Abstract: Systems, apparatuses, and methods for generating a blur effect on a source image in a power-efficient manner. Pixels of the source image are averaged as they are read into pixel buffers, and then the source image is further downscaled by a first factor. Then, the downscaled source image is upscaled back to the original size, and then this processed image is composited with a semi-transparent image to create a blurred effect of the source image.
Abstract translation: 以功率有效的方式在源图像上产生模糊效果的系统，装置和方法。 源图像的像素在被读取到像素缓冲器中时被平均，然后源图像被第一因子进一步缩小。 然后，将缩小的源图像放大到原始尺寸，然后将该处理后的图像与半透明图像合成，以产生源图像的模糊效果。

Abstract: A display pipe is configured to generate output frames for display. Additionally, the display pipe may be configured to compress an output frame and write the compressed frame back to memory responsive to detecting static content in successive output frames. The display pipe may also be configured to determine to selectively allow write-back logic to operate when doing so will not cause a pixel underrun to the display. If an underrun might occur, write-back logic is temporarily disabled. If write-back is successful, the display pipe may read the compressed frame from memory for display instead of reading the source frames for compositing and display.
Abstract translation: 显示管被配置为生成用于显示的输出帧。 此外，显示管可以被配置为压缩输出帧并且响应于检测连续输出帧中的静态内容而将压缩帧写回存储器。 显示管还可以被配置为确定选择性地允许回写逻辑操作，这样做将不会导致像素超出显示。 如果发生欠载，则暂时禁用回写逻辑。 如果回写成功，显示管道可以从存储器读取压缩帧以进行显示，而不是读取用于合成和显示的源帧。
