ISTs) function and interact with the OS to ensure that the OS maintains its real-time performance. In Windows Embedded CE, you can control not only the priority of a thread, but also the amount of time, or quantum, in which threads at the same priority level are allocated each time they are executed. This gives you greater control over when threads are executed in the OS. Windows Embedded CE provides real-time measurement tools that you can use to verify that a specified real-time system can function within the real-time requirements of that OS.
