ABSTRACT:
Nonlinear filtering and deblocking applications utilizing SIMD (single instruction multiple data) sign and absolute value operations are disclosed. The method of one embodiment includes receiving first data for a first block and second data for a second block. The first data and said second data include a plurality of rows and columns of pixel data. A block boundary between the first block and the second block is characterized. A correction factor for a deblocking algorithm is calculated with a first instruction for a sign operation that multiplies and with a second instruction for an absolute value operation. Data for pixels located along said block boundary between the first and second black are corrected.
