Please help me predict the CPC LABEL for this patentPATENT ABSTRACT: A processor has an instruction fetch unit that fetches ISA instructions from memory and execution units that perform operations on instruction operands to generate results according to the processor's ISA. A hardware neural network unit (NNU) execution unit performs computations associated with artificial neural networks (ANN). The NNU has an array of ALUs, a first memory that holds data words associated with ANN neuron outputs, and a second memory that holds weight words associated with connections between ANN neurons. Each ALU multiplies a portion of the data words by a portion of the weight words to generate products and accumulates the products in an accumulator as an accumulated value. Activation function units normalize the accumulated values to generate outputs associated with ANN neurons. The ISA includes at least one instruction that instructs the processor to write data words and the weight words to the respective first and second memories.
