Embodiment Construction

[0040] The basic idea of ​​the present invention is: to provide a real-time communication system based on a virtual machine, aiming at the problem that Windows cannot meet the real-time application requirements, by statically establishing a Windows SMP virtual machine and a real-time virtual communication machine on a multi-core processor, a Windows SMP The virtual machine and the real-time virtual communication machine allocate independent CPU cores, and the method of binding the real-time communication network card to the physical processor core allocated to the real-time virtual communication machine can realize the real-time expansion of Windows that meets the requirements of the application program.

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] figure 1 It is a structural principle diagram of the virtual machine-based real-time communication system of the present invention. The system of t...

Abstract

The invention discloses a real-time communication system based on a virtual machine. The real-time communication system based on the virtual machine comprises a Windows SMP communication virtual machine, virtual machine monitoring software, a physical equipment unit and a real-time communication virtual machine. Specific to the problem that Windows cannot meet the requirement for real-time applications, the method that the Windows SMP virtual machine and the real-time communication virtual machine are established statically on a multi-core processor, independent cores are distributed for the Windows SMP virtual machine and the real-time communication virtual machine, and a real-time communication network card is bound to the physical processor core of the real-time communication virtual machine is adopted, and therefore the requirement for Windows real-time extension of application programs can be met.

Description

technical field [0001] The invention relates to a real-time communication system based on a virtual machine, in particular to building a real-time communication system based on a virtual machine. This technology is suitable for real-time communication requirements in simulation and virtual experiments, and can be widely used in semi-physical simulations and simulations with high real-time requirements. In trial training. Background technique [0002] In the local area network with high-speed Gigabit Ethernet as the communication medium, the first thing to solve the real-time problem of the system is to build a distributed simulation test environment for weapons and equipment based on the Windows operating system. While providing real-time communication capabilities, ensure that Windows uses the rest of the core (core) to perform symmetric multi-processing, that is, supports Windows SMP (Symmetric Multi-Processing, symmetric multi-processing system), which requires providing ...
