Abstract
Methods and systems for performing interleaved to planar transformation operations in a mobile terminal having a video display are disclosed. Aspects of one method may include extracting similar color space components from a received block of interleaved YUV color space format video data as data is received, where the block may comprise 128 bits. The similar color space components may be extracted and transferred to a memory, where each type of the similar color space components may be stored contiguously in separate portions of the memory in planar format. The transferring of data may be via direct memory access of 32-bit words. When the line buffer that is receiving the interleaved video data is full, a direct memory access operation may be initiated. Direct memory access operation may also be initiated when the data for a similar color space component for a complete horizontal line is extracted.
