Abstract
A system is provided for scaling image data comprising a Direct Memory Access (DMA) engine adapted to read the image data from a horizontal pixel strip in a column-by-column format, a scaling block adapted to scale the image data read by the read DMA engine into scaled column output data, and a buffer memory for storing the scaled column output data for the horizontal pixel strip. A method is also provided for scaling an image comprising reading pixel values from a pixel strip in a column-by-column manner across the pixel strip and scaling the pixel values for each column to produce scaled column output data. The scaled column output data for a plurality of columns is then read and the scaled column output data is scaled from the plurality of columns to produce scaled row output data for a row of pixels.
