Abstract

The invention relates to an inter-core secure communication system for a multi-core heterogeneous domain controller, which comprises a plurality of physical partitions divided according to the type of processors in the multi-core heterogeneous domain controller and a network-on-chip connected with each physical partition; processors of the same type are located in the same physical partition; each processor comprises a processor core and an independent cache unit which are connected with each other; each physical partition further comprises a shared communication bus and a shared memory unit, and the isomorphic processor cores of the processors of the same type in the same physical partition are connected with the shared communication bus through the independent cache units of the processors; the shared communication bus is connected with the shared memory unit, and the shared communication buses in different physical partitions are connected with the network-on-chip. According to the invention, an inter-core communication mechanism between a plurality of isomorphic processor cores and heterogeneous processor cores is established, the transmission quantity of data between the cores and the safety of the data are optimized, and the comprehensive performance of the multi-core heterogeneous domain controller is improved.

Description

technical field [0001] The invention relates to the field of new energy vehicle control, in particular to an inter-core safety communication system of multi-core heterogeneous domain controllers. Background technique [0002] Automated driving, networking, electrification of the power system, and shared mobility are the future development trends of the automotive industry, and these four directions will complement each other. With the rapid penetration of autonomous driving and new energy technologies, the requirements for electronic control and computing power of the whole vehicle have been greatly increased, and the focus of promoting the integration of the whole vehicle has changed from the physical architecture to the high-speed, safe and reliable electronic architecture. The general trend is from Decentralized architecture (third-generation automotive E / E structure with central gateways connecting components) to more centralized systems with dedicated domain controllers...
