Problems solved by technology

In this mode, when the virtual machine VM1 is working, other virtual machines cannot work and are in the waiting time
When the time slice is small, the user is less likely to notice the time delay, but if a task of a virtual machine takes up a lot of time (such as figure 1 When the shown VM1), other users will feel the obvious time delay, thus affecting the user experience
[0005] In addition, in the prior art, t

example 2

[0069] exist Figure 5 In the example shown in 7, processing cluster 0 corresponds to virtual function 0, processing cluster 1 corresponds to virtual function 1, processing cluster 2 corresponds to virtual function 0, processing cluster 3 corresponds to virtual function 1, and virtual functions 1 and 2 have equivalent processing power. This example is equivalent to example 3.

example 4

[0071] It can be seen that by mapping different processing clusters to different virtual functions, flexible configuration of virtual functions can be realized, so that the processing capabilities of virtual functions can be dynamically configured according to different requirements. Therefore, compared with the prior art, the technical solution of the present disclosure also has the advantages of simple and flexible configuration.

[0072] According to yet another disclosed embodiment, each virtual function has independent hardware resources.

[0073] The hardware resource mentioned here may be a processing core, or a memory (such as DDR), a bus, a coder / decoder, a video / audio driver, an interface unit, and so on. For example, for PCIe board resources, it includes AI Computing Unit (IPU), Graphics Codec Unit (VPU), Graphics Codec Unit (JPU) and memory. The present disclosure does not impose any limitation on the types of hardware resources.

Abstract

The invention discloses a virtualization method and system based on a multi-core processor, an electronic device and a computing device. The computing device can be included in a combined processing device, and the combined processing device can further comprise a universal interconnection interface and other processing devices. The computing device interacts with other processing devices to jointly complete the computing operation specified by a user. The combined processing device can further comprise a storage device, and the storage device is separately connected with the computing device and the other processing devices and is used for storing the data of the computing device and the other processing devices.

Description

technical field [0001] The present disclosure relates to the field of artificial intelligence, and more specifically, to the virtualization technology of processors. Background technique [0002] In computers, virtualization (Virtualization) is a resource management technology that abstracts and transforms various computer resources, such as servers, networks, memory, and storage, so that users can compare the original configuration A better way to apply these resources. [0003] figure 1 A schematic block diagram of realizing virtualization through time slicing (time slicing) technology is shown. [0004] Such as figure 1 As shown in , there are four virtual machines VM0-VM3, and these virtual machines execute their own tasks respectively. After passing through the time slice manager, these tasks will form time slices and be sorted according to time. The computing engine processes different tasks (time-sharing tasks) according to time slices. In this mode, when the vir...
