  • Isolating a region of a system on a chip for safety critical operations
    Patent number: 11803668
    Abstract: In various examples, an integrated circuit includes first and second portions operating within separate domains. The second portion has an interface that connects the first and second portions. The second portion selectively locks the interface to prevent communication with the first portion over the interface, and selectively unlocks the interface to allow communication with the first portion over the interface.
    Type: Grant

  • Transmitting data between regions of varying safety integrity levels in a system on a chip
    Patent number: 11573856
    Abstract: In various examples, a system includes a memory operating within a first risk level and circuitry operating within a second risk level that indicates more risk than the first risk level. The circuitry reads and/or writes data to a first memory address within the memory, and reads and/or writes an error detection code to a second memory address within the memory.
