Claim 14:
15. A neural network system, comprising:
an activation function processing unit implemented using one or more hardware processors and a memory configured to:
receive a first input value of a first activation function and determine a function value of the first activation function corresponding to the first input value based on a shared lookup table including a plurality of function values of the first activation function,
wherein the shared lookup table includes at least a plurality of function values of a Sigmoid function or of a Hyperbolic tangent function; and
receive a second input value of a second activation function and determine a function value of the second activation function corresponding to the second input value based on one of the plurality of function values of the first activation function in the shared lookup table, the first and second activation functions being different functions.
