摘要： A configurable filter module for providing shared filter resource between an overlay engine and a texture mapping engine of a graphics system. The configurable filter may comprise a plurality of linear blend units each of which receives data input from one of the overlay engine and a mapping engine cache, and generates a linear blend filter output respectively; and a filter output multiplexer which receives data output from the linear blend units and selects a proper byte ordering output, wherein the linear blend units serve as an overlay interpolator filter to perform linear blending of the data input from the overlay engine during a linear blend mode, and serve as a texture bilinear filter to perform bilinear filtering of the data input from the mapping engine cache during a bilinear filtering mode.

摘要： A method and apparatus for managing overlay data requests are disclosed. One embodiment of an apparatus includes a request unit and a timer. A request is made by a graphics controller to the request unit for a line of overlay data. The request unit divides the request from the graphics controller into a series of smaller requests. The smaller requests are issued to a memory controller. Delays are inserted between each of the smaller requests in order to allow other system resources to more easily gain access to memory.

摘要： A computer graphics processor capable of reading from, and writing to, virtual memory. The invention provides a graphics processing unit which includes, among other things, an graphic processor in the form of an address generator which retrieves data from memory locations, and writes data to memory locations. The address generator retrieves data from memory locations memory access request directly to a memory control unit, which retrieves the contents of the memory location. Prior to issuing the request, the address generator sends the address to a virtual translation unit, which translates the virtual address to a physical address. The virtual translation/FIFO control unit also contains three translation buffers, in which are stored the most recently accessed virtual addresses, which, in many situations, enables the virtual translation/FIFO control unit to translate the virtual address using less memory accesses.

摘要： In a computer graphics system, an address generator processes physical and virtual addresses using a common command set. A separate translator provides conversion from generated virtual addresses to physical addresses. The address generator formulates addresses as a function of distance from the origin of desired destination area in destination memory to the requested position in the destination area. A plurality of drawing graphics commands specify different raster drawing operations. A plurality of context graphics commands is used to define a desired context in which drawing graphics commands operate. The defined context includes destination location for resulting data, type and plane depth of graphics operations, foreground and/or background color of resulting data. Different parts of the context are changeable/redefinable independently of the other parts.

The address generator formulates addresses as a function of distance from the origin of the desired destination area in a destination memory to the requested position in the destination area. A plurality of context drawing commands is used to define a desired context in which drawing graphics commands operate. Different parts of the context are changeable/redefinable independently of the other parts. Graphics commands have a format of multiple fields having corresponding parameters arranged in order of common use of the parameter such that fields of less commonly used parameters are at an omittable end of the format. Raster drawing commands are delimited by a beginning and end indicator to form a drawing unit. For clip list processing, a drawing unit is stored as a single occurrence in the system command buffer.

摘要： A residue buffer, for temporary storage of portions of transmissions from a CPU to a graphics processor. Graphics commands are transmitted, in transmission units of uniform size, from a processor unit to an address generator, which processes the commands. The portion of the transmission unit not immediately usable by the graphics processor is stored in the residue buffer. The disclosure further describes a computer graphics system, having a graphics processor capable of reading from or writing to main memory, including virtual memory, without any action by the CPU; having a duplicate cache tag store accessible by the graphics system without generating traffic on the system bus; having a FIFO command buffer in main memory for temporary storage of graphics commands; having a "short circuit" feature for routing graphics commands to the command processor in the minimum number of steps; having a cursor control system capable of storing cursor pattern information in, and retrieving cursor pattern information from, main memory; having a cursor bus that is reconfigurable to carry information other than cursor information; and having a frame buffer module that contains no timing or cursor control circuitry.

For each graphics command, the fields are arranged in order of common use of the corresponding parameter such that fields of less commonly used parameters are at an omittable end of the format. Thus, length of each graphics command varies as a function of parameters specified in the graphics command. A desired set of raster drawing commands delimited by a beginning indicator and an end indicator form a drawing unit.
