US Patent 11157593 Apparatus and methods for combining vectors

Aspects for vector combination in neural network are described herein. The aspects may include a direct memory access unit configured to receive aa first vector, a second vector, and a controller vector. The first vector, the second vector, and the controller vector may each include one or more elements indexed in accordance with a same one-dimensional data structure. The aspects may further include a computation module configured to select one of the one or more control values, determine that the selected control value satisfies a predetermined condition, and select one of the one or more first elements that corresponds to the selected control value in the one-dimensional data structure as an output element based on a determination that the selected control value satisfies the predetermined condition.
