Multi-processor system and data processing method thereof

Abstract

Provided is a multi-processor system. The multi-processor system comprises an application system, a virtual platform, a virtual hardware system and a hardware forwarding system, wherein one or more applications run on the application system, one or more virtual machines run on the virtual platform, each virtual machine supports operation of a different operating system, and supports operation of one or more applications of the application system, the virtual hardware system comprises a plurality of virtual CPUs, a main core and dedicated memories special for the virtual CPUs, the memories correspond to the virtual CPUs respectively, each virtual CPU is used for supporting operation of each virtual machine, each virtual CPU corresponds to the only virtual ID, a virtual hardware management system runs on the main core, and is used for being in charge of management of all the virtual CPUs, the content of management of all the virtual CPUs includes operation of having control over the number of physical CPUs or physical inner cores in each virtual CPU as needed, the hardware forwarding system is used for receiving messages, searching for forwarding tables, and carrying out processing and forwarding on the messages with corresponding entries according to indication of the entries.

Description

technical field [0001] The present invention relates to the technical field of computer processors, and more specifically, to a multiprocessor system and a data processing method for the multiprocessor system. Background technique [0002] The development of computer processor technology from a single-core CPU (Central Processing Unit, CPU) to a multi-core CPU has greatly improved the processing performance of the CPU. In computer products (such as network communication equipment and application servers, etc.), more and more one or more multi-core CPUs are used to maximize the processing capabilities of the products. [0003] In the prior art, the basic structure of the computer product is as figure 1 As shown, it includes an application system 11, a platform 12 and a hardware forwarding system 13, wherein: the application system 11 is used to run various application programs, such as firewall, content analysis and load balancing, etc.; the hardware forwarding system 13 inc...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventors found that in the above-mentioned computer products, when the platform 12 is based on a multi-CPU or multi-core architecture, each CPU or core can only be fixedly occupied by a certain application program. This fixed binding method exists A serious problem: the utilization rate of the CPU is low, which leads to the reduction of the work efficiency of computer products. At this time, the CPU occupied by applications that do not need to run data will be idle again and cannot be effectively utilized
