    摘要: A system and method for rasterizing and rendering graphics data is disclosed. Vertices may be grouped to form primitives such as triangles, which are rasterized using two-dimensional arrays of samples bins. To overcome fragmentation problems, the system's sample evaluation hardware may be configured to over-evaluate samples each clock cycle. Since a number of the samples will typically not survive evaluation because they will be outside the primitive being rendered, the remaining surviving samples may be combined into sets, with one set being forwarded to subsequent pipeline stages each clock cycle in order to attempt to keep the pipeline utilization high.

    摘要: A system including a receiver, a TMDS link (or other serial link), and a transmitter configured to transmit K-bit video words (typically, encoded 8-bit video words) over the link. In typical embodiments, the transmitter is configured to pack a sequence of N-bit video words, where N≠K (e.g., N=10, 12, or 16, when K=8) into a sequence of K-bit fragments, encode the fragments, and transmit the encoded fragments. The transmitted data are indicative of a sequence of M-fragment groups, and the transmitter is typically configured also to transmit over the link packing phase data indicative of the phase of the most recently transmitted fragment. Other aspects are transmitters and receivers for use in such a system and methods implemented by any such transmitter, receiver, or system.

    摘要: A data queue optimized for receiving loosely packed graphics data and suitable for use in a computer graphics system is described. The data queue operates on first-in-first-out principals, and has a variable width input and output. The variable width on the input side facilitates the reception and storage of loosely packed data. The variable width output allows for the single-cycle output of multi-word data. Packing of the data occurs on the write-side of the FIFO structure.

    摘要: A computer graphics system that utilizes a super-sampled sample buffer and a sample-to-pixel calculation unit for refreshing the display. The graphics system may have a graphics processor, a super-sampled sample buffer, and a sample-to-pixel calculation unit. The graphics processor renders samples into the sample buffer and may utilize a window ID that specifies attributes of pixels on a per object basis. The window ID may specify one or more of a sample mode, filter type, color attributes, or source attributes. The sample mode may include single sample per pixel mode and multiple samples per pixel mode. The graphics system may be further operable to generate a single sample per pixel for certain windows of the screen in order to provide backwards compatibility with legacy systems.

    摘要: A high-speed ring topology. In one embodiment, two base chip types are required: a “drawing” chip, LoopDraw, and an “interface” chip, LoopInterface. Each of these chips have a set of pins that supports an identical high speed point to point unidirectional input and output ring interconnect interface: the LoopLink. The LoopDraw chip uses additional pins to connect to several standard memories that form a high bandwidth local memory sub-system. The LoopInterface chip uses additional pins to support a high speed host computer host interface, at least one video output interface, and possibly also additional non-local interconnects to other LoopInterface chip(s).

    摘要: In a class of embodiments, the invention is an open computing system (e.g., a PC) in which a protected, closed subsystem is embedded. The closed subsystem typically includes multiple parts that ensure that content protection keys and protected content are never revealed outside the closed subsystem. Content (e.g., high-definition digital video) that enters the closed subsystem (and is typically decrypted and re-encrypted within the closed subsystem) is afforded a similar level of protection within the open system as can be obtained in standalone closed systems. Other aspects of the invention are methods for protecting content within an open computing system, a closed system (or disk drive thereof) configured to be embedded in an open computing system, and circuitry configured to be embedded in an open computing system for combining the output of a closed subsystem with other output (e.g., graphics and/or audio output) of the open computing system.
