Abstract: A z-first reference neural processing unit (NPU) for mapping Winograd Convolution is disclosed where the NPU includes memory banks configured to store input feature maps (IFMs) in a z-first data storage layout, each of the memory banks being configured to store the IFMs in one of a direct convolution (DConv) mode or a Winograd convolution (WgConv) mode, a reconfigurable IFM distributor configured to receive the IFMs from the memory banks, a parallel reconfigurable Winograd forward transform module configured to receive the IFMs from the reconfigurable IFM distributor and to transform the IFMs in a Winograd domain to transformed IFMs in the WgConv mode, multiply and accumulate (MAC) units configured to perform dot product operations on one of IFMs in the DConv mode and the transformed IFMs in the WgConv mode to obtain intermediate output feature maps (OFMs), and a reconfigurable OFM adder and Winograd inverse transform module configured to generate one of an OFM from the intermediate OFMs in the DConv mode and OFMs from the intermediate OFMs in the WgConv.

Abstract: A method for computing an inner product on a binary data, a ternary data, a non-binary data, and a non-ternary data using an electronic device. The method includes calculating the inner product on a ternary data, designing a fused bitwise data path to support the inner product calculation on the binary data and the ternary data, designing a FPL data path to calculate an inner product between one of the non-binary data and the non-ternary data and one of the binary data and the ternary data, and distributing the inner product calculation for the binary data and the ternary data and the inner product between one of the non-binary data and the non-ternary data and one of the binary data and the ternary data in the fused bitwise data path and the FPL data path.
