N-WAY FAULT TOLERANT PROCESSING SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18126139 titled 'N-WAY FAULT TOLERANT PROCESSING SYSTEM

The abstract describes a processor with multiple core dies, each associated with a different operating system, producing results that are then compared by a voting circuitry.

• Processor includes multiple core dies with processor cores
• Each core die associated with a different operating system
• Cores execute instructions to produce results
• Results compared by voting circuitry to generate an output

Potential Applications: - High-performance computing - Fault-tolerant systems - Real-time processing applications

Problems Solved: - Efficient utilization of multiple cores - Redundancy for reliability - Seamless integration of different operating systems

Benefits: - Increased processing power - Enhanced system reliability - Flexibility in operating system choices

Commercial Applications: - Data centers - Supercomputers - Embedded systems

Questions about the technology: 1. How does the voting circuitry determine the final output?

  - The voting circuitry compares the results from different core dies and selects the most reliable one based on predefined criteria.

2. What are the advantages of having multiple core dies with different operating systems?

  - Having multiple core dies with different operating systems allows for increased flexibility and fault tolerance in processing tasks.

Original Abstract Submitted

A processor includes two or more core dies each including one or more processor cores. A first core die of the processor is associated with a first operating system and the processor cores of the first core die execute a set of instructions according to the first operating system to produce a first result. A second core of the processor is associated with a second operating system and the processor cores of the second core of the second core die execute the set of instructions according to the second operating system to produce a second result. The first and second core dies provide the first and second results to a voting circuitry that generates an output based on the first and second results.
