Patents by Inventor Dongjiu GENG

Dongjiu GENG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Communication method, apparatus, computer-readable storage medium, and chip
    Patent number: 11941259
    Abstract: A communication method applied to a computer system that includes a first subsystem and a second subsystem. A safety level of the first subsystem is higher than a safety level of the second subsystem. The first subsystem includes a memory access checker. The method includes the memory access checker receives a memory access request from a memory access initiator, determines, based on preconfigured memory safety level division information, whether a safety level of a memory to be accessed by the memory access initiator matches a safety level of the memory access initiator, and allows the memory access initiator to access the memory address when the safety level of the memory matches the safety level of the memory access initiator.

  • Error recovery method and apparatus
    Patent number: 11604711
    Abstract: An error recovery method and apparatus, and a system are disclosed. At least two CPUs in a lockstep mode can exit the lockstep mode when an error occurs in at least one CPU, and the CPU in which the error occurs and a type of the error are determined. When the error can be recovered, the CPU in which the error occurs can be recovered according to a correctly running CPU. This helps the at least two CPUs run again at a position at which a service program is interrupted.
