Latest Patents

Tu-Chih Wang holds a patent for an "Architecture and method for parallel embedded block coding." This invention provides a high-speed, memory-efficient parallel coding technique for embedded block coding with optimized truncation (EBCOT). The method processes a discrete wavelet transform (DWT) coefficient at a clock cycle without the need for storing any state variable. This innovation reduces the requirement for state variable memory and minimizes external memory bandwidth. With the same chip-area cost and lower power consumption, the processing rate of this invention is several times higher than conventional schemes. It can process 50 million coefficients per second at 100 MHz and encode lossless HDTV 720p resolution pictures at 30 frames per second in real time.
