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.

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： An external cache management unit for use with 3D-RAM and suitable for use in a computer graphics system is described. The unit maintains and tracks the status of level one cache memory in the 3D-RAM. The unit identifies dirty blocks of cache memory and prioritizes block cleansing based on a least used algorithm. Periodic block cleansing during empty memory cycles is provided for, and may also be prompted on demand.

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： One embodiment of a method of performing a font operation involves receiving a set of font data identifying a font operation to be performed. If a first font data unit in the set indicates that a first coordinate should be a background color and transparent background is enabled, the method involves outputting an enable for a second font data unit in the set. The second font data unit indicates that a second coordinate should be a foreground color. The enable for the second coordinate is output instead of a disable for the first coordinate. If instead the first font data unit in the set indicates that the first coordinate should be a background color and transparent background is disabled, the method may involve outputting a disable for the first coordinate.

摘要： A graphics system configured to operate on a collection of vertices to determine mappings from an initial order to secondary and tertiary ordering. The initial order corresponds to the ordering of the vertices in an input buffer. The secondary (tertiary) ordering corresponds to the ordering of the vertices along a triangle major (minor) axis. The graphics system computes horizontal and vertical displacements along edges of the triangle in the initial ordering, and uses the signs of the horizontal displacements and vertical displacements to access a mapping table which determines the mappings. The mappings may be used to rasterize the triangle in terms of pixels (or samples).
摘要翻译：图形系统被配置为对顶点集合进行操作以确定从初始顺序到二次和三次排序的映射。初始顺序对应于输入缓冲区中顶点的顺序。次级（三级）排序对应于沿着三角形主（次）轴的顶点的顺序。图形系统在初始排序中计算沿着三角形边缘的水平和垂直位移，并使用水平位移和垂直位移的符号来访问确定映射的映射表。映射可以用于根据像素（或样本）来对三角形进行光栅化。
