RTX是美国Ardence公司开发的基于Windows操作系统的实时解决方案，是目前Windwos平台的唯一纯软件的硬实时扩展子系统。RTX不对Windows系统进行任何封装或修改，其通过在HAL层增加实时HAL扩展来实现基于优先级的抢占式的实时任务的管理和调度。RTX实时子系统RTSS的线程优先于所有Windows线程，提供了对IRQ、I/O、内存的精确直接控制，以确保实时任务的100 可靠性。通过高速的IPC通讯和同步机制，RTX方便地实现与Windows之间的数据交换。RTX的定时器时钟分辨率为100纳秒，最低定时器周期为100微秒。RTX同时支持实时以太网和实时USB通讯。-RTX is the United States Ardence company developed based on the Windows operating system real-time solution, is currently the only pure software Windwos hard real-time expansion subsystem. RTX does not encapsulate or modify any Windows system by implementing real-time HAL extensions at the HAL layer to implement priority-based preemptive real-time task management and scheduling. RTX Real-Time Subsystem The RTSS thread takes precedence over all Windows threads and provides precise direct control of IRQ, I/O, and memory to ensure 100　reliability of real-time tasks. With high-speed IPC communication and synchronization mechanisms, RTX facilitates data exchange with Windows. RTX timer clock resolution of 100 nanoseconds, the minimum timer period of 100 microseconds. RTX supports both real-time Ethernet and real-time USB communication.
