  • Publication number: 20220342736
    Abstract: A data processing circuit and a fault-mitigating method are provided. In the method, multiple sub-sequences are divided from sequence data. A first sub-sequence of the sub-sequences is accessed from a memory for a multiply-accumulate (MAC) operation to obtain a first computed result. The MAC operation is performed on a second sub-sequence of the sub-sequences in the memory to obtain a second computed result. The first and the second computed results are combined, where the combined result of the first and the second computed results is related to the result of the MAC operation on the sequence data directly. Accordingly, the error rate could be reduced, so as to mitigate fault.

  • Patent number: 11461204
    Abstract: A data processing circuit and a fault-mitigating method, which are adapted for a memory having a faulty bit, are provided. The memory is configured to store data related to an image, a weight for a multiply-accumulate (MAC) operation of image feature extraction, and/or a value for an activation operation. Sequence data is written into the memory. The bit number of the sequence data equals to the bit number used for storing data in a sequence block of the memory. The sequence data is accessed from the memory, wherein the access of the faulty bit in the memory is ignored. The value of the faulty bit is replaced by the value of a non-faulty bit in the memory to form new sequence data. The new sequence data is used for MAC. Accordingly, the accuracy of image recognition can be improved for the faulty memory.
