Patent number: 11977432Abstract: 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.Type: GrantFiled: October 25, 2021Date of Patent: May 7, 2024Assignee: Skymizer Taiwan Inc.Inventors: Shu-Ming Liu, Jen-ho Kuo, Wen Li Tang, Kai-Chiang Wu

Patent number: 11978526Abstract: A data processing circuit and a fault mitigating method are provided. The method is adapted for a memory having at least one fault bit. The memory provides a block for data storage. A difference between an output of a value of a plurality of bits input to at least one computing layer in a neural network and a correct value is determined. The bits are respectively considered the at least one fault bit. A repair condition is determined based on the difference. The repair condition includes a correspondence between a position where the fault bit is located in the block and at least one non-fault bit in the memory. A value of at least one non-fault bit of the memory replaces a value of the fault bit based on the repair condition.Type: GrantFiled: March 28, 2022Date of Patent: May 7, 2024Assignee: Skymizer Taiwan Inc.Inventors: Shu-Ming Liu, Kai-Chiang Wu, Chien-Fa Chen, Wen Li Tang
