Abstract: A neural network device including a convolution static random access memory (SRAM) configured to output a first operation value and a second operation value 1. An accumulation peripheral operator configured to perform an accumulation peripheral operation on the first and the second operation values, a multiplexer array configured to select and output an output value according to a selection signal, a diagonal accumulation SRAM configured to perform a bitwise accumulation of variable weight values and a spatial-wise accumulation operation on an input, a diagonal movement logic, and an addition array operator configured to perform an addition operation of output values of the diagonal movement logic subsequent to a shift operation, the multiplexer array selects any one of an output value of the accumulation peripheral operator and an output value of the addition array operator according to the selection signal and outputs the selected output value to the diagonal accumulation SRAM.
