OPTIMIZING IMAGE MEMORY ACCESS

摘要

An apparatus and system for accessing an image in a memory storage is disclosed herein. The apparatus includes logic to pre-fetch image data, wherein the image data includes pixel regions. The apparatus also includes logic to arrange the image data as a set of one-dimensional arrays to be linearly processed. The apparatus further includes logic to process a first pixel region from the image data, wherein the first pixel region is stored in a cache. Additionally, the apparatus includes logic to place a second pixel region from the image data into the cache, wherein the second pixel region is to be processed after the first pixel region has been processed, and logic to process the second pixel region. Logic to write the set of one-dimensional arrays back into the memory storage is also provided, and the first pixel region is evicted from the cache.

1. An apparatus for accessing an image in a memory storage, comprising:
logic to pre-fetch image data, wherein the image data comprises pixel regions; logic to arrange the image data as a set of one-dimensional arrays to be linearly processed; logic to process a first pixel region from the set of one-dimensional arrays, the first pixel region being stored in a cache; logic to place a second pixel region from the set of one-dimensional arrays into the cache, wherein the second pixel region is to be processed after the first pixel region has been processed; logic to process the second pixel region; logic to write the processed pixel regions of the set of one-dimensional arrays back into the memory storage; and logic to evict the pixel regions from the cache.
