  • Publication number: 20230096854
    Abstract: A data processing system includes a controller and a computation device. The controller receives a request for processing a neural network computation from a host, the request including an input feature map and a weight filter. The computation device includes a storage unit allocated to each of integration groups, and performs a convolution operation on the input feature map and the weight filter, sequentially outputs pooling elements as a result of the convolution operation, and performs a pooling operation on the pooling elements. The pooling elements corresponds to each integration group. The computation device performs the pooling operation by integrating a pooling value read from the storage unit and each of the pooling elements into a single value and updating the pooling value stored in the storage unit with a result of the integrating. The integrating and the updating are repeated until all of the pooling elements are integrated.

  • Publication number: 20230043170
    Abstract: A memory device performs a convolution operation. The memory device includes first to N-th processing elements (PEs), a first analog-to-digital converter (ADC), a first shift adder, and a first accumulator. The first to N-th PEs, where N is a natural number equal to or greater than 2, are respectively associated with at least one weight data included in a weight feature map and are configured to perform a partial convolution operation with at least one input data included in an input feature map. The first ADC is configured to receive a first partial convolution operation result from the first to N-th PEs. The first shift adder shifts an output of the first ADC. The first accumulator accumulates an output from the first shift adder.

  • Publication number: 20230040775
    Abstract: A semiconductor memory apparatus may include: a data adjusting circuit configured to conditionally adjust a weight data value for a MAC (Multiplication and ACcumulation) operation based on comparing the weight data value to a reference data value, and generate flag information indicating whether the weight data value has been adjusted; a memory cell array circuit configured to store the adjusted weight data value outputted from the data adjusting circuit; and a data calculation circuit configured to recover, on the flag information, a result based on the weight data value from a result based on the adjusted weight data value to perform the MAC operation on an input data value and the weight data value.
