Problems solved by technology

Based on the above reasons, the overall design of the application program is more difficult. Since there is no unified multi-core communication framework, the program will not be able to flexibly respond to business changes.
In addition, when the business data changes, the data of inter-core communication will also change, which also makes the communication program non-portable
At present, applications in multi-core processors running in AMP mode realize multi-core communication based on shared memory and inter-core interrupts. However, this method can only meet the basic communication requirements of multi-core communication, and cannot simultaneously realize power secondary Requirements for rapid inter-core deployment of devices and flexible configuration of inter-core communication

Abstract

The invention relates to an inter-core communication method based on a virtual data bus, which is characterized by comprising the following steps of: 1, defining data topology information of inter-core communication based on a multi-core processor, and generating a multi-core resource configuration file according to the data topology information; 2, guiding a main core to analyze the multi-core resource configuration file, and creating a data exchange pipeline in an inter-core shared space of the main core and a plurality of slave cores based on the analysis; and 3, indicating a virtual data bus controller to realize communication interaction of the inter-core communication data based on the data exchange pipeline and the service data type of the inter-core communication. Based on the method provided by the invention, the service data of the inter-core communication can be divided according to types, and the routing table of the inter-core communication is constructed through unified modeling, so that the communication interaction is realized.

Description

technical field [0001] The present invention relates to inter-core communication of multi-core processors, and more specifically, to an inter-core communication method and device based on a virtual data bus. Background technique [0002] At present, with the continuous improvement of CPU performance requirements for various businesses, single-core processors can no longer meet business needs because the high-speed operation of the single-core chip will cause a lot of heat generation and performance degradation. Therefore, multi-core processors are increasingly used in various industries. In the electric power industry, due to the stricter requirements for real-time communication and security during the operation of the power grid, multi-core processors in the electric power industry usually operate in AMP (Asymmetric Multi-processing, asymmetric multi-processing) mode. Moreover, different application programs can run independently among multiple cores, and different applica...
