Abstract
A method and apparatus for hardware-based anamorphic video scaling. In one embodiment, the method includes the fetch of zero or more new input pixels according to an entry of an input control memory corresponding to a current output pixel. Once fetched, the zero or more new input pixels replace at least one stored input pixel of N, input pixels. Using the updated N, input pixels and an N, coefficient set selected according to an entry of a coefficient memory corresponding to the current output pixel, a pixel computation, such as, for example, an anamorphic scaling computation, is performed. In one embodiment, the anamorphic scaling is performed by subdividing an X×Y pixel frame into X/M M×Y pixel subframes. Other embodiments are described and claimed.
