摘要： An anisotropic filtering technique includes defining pixel elements in two dimensions and defining at least one object having three dimensional surfaces in a three-dimensional model space and storing texel elements in two dimensions defining a texture map bearing a relationship to the three dimensional surfaces of the at least one object. Each pixel element to be texture mapped is divided into a group of sub-pixel elements and the sub-pixel elements are separately texture mapped. The resultant textures of the sub-pixel elements are averaged to obtain a texture for their respective pixel element.

摘要： Provided are a method and system for activating a design test mode in a graphics card having multiple execution units. A design test mode is activated in a graphics module comprising multiple execution units coupled to a cache on a bus. The bus is configured to return test instructions from the cache to the execution units in response to a request from one execution unit for the test instructions from the cache in the design test mode. The execution units execute the test instructions during the design test mode. Interrupts are prevented during the design test mode.

摘要： A method of moving blocks of pixel data, including window-identifying data, from a source area to a destination area within a frame buffer in a computer graphics system comprises the steps of: reading a block of pixel data from the source area into a pixel cache memory; combining source tiles with destination tiles in the cache; comparing pixel window identifiers read from the frame buffer with a pixel window identifier previously stored in the memory to determine whether the pixel window identifiers read from the frame buffer match the previously stored pixel window identifier; discarding each pixel whose corresponding window identifier does not match the previously stored window identifier; and updating the frame buffer with the pixel data not discarded.

摘要： In accordance with some embodiments, a fixed function media accelerator may be preempted in the middle of processing one frame of data and still be able to resume operation later without the need to save an internal state. This ability to be preempted, without saving an internal state, may be important for supporting page fault and increasing the responsiveness of fixed function engines. Enabling preemption without the need to save the entire state reduces the complexity of the implementation in some embodiments.

摘要： A three-dimensional pixel cache for use in a computer graphics system comprises source, pattern, and destination tile caches and a barrel shift register, or rotator, that serves as an interface between the tile caches and a frame buffer. The rotator has the capability of performing three types of rotation of data read/written from/to the tile caches horizontal rotation, vertical rotation, and rotation of nibbles within each pixel.

摘要： A circuit for performing window-relative dithering of intensity data comprises a programmable dither cell; circuitry for comparing dither values stored in the dither cell with selected parts of the intensity values and outputting an increment signal in accordance with the results of the comparison; a wrap prevention circuit for preventing the intensity from being incremented if incrementing would cause the intensity to wrap to a low value; and an adder for incrementing the intensity in response to the increment signal, provided it is not inhibited by the wrap prevention circuit. The dither circuit may be advantageously employed in a computer graphics system to dither pixel intensity values.
