Embodiment Construction
[0038] figure 1 It is a schematic diagram of a cache access system 100 according to an embodiment of the present invention. The cache access system 100 includes a cache 110 and a control unit 120 . In some embodiments of the present invention, the cache access system 100 can be applied to image compression.
[0039] In practice, in order to improve the utilization efficiency of hardware resources, when compressing the data of a frame, a frame can be divided into multiple image tiles (tiles) and / or multiple image blocks (blocks). Each image block in a frame is compressed sequentially. For example, the original picture can be divided into 2 A x2 B image tiles, and each image tile contains 2 ΔX x2 ΔY blocks, wherein A, B, ΔX and ΔY are natural numbers, that is, zero or positive integers.
[0040] figure 2 It is a schematic diagram of the image tiles and image blocks of the original picture IMG1 according to an embodiment of the present invention. figure 2 In an exampl...
