Zusammenfassung:A hardware-implemented function evaluator performs mathematical calculations at high speeds to generate data values in place of an LUT. The disclosed embodiments can generate a small number of output values from a large number of input values. The calculations can use functions that are monotonically increasing such as, for example, square root, power curves, and trigonometric functions.
