  • Abstract
    To solve recent pressing issues regarding satisfying numerous video codec standards and supporting ldquofull-high-definitionrdquo (full-HD) (i.e., 1920 pixels by 1080 lines) video on different consumer devices, a multi-standard CODEC IP based on a heterogeneous multiprocessor architecture was developed. To achieve satisfactory performance with low power consumption, operation-specific processors were designed in regards to two types of processing: stream processing and pixel processing. The CODEC uses effectively several dedicated circuits for functions which are unsuitable for those processors. To design the CODEC, we developed a C-language model to check that the architecture worked correctly. The model was also used as a reference for verifying the RTL model. The CODEC can process full-HD videos formatted in H.264, MPEG-2, MPEG-4, and VC-1 at an operating frequency of 162 MHz.
