Embodiment Construction
[0044] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.
[0045]The traditional all-digital virtual operating environment adopts the virtual technology of the whole hardware system, which does not involve the embedded operating system. When virtualizing the high-speed bus, it is necessary not only to simulate the data transmission function between the processor and the high-speed bus, but also to simulate Synchronization of data transmission between processors, between high-speed buses, between processors and high-speed buses, and more importantly, in the process of data communication between virtual high-speed buses and external stimuli, the timing m...

The invention relates to a method and device for realizing a hybrid simulation all-digital virtual operating environment, which belongs to the field of virtualization technology, and solves the problem that the existing virtual operating environment is complex and time-consuming in the design of a high-speed bus, resulting in low operating efficiency of application programs question. The method includes the following steps: loading the embedded operating system to the software development platform; obtaining a virtualized computing resource center based on the software development platform; modifying the board-level support package information in the embedded operating system so that the embedded operating system can directly access the virtualized computing resource center; The high-speed bus device file at the specified location in the resource center is used to obtain the virtual operating environment, wherein the high-speed bus device file is used for the data communication function of the virtual high-speed bus. The safe operation of the application program in the virtual operating environment is realized, and the operation efficiency of the application program is improved.
Description
technical field [0001] The invention relates to the technical field of virtualization, in particular to a method and device for realizing a mixed simulation all-digital virtual operating environment. Background technique [0002] The traditional all-digital virtual operating environment adopts the virtual technology of the whole hardware system, which not only virtualizes all the core computing units in the hardware system, but also virtualizes all the high-speed buses in the hardware system, but does not involve embedded operations system. On the one hand, as embedded systems increasingly use high-speed real-time buses such as SRIO, 1553B, and LVDS, the virtual complexity of high-speed buses has greatly increased. If the high-speed bus is virtualized in the hardware system, it often exceeds the workload. [0003] On the other hand, when virtualizing a high-speed bus, it is necessary not only to simulate the data transmission function between the processor and each bus, bu...
