Abstract:
1. An apparatus comprising: a first circuit configured to calculate and present an output signal having a first resolution and a plurality of output pixels in response to (i) an input signal having a second resolution and a plurality of input pixels and (ii) one or more control signals, wherein said input signal is stored in a register file a scan line at a time in response to a data request signal; and a second circuit configured to generate said control signals in response to (i) a previous calculation by said first circuit and (ii) one or more input parameters, wherein (a) said first circuit is configured to scale and filter said input signal to allow one or more of said input pixels to contribute to the creation of one or more of said output pixels, (b) said apparatus comprises a portion of a block move engine (BME), and (c) said second circuit comprises a coefficient RAM circuit configured to provide (i) a color coefficient for an input color pixel and (ii) an alpha coefficient for an input alpha pixel.
