At present, Rapid IO has been widely used in embedded platforms due to its high transmission efficiency and low transmission delay, making the software of the embedded platform a new speed. Windows system has the advantages of friendly interface, wide user base, easy maintenance and upgrade, etc., which has received extensive attention in the industry, but the real-time performance is poor and it is impossible to directly communicate with the embedded processor directly through Rapid IO, which makes it impossible to become a semi-physical simulation system. Therefore, the TSI721 driver development based on the RTX environment is designed. The internal structure of Rapid IO protocol, RTX real-time subsystem and Tsi721 switch chip is briefly described. Detailed description of the development framework and interface design of the Tsi721Pcie driver, the main process of RTX driver development. Experiments verify that PCIe and RTX drivers are stable, reliable, and capable of completing tasks in real time.

Abstract
At present, Rapid IO has been widely used in embedded platforms due to its high transmission efficiency and low transmission delay, making the software of the embedded platform a new speed. Windows system has the advantages of friendly interface, wide user base, easy maintenance and upgrade, etc., which has received extensive attention in the industry, but the real-time performance is poor and it is impossible to directly communicate with the embedded processor directly through Rapid IO, which makes it impossible to become a semi-physical simulation system. Therefore, the TSI721 driver development based on the RTX environment is designed. The internal structure of Rapid IO protocol, RTX real-time subsystem and Tsi721 switch chip is briefly described. Detailed description of the development framework and interface design of the Tsi721Pcie driver, the main process of RTX driver development. Experiments verify that PCIe and RTX drivers are stable, reliable, and capable of completing tasks in real time.
