With a total of 2 patents, his work has had a considerable impact on how device drivers operate within operating systems.
Latest Patents
Wang's latest patents include a user mode device driver interface (UMDDI) that allows a device driver to execute in user-mode while the graphics engine (GRE) remains in kernel-mode. This innovative UMDDI is designed to be implemented in Windows® NT® version 5.0 and similar systems. The UMDDI serves as a layer between the user-mode driver and GRE, encapsulating the user-mode driver and making it appear as a normal kernel-mode driver. It effectively manages kernel-to-user and user-to-kernel transitions, parameter validation, and the management of both kernel-mode and user-mode data and objects. Another patent focuses on translating source code from the user mode device driver to be executed in either kernel mode or user mode, further enhancing the functionality of device drivers.
