| Outline of Final Research Achievements |
A subtract-multiply operation, (a-b)*c, is a basic and important operation in image processing but it requires much computation time since we first calculate t=(a-b) and, after that, we calculate t*c. In this report, we first show that the subtract-multiply operation can be effectively implemented by “selectors.” After that, we pick up bi-linear interpolation and apply the selector-logics to it. Selector logics can reduce the carry-propagations and then we can realize area-efficient and fast dedicated circuits. We have implemented our proposed bi-linear interpolation circuit in several ways and evaluated each of them.
