Latest Patents

One of Yong He's latest patents focuses on adaptive shading in a graphics processing pipeline. This invention includes a parallel processing unit (PPU) that performs pixel shading at variable granularities. For effects that vary at a low frequency across a pixel block, a coarse shading unit performs the associated shading operations on a subset of the pixels in the pixel block. In contrast, for effects that vary at a high frequency across the pixel block, fine shading units perform the associated shading operations on each pixel in the pixel block. The PPU's ability to implement both coarse and fine shading units allows it to tune the shading rate per effect based on the frequency of variation across each pixel group. This innovation leads to reduced power consumption and increased rendering frame rates compared to conventional PPUs, which typically compute all effects per pixel, resulting in redundant shading operations for low-frequency effects.
