  • Publication number: 20240069098
    Abstract: Disclosed are a fault diagnosis circuit, method and apparatus, and computer readable storage medium. The fault diagnosis circuit includes a safety protection circuit electrically connected to a protected circuit and a diagnosis module electrically connected to the safety protection circuit. The safety protection circuit is configured to perform check operation on stored data in the protected circuit to obtain first check data, perform error injection on second check data corresponding to the stored data, and generate a first check result signal based on the first check data and the second check data after the error injection. The diagnosis module is configured to diagnose faults in the safety protection circuit based on the first check result signal. From embodiments of this disclosure, the safety protection circuit is diagnosed faults through a simple hardware structure, to eliminate the faults based on a diagnosis result, thereby ensuring normal operation of a chip.

  • Publication number: 20240053888
    Abstract: Disclosed are an integrated circuit and processing method for memory access, an electronic device, and a medium. The integrated circuit includes a first and second memory modules, and an access signal determining module respectively connected to the first and second memory modules. The access signal determining module includes: an interface circuit for transmitting a first memory access signal of a processor to the first memory module; an address filtering circuit for determining a target safety level corresponding to an access address of the first memory access signal; and an access signal processing circuit for offsetting the access address of the first memory access signal in response to the target safety level being a preset level, obtaining a second memory access signal based on the offset address, and transmitting the second memory access signal to the second memory module. Thus, a lower-safety-level memory can be accessed by a higher-safety-level function.
