(English Abstract) |
In this paper, we present a design of MPEG-4 video codec chip to reduce the power consumption and the external memory bandwidth accessing with mixed motion estimation algorithm and its implementation. This method comprised first and second units. The first search is conducted with a motion estimation skip, which is motion vector prediction and motion compensation with previous parameters. In all test sequence performed, this reduced computation load to 32% that of conventional two-step methods with respect to that of a MPEG models. This chip contains 388,885 gates, 662k bits memory, and the chip size was 9.7 mm x 9.7 mm which was fabricated using 0.35 micron 4-layers metal CMOS technology.
