description: Goals of the work: 1. Create an isolated real-time subsystem in Windows OS. 2. Provide a real-time system response time of the order of 100 microseconds. To achieve the goals, the following tasks were performed: 1. Conduct a comparative analysis of solutions. 2. Check the possibility of coexistence of a symmetric Windows system and a real-time subsystem on a dedicated core. 3. Create a real-time subsystem in Windows OS. 4. Ensure synchronization of the real-time system and Windows, create a messaging protocol. 5. Conduct an experiment on real equipment, measure the response time. As a result of the work, an isolated real-time subsystem was created on a dedicated core, which coexists with Windows OS on one symmetrical computer. In the course of the work, an experiment was conducted that compared the response time to an external event for a real-time subsystem and a Windows application. It turned out that the response time of the real-time subsystem is about 100 microseconds, and the Windows application is about 500 microseconds. Comparing the results, we can say that the real-time subsystem has achieved its goal: it has expanded the capabilities of the Windows operating system for real-time tasks.
