Latest Patents

One of his latest patents is titled "Efficient implementation of H.264 4 by 4 intra prediction on a VLIW processor." This invention is instrumental in supporting video compression standards by providing a rich set of intra prediction modes. It introduces a unique table creation and lookup approach to software pipeline the prediction process for all pixels within a block. The table effectively stores constant data and pointer data into a neighbor pixel table, allowing for efficient indexing based on the current intra prediction mode for each pixel of a block. This innovation recalls constant data and other pixel data necessary for calculating an intra prediction value.

Another notable patent is "FIR-based interpolation in advanced video codecs on VLIW processor." This invention classifies a set of all possible half sample and quarter sample pixel value interpolation calculations into various interpolation types. Each function kernel for these interpolation types includes a half sample pixel and all quarter sample pixels, with their value calculations depending on the half sample pixel value. The correct function kernel is invoked to perform the corresponding value interpolation calculation, operating iteratively over multiple macroblocks of at least two macroblock sub-partition sizes. The calculation of dependent quarter sample pixel values utilizes a packed average instruction for optimal performance.
