  • Patent number: 11194683
    Abstract: The disclosure describes techniques for a self-test of a graphics processing unit (GPU) independent of instructions from another processing device. The GPU may perform the self-test in response to a determination that the GPU enters an idle mode. The self-test may be based on information indicating a safety level, where the safety level indicates how many faults in circuits or memory blocks of the GPU need to be detected.
    Type: Grant

  • Patent number: 7921274
    Abstract: A computer addressing mode and memory access method rely on a memory segment identifier and a memory segment mask for indicating memory locations. In this addressing mode, a processor receives an instruction comprising the memory segment identifier and memory segment mask. The processor employs a two-level address decoding scheme to access individual memory locations. Under this decoding scheme, the processor decodes the memory segment identifier to select a particular memory segment. Each memory segment includes a predefined number of memory locations. The processor selects memory locations within the memory segment based on mask bits set in the memory segment mask. The disclosed addressing mode is advantageous because it allows non-consecutive memory locations to be efficiently accessed.
