The Render Output Unit, often abbreviated as "ROP", and sometimes called (perhaps more properly) Raster Operations Pipeline, is one of the final steps in the rendering process of modern 3D accelerator boards. The pixel pipelines take pixel and texel information and process it, via specific matrix and vector operations, into a final pixel or depth value. The ROPs perform the transactions between the relevant buffers in the local memory - this includes writing or reading values, as well as blending them together.
Historically the number of ROPs, texture units, and pixel shaders have been equal. However, as of 2004, several GPUs have decoupled these areas to allow optimum transistor allocation for application workload and available memory performance. As the trend continues, it is expected that graphics processors will continue to decouple the various parts of their architectures to enhance their adaptability to future graphics applications. This design also allows chip makers to build a modular line-up, where the top-end GPU are essentially using the same logic as the low-end products.作者: 我最野蛮 时间: 2010-10-20 22:35

The output-merger (OM) stage generates the final rendered pixel color using a combination of pipeline state, the pixel data generated by the pixel shaders, the contents of the render targets, and the contents of the depth/stencil buffers. The OM stage is the final step for determining which pixels are visible (with depth-stencil testing) and blending the final pixel colors.
