Abstract

An activation accelerator for a neural network accelerator includes a look-up table that stores a plurality of values representing a non-linear activation function, and activation pipelines. Each activation pipeline comprises a range conversion unit that receives an input value and generates a converted value from the input value, an index generation unit that generates an index and an interpolation value from the converted value, a look-up table interface unit that retrieves multiple values from the look-up table based on the index, and an interpolation unit that receives information identifying a rounding mode of a plurality of rounding modes, and generates an estimate of a result of the non-linear activation function for the input value from an interpolation output generated by interpolating between the multiple values retrieved from the look-up table using the interpolation value and rounding in accordance with the identified rounding mode.
