Abstract
Systems, devices, and methods related to interpolation are provided. An example apparatus includes a slope calculator to calculate a slope value based on a first value and a second value associated with a function. The apparatus further includes a compander to compand the slope value to provide a companded slope value having a smaller bit-width than the calculated slope value. The apparatus further includes a multiplier to multiply the companded slope value by a third value to provide a correction value. The apparatus further includes an adder to add the correction value to the first value or the second value to provide an interpolated value associated with the function. Companding the slope value can reduce a bit-width of the multiplier, and thus may reduce power consumption and/or area.
