摘要： A system and method for generating pixels for a display device. The system may include a sample buffer for storing a plurality samples in a memory, a sample cache for caching recently accessed samples, and a sample filter unit for filtering one or more samples to generate a pixel. The generated pixels may then be stored in a frame buffer or provided to a display device. The method operates to take advantage of the common samples shared by neighboring pixels in both the x and y directions for reduced sample buffer accesses and improved performance. The method involves reading samples from the memory that correspond to pixels in a plurality of neighboring scan lines, and possibly also to multiple pixels in each of these scan lines. The samples may be stored in a cache memory and then accessed from the cache memory for filtering. The method maximizes use of the common samples shared by neighboring pixels in both the x and y directions.

摘要： A graphics system configured to perform programmable filtering of samples to generate pixel values. The graphics system comprises a frame buffer, an accelerator unit and a video output processor. The accelerator unit receives graphics primitives, renders samples for the graphics primitives, and stores the rendered samples into a sample area of the frame buffer. The accelerator unit subsequently reads the samples from the sample area of the frame buffer, and filters the samples with a programmable filter having a programmable support region. The resulting pixel values are stored in a pixel area of the frame buffer. The video output processor reads the pixel values from the pixel area and converts the pixel values into a video signal which is provided to a video output port.

摘要： A system and method capable of super-sampling and performing super-sample convolution are disclosed. In one embodiment, the system may comprise a graphics processor, a frame buffer, a sample cache, and a sample-to-pixel calculation unit. The graphics processor may be configured to generate a plurality of samples. The frame buffer, which is coupled to the graphics processor, may be configured to store the samples in a sample buffer. The samples may be positioned according to a regular grid, a perturbed regular grid, or a stochastic grid. The sample-to-pixel calculation unit is programmable to select a variable number of stored samples from the frame buffer, copy the selected samples to a sample cache, and filter a set of the selected samples into an output pixel. The sample-to-pixel calculation unit retains those samples in the sample cache that will be reused in a subsequent pixel calculation and replaces those samples no longer required with new samples for another filter calculation.
