PROCESSOR-BASED SYSTEM EMPLOYING A SAFETY ISLAND ARCHITECTURE FOR FAIL-SAFE OPERATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240326867 titled 'PROCESSOR-BASED SYSTEM EMPLOYING A SAFETY ISLAND ARCHITECTURE FOR FAIL-SAFE OPERATION

Simplified Explanation

The patent application describes a processor-based system with a safety island architecture for fail-safe operation. The system includes a main domain for controlling a device and a safety island domain with fewer hardware circuits to monitor errors and checkpoint vehicle information.

• The processor-based system employs a safety island architecture for fail-safe operation.
• The main domain controls the device and processes vehicle information from a vehicle network.
• The safety island domain has less hardware circuits and checks vehicle information processed by both domains.
• The safety island domain monitors errors from both the main and safety island domains.

Potential Applications

This technology can be applied in autonomous driving systems, vehicle control systems, and other safety-critical applications where fail-safe operation is crucial.

Problems Solved

The technology addresses the need for reliable fail-safe operation in processor-based systems, especially in high-risk environments like autonomous driving.

Benefits

- Enhanced safety and reliability in vehicle control systems - Improved error monitoring and fault tolerance - Increased confidence in the operation of safety-critical applications

Commercial Applications

Title: Safety Island Processor System for Autonomous Vehicles This technology can be commercially used in autonomous vehicle systems, industrial automation, and other safety-critical applications. It can enhance the safety and reliability of these systems, leading to increased trust and adoption in the market.

Questions about Safety Island Processor System for Fail-Safe Operation

A relevant generic question not answered by the article, with a detailed answer

How does the safety island architecture improve the reliability of processor-based systems? The safety island architecture provides a separate domain with fewer hardware circuits to monitor errors and checkpoint critical information, enhancing fault tolerance and ensuring fail-safe operation in high-risk environments.

Another relevant generic question, with a detailed answer

What are the key differences between the main domain and the safety island domain in the processor-based system? The main domain is responsible for controlling the device and processing vehicle information, while the safety island domain focuses on error monitoring, fault detection, and checkpointing critical data to ensure fail-safe operation.

Original Abstract Submitted

a processor-based system employing a safety island architecture for fail-safe operation and related methods are disclosed. the processor-based system includes a main domain for controlling a device. the main domain receives and processes vehicle information from a vehicle network. the main domain communicates with vehicle modules to control operation of the vehicle. such operation may include different autonomous driving use cases. the processing system includes a safety island domain that includes less hardware circuits as in the main domain. the safety island domain is configured to checkpoint vehicle information processed by both the main and safety island domains and to monitor errors originating in both the main and safety island.
