摘要： A method and apparatus are provided for executing packed data instructions. According to one aspect of the invention, a processor includes registers, a register renaming unit coupled to the registers, a decoder coupled to the register renaming unit, and a partial-width execution unit coupled to the decoder. The register renaming unit provides an architectural register file to store packed data operands that include data elements. The decoder is to decode a first and second set of instructions that each specify one or more registers in the architectural register file. Each of the instructions in the first set specify operations to be performed on all of the data elements. In contrast, each of the instructions in the second set specify operations to be performed on only a subset of the data elements. The partial-width execution unit is to execute operations specified by either the first or second set of instructions.

摘要： A method and apparatus for updating the architectural state in a system implementing staggered execution with multiple micro-instructions. According to one aspect of the invention, a method is provided in which a macro-instruction is decoded into a first and second micro-instructions. The macro-instruction designates an operation on a pieced of data, and execution of the first and second micro-instructions separately cause the operation to be performed on different parts of the piece of data. The method also requires that the first micro-instruction is executed irrespective of the second micro-instructions (e.g., at a different time), and that it is detected that said second micro-instruction will not cause any non-recoverable exceptions. The results of the first micro-instruction are then used to update the architectural state in an earlier clock cycle than said second micro-instruction.

摘要： The present invention is directed to a method and apparatus for processing normalized meshes. The normalized meshes are formed by N polygons which have M vertices. M vertex coordinates are stored in a vertex array corresponding to the M vertices of the N polygons. N polygon indices are stored in an index array. Each of the N polygon indices references a predetermined number of the M vertex coordinates. A first subset of the index array having N1 polygon indices is determined. A second subset of the vertex array is selected such that the second subset contains M1 vertex coordinates corresponding entirely to the N1 polygon indices in the first subset. The second subset defines a window having a small size relative to the vertex array. The M1 vertex coordinates in the second subset are processed to generate processed data. The processed data are then concurrently sent to a graphics processor in an on-line manner.

摘要： A method and apparatus are provided for executing scalar packed data instructions. According to one aspect of the invention, a processor includes a plurality of registers, a register renaming unit coupled to the plurality of registers, and a decoder coupled to the register renaming unit. The register renaming unit provides an architectural register file to store packed data operands each of which include a plurality of data elements. The decoder is configured to decode a first and second set of instructions (e.g., a set of full-width packed data instructions and a set of partial-width packed data instructions) that each specify one or more registers in the architectural register file. Each of the instructions in the first set of instructions specify operations to be performed on all of the data elements stored in the one or more specified registers. In contrast, each of the instructions in the second set of instructions specify operations to be performed on only a subset of the data element stored in the one or more specified registers.
