Paper Abstract

This paper presents a motion estimation coprocessor, supporting real-time high definition (HD) video coding. The proposed coprocessor employs a 2D data-reusing processing element array and a multi-standard cost comparator for distortion computation of variable size block. An instruction-set suitable for performing various ME algorithms is developed, providing the flexibility needed for different coding standards and various applications. In 0.13μm CMOS technology, the coprocessor is implemented with 303K gates at operating frequency of 550MHz. A performance comparison to the reference architectures reveals that only the proposed processor can provide the processing capacity for 1920×1080, 60 fps video sequences at 33×33 search window.
