REAL-TIME DISPLAY POST-PROCESSING USING PROGRAMMABLE HARDWARE

摘要

In the graphics processor, a rendering object and the post-processing object share the execution core programs access to the host processor. Rendering object generates fragment data for an image from geometry data. After processing object generating a frame of pixel data from the fragment data and operates to store the pixel data in the frame buffer. In parallel with the operation of the host processor, the scan-out engine reads pixel data for a previously generated frame and supplies the pixel data to a display device. Scanout engine periodically triggers the host processor, operates the handling object then to generate a subsequent frame. The timing between the scan-out the engine and the post-processing object, the scan-out the engine has, can be controlled to be displayed in the subsequent frame is ready in the frame buffer when the end of reading the current frame. ; A graphics processor, a real-time display, the post-processing object, fragment data, pixel data, and rendering objects, the host processor, the scan-out the engine, the frame buffer
