摘要： A method and apparatus for parallel processing of graphics data are described. A number of color components are stored in a floating point format in at least one register of a set of 128-bit registers in a packed format. The color components in the floating point format are converted to numbers in an integer format. The numbers in the integer format are placed in at least one register of a set of 64-bit registers in the packed format. Color components are assembled for image pixels from the numbers in the integer format.

摘要： A method and apparatus for reducing the number of opcodes required in a computer architecture using an operation class code and an operation selector code. A processor contains a fetch unit which fetches instructions to be executed by the processor. An instruction may conform to an instruction format which includes a number of fields that specify an operation class code, an operation selector code, and one or more operands. The processor also contains a decoder which uses the operation class code to generate a single execution flow that is capable of executing a class of similar operations. The single execution flow, in the form of execution control information, is sent to an execution unit along with the associated operands. The operation selector code is also passed to the execution unit. The execution unit performs the specific operation identified by the operation selector code and execution control information.

摘要： A method comprises decoding a single instruction having a first operand identifying a plurality of bytes of packed data and a second operand identifying a corresponding plurality of byte masks. Each of the plurality of byte masks identified by the second operand of the single decoded instruction are analyzed, wherein select bytes of the plurality of bytes identified by the first operand are moved to an implicitly defined location based, at least in part, on the analysis of the individual byte masks identified by the second operand of the single decoded instruction.
