Abstract
A processing device includes generation circuitry, storage circuitry, and interpolation circuitry. The generation circuitry generates a first index based on a numerical value of a high-order predetermined number of digits. The converted value of the reference input value corresponding to each index obtained in the generation circuitry is beforehand stored as a look-up table in the storage circuitry. The interpolation circuitry acquires the first converted value corresponding to the first index using the look-up table. And the interpolation circuitry computes the second index that adjoins the first index by carrying out increment or decrement of the first index. Furthermore, the interpolation circuitry acquires the second converted value corresponding to the second index using the look-up table of the storage circuitry. And the interpolation circuitry computes the converted value of the input value by linearity interpolation based on the shift amount from the reference input value of the first index.
