Abstract: A patch memory system for accessing patches from a memory is disclosed. A patch is an abstraction that refers to a contiguous, array of data that is a subset of an N-dimensional array of data. The patch memory system includes a tile cache, and is configured to fetch data associated with a patch by determining one or more tiles associated with an N-dimensional array of data corresponding to the patch, and loading data for the one or more tiles from the memory into the tile cache. The N-dimensional array of data may be a two-dimensional (2D) digital image comprising a plurality of pixels. A patch of the 2D digital image may refer to a 2D subset of the image.

Abstract translation: 公开了一种用于从存储器访问补丁的补丁存储器系统。 补丁是指一个连续的数据数组的抽象，它是N维数据数组的子集。 所述补丁存储器系统包括瓦片高速缓存，并且被配置为通过确定与对应于所述补丁的N维数组阵列相关联的一个或多个瓦片来提取与补丁相关联的数据，以及将所述一个或多个瓦片的数据从 内存进入瓦片缓存。 N维数据阵列可以是包括多个像素的二维（2D）数字图像。 2D数字图像的补丁可以指图像的2D子集。
