Latest Patents

One of his latest patents is titled "Multiple scan line sample filtering." This invention presents a system and method for generating pixels for a display device. The system includes a sample buffer for storing multiple samples in 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 can be stored in a frame buffer or provided directly to a display device. The method optimizes the use of common samples shared by neighboring pixels in both the x and y directions, which reduces sample buffer accesses and enhances performance. It involves reading samples from memory that correspond to pixels in neighboring scan lines and possibly multiple pixels in each of these lines. The samples are stored in cache memory and accessed for filtering, maximizing the use of common samples.

Another significant patent is the "Frame buffer addressing scheme." This graphics system includes a frame buffer with one or more memory devices and a frame buffer interface. Each memory device contains N banks, with each bank having multiple pages configured to store data for a portion of a screen region. The frame buffer interface generates addresses used to store data corresponding to a frame of data in the frame buffer, ensuring that each bank stores data for a portion of one out of every N screen regions within a horizontal group.
