Abstract: A processing unit, method, and medium for decompressing or generating textures within a graphics processing unit (GPU). The textures are compressed with a variable-rate compression scheme such as JPEG. The compressed textures are retrieved from system memory and transferred to local cache memory on the GPU without first being decompressed. A table is utilized by the cache to locate individual blocks within the compressed texture. A decompressing shader processor receives compressed blocks and then performs on-the-fly decompression of the blocks. The decompressed blocks are then processed as usual by a texture consuming shader processor of the GPU.

Abstract translation: 一种用于在图形处理单元（GPU）内解压缩或生成纹理的处理单元，方法和介质。 纹理采用可变速率压缩方案（如JPEG）进行压缩。 压缩的纹理从系统内存中检索并传输到GPU上的本地缓存内存，而无需首先解压缩。 缓存利用表来定位压缩纹理内的各个块。 解压缩着色器处理器接收压缩块，然后对块进行即时解压缩。 解压缩的块然后像通常那样由GPU的纹理消耗着色器处理器进行处理。
