Abstract

A security bus system based on redundant heterogeneity, including a host access replicator, a system bus, a redundant system bus, and a device access replicator, wherein the host access replicator copies the data request sent by the host, After processing, the requests are respectively sent to the system bus and the redundant system bus; the device access duplicator receives and processes the security data request through the system bus and the redundant system bus respectively. The safety bus system based on redundant heterogeneity of the present invention adopts a simple heterogeneous bus structure to realize system bus interconnection with high diagnostic coverage, which greatly improves the reliability of data transmission between the host computer and the device.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of a system on chip (SoC), and in particular to a virtualized system-on-chip bus. Background technique [0002] The core of the security requirements of the electronic control system is the definition and realization of the system security mechanism. The so-called safety mechanism is a mechanism that detects or controls failures through the functions, components or related technologies of electronic and electrical systems, so that the system can transfer and maintain a safe state. In order to meet the safety requirements of the entire electronic control system, each subsystem needs to complete the definition and realization of its own safety mechanism. [0003] As an important part of the on-chip electronic control system (SoC or microcontroller), the system bus also has its own security requirements, and the definition and implementation of security mechanisms need to be completed...
