    摘要： A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. A relatively low chip-footprint, versatile texture environment (TEV) processing subsystem is implemented in a pipelined graphics system circulates computed color and alpha data over multiple texture blending/shading cycles (stages). The texture-environment subsystem combines per-vertex lighting, textures and constant (rasterized) colors to form computed pixel color prior to fogging and final pixel blending. Blending operations for color (RGB) and alpha components are independently processed by a single sub-blend unit that is reused over multiple processing stages to combine multiple textures.

    摘要： Embodiments of a distributed memory controller system implemented on a single integrated circuit device are described. In one embodiment, a memory controller that provides an interconnection circuit between a first plurality of memory devices to a second plurality of memory clients includes a ring bus to route at least one of the memory request and data return signals between the memory clients and the memory devices. The ring bus is configured in a ring topography that is distributed across a portion of an integrated circuit device, resulting in a reduction in the maximum wiring density at the center of memory controller. The ring bus structure also reduces the overall number of interconnections as well as the number of storage elements, thus reducing the total area used by the memory controller.

    摘要： A system and method that determines the direction of an edge in a video image using a gradient of the edge in a first direction and a gradient of the edge in a second direction. The system uses the sign of the product of the gradient in the first direction and the gradient in the second direction along with a ratio of multiples of the two gradients to determine the direction of the edge. The direction may correspond to an angle range, where the ratio of the gradients corresponds to a trigonometric function of the angle of the edge.
