Embodiment Construction

[0053] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0054] The structure of the chip involved in this embodiment will be introduced first below.

[0055] The chip in this embodiment has a heterogeneous multi-processor architecture, and each physical processor and the operating system and applications running on it can be called a physical domain. In addition, multiple isolated virtual processor operating environments can also be created through virtualization technology, and each virtual processor and the operating system and application running on it can be called a virtual domain.

[0056] At least one physical domain and at least one virtual domain may be included in the chip. Each physical domain corresponds to a virtual network card, and each virtual domain corr...

Abstract

The invention discloses a hybrid heterogeneous virtualization communication method and a chip, and belongs to the technical field of embedded chips on chips. The method comprises the following steps:allocating a virtual network card to each operating system existing in a chip, and setting a corresponding IP address, so that an application program can achieve cross-operating-system interconnectionand intercommunication in a unified manner (socket) through a routing process of virtual and real gateways. Due to the fact that the application programs can be interconnected and intercommunicated between the physical cores and can also be interconnected and intercommunicated between the physical cores and the virtual machine, the chip is changed into an on-chip distributed system based on network communication logically from an original heterogeneous multi-core processor model. In addition, the method disclosed by the invention can be conveniently expanded to a system-on-chip with more physical cores and virtual machines.

Description

technical field [0001] The embodiments of the present application relate to the field of embedded chip-on-chip technology, and in particular to a hybrid heterogeneous virtualization communication method and a chip. Background technique [0002] Under the development trend of automotive networking and intelligence, chips need to take into account both computing power and functional safety. The main manifestation is that there are usually multiple processors configured in the chip, which requires that the processors not only realize functional isolation, but also retain necessary mutual communication. When communicating between processors, it is necessary to share certain hardware states, transmit data across the network, etc., not only to maintain the independence and security of the respective functions of the processors, but also to reflect the integrity and integrity of the system on chip. [0003] In addition to physically isolating different functional domains in the ch...
