Abstract
A method and apparatus are described for processing video data. In one embodiment, a processor is provided with a video compression engine (VCE) that has a memory having a plurality of rows and a plurality of columns of addresses. Video data, (luma data or chroma data), is written in row (i.e., raster) order into the addresses of the memory, and then the data is read out of the addresses in column order. Data is written into the addresses of the columns of the memory as they are read out, which is subsequently read out in row order. This process of switching back and forth between reading and writing data in row and column order continues as the data is read and processed by an encoder to generate a compressed video stream.
