Abstract: Provided is a neural network accelerator which performs a calculation of a neural network provided with layers, the neural network accelerator including a kernel memory configured to store kernel data related to a filter, a feature map memory configured to store feature map data which are outputs of the layers, and a Processing Element (PE) array including PEs arranged along first and second directions, wherein each of the PEs performs a calculation using the feature map data transmitted in the first direction from the feature map memory and the kernel data transmitted in the second direction from the kernel memory, and transmits a calculation result to the feature map memory in a third direction opposite to the first direction.

Abstract: A processing element and an operating method thereof in a neural network are disclosed. The processing element may include a first multiplexer selecting one of a first value stored in a first memory and a second value stored in a second memory, a second multiplexer selecting one of a first data input signal and an output value of the first multiplexer, a third multiplexer selecting one of the output value of the first multiplexer and a second data input signal, a multiplier multiplying an output value of the second multiplexer by an output value of the third multiplexer, a fourth multiplexer for selecting one of the output value of the second multiplexer and an output value of the multiplier, and a third memory storing an output value of the fourth multiplexer.

Abstract: A reorganizable neural network computing device is provided. The computing device includes a data processing array unit including a plurality of operators disposed at locations corresponding to a row and a column. One or more chaining paths which transfer the first input data from the operator of the first row of the data processing array to the operator of the second row are optionally formed. The plurality of first data input processors of the computing device transfer the first input data for a layer of the neural network to the operators along rows of the data processing array unit, and the plurality of second data input processors of the computing device transfer the second input data to the operators along the columns of the data processing array.
