    • An embodiment of the present invention is an apparatus to filter two-dimensional (2-D) data. A first filter processes two-dimensional (2-D) data in a block of pixels in a first dimension for a plurality of filter sizes. The block has a swath. A register file stores the 2-D data based on programmable information. A second filter filters the stored 2-D data in a second dimension to generate filter outputs in one of static and dynamic modes based on the programmable information. The static mode leaves the filter outputs fixed for the swath and the dynamic mode selects the filter outputs on a pixel basis. The filter outputs include first and second filter outputs.
    • 本发明的实施例是用于过滤二维(2-D)数据的装置。 第一滤波器处理多个滤波器尺寸的第一维中的像素块中的二维(2-D)数据。 块有一条线。 寄存器文件基于可编程信息存储2-D数据。 第二个滤波器在第二维中对存储的2-D数据进行滤波,以基于可编程信息在静态和动态模式之一中产生滤波器输出。 静态模式使滤波器输出固定为条带,动态模式以像素为单位选择滤波器输出。 滤波器输出包括第一和第二滤波器输出。

    • In one embodiment, a method and apparatus for filtering input pixel data is configurable to perform a one-dimensional or two-dimensional filtering process. Further, in one embodiment, the two-dimensional filter can be configured to perform a separable or non-separable filter. The type of filter can be configured, along with the size of the filter and other parameters. During operation, a stage I filtering operation performs a portion of the filter, and temporarily stores the result in a storage element. If the filter is a one-dimensional filter, then the results are sent to be post-processed. If the filter is a two-dimensional filter, then a stage II filtering process is performed or the intermediate results are added together, based on whether the filter is separable or non-separable. These results are then post-processed.
    • 在一个实施例中,用于滤波输入像素数据的方法和装置可配置为执行一维或二维滤波处理。 此外,在一个实施例中,二维滤波器可以被配置为执行可分离或不可分离的滤波器。 可以配置过滤器的类型,以及过滤器的尺寸和其他参数。 在操作期间,阶段I过滤操作执行过滤器的一部分,并将结果临时存储在存储元件中。 如果过滤器是一维过滤器,则将结果发送到后处理。 如果滤波器是二维滤波器,则基于滤波器是否可分离或不可分离,执行阶段II滤波处理或将中间结果相加在一起。 然后对这些结果进行后处理。
