Abstract: A data processing system includes a buffer, a design under checking (DUC), and a self-checking circuit. The buffer is used to buffer data generated from a source device. The DUC is used to perform a designated function upon data read from the buffer when operating under a normal mode. The self-checking circuit is used to apply logic functional checking to the DUC when the DUC operates under a self-checking mode. When the DUC operates under the self-checking mode, the buffer keeps buffering data generated from the source device.

Abstract: A method and apparatus for deblocking process using multiple processing units are disclosed. The video image is divided into at least two regions. The in-loop filter is applied to block boundaries associated with said at least two regions using multiple processing units. The in-loop filter is re-applied to one or more second block boundaries adjacent to region edge between two regions after applying the in-loop filter to the first block boundaries adjacent to the region edge. Furthermore, at least a first portion of said applying the in-loop filter to the first block boundaries and a second portion of said applying the in-loop filter to the second block boundaries are performed concurrently. The multiple processing units may correspond to multiple processing cores within one processor chip.

Abstract translation: 公开了一种使用多个处理单元去块处理的方法和装置。 视频图像被分成至少两个区域。 使用多个处理单元将环路滤波器应用于与所述至少两个区域相关联的块边界。 在将环路滤波器应用于与区域边缘相邻的第一块边界之后，将环路滤波器重新应用于与两个区域之间的区域边缘相邻的一个或多个第二块边界。 此外，同时执行将所述环路滤波器应用于所述第一块边界的所述至少第一部分和将所述环路滤波器应用于所述第二块边界的第二部分。 多个处理单元可以对应于一个处理器芯片内的多个处理核心。
