  • Conversion from packed floating point data to packed 16-bit integer data in different architectural registers
    Patent number: 6247116
    Abstract: A method and instruction for converting a number from a floating point format to an integer format are described. Numbers are stored in the floating point format in a register of a first set of architectural registers in a packed format. At least one of the numbers in the floating point format is converted to at least one 16-bit number in the integer format. The 16-bit number in the integer format is placed in a register of a second set of architectural registers in the packed format.

  • Pipelined processing of short data streams using data prefetching
    Patent number: 6223276
    Abstract: The present invention discloses a method and apparatus for processing strips of data, each strip referencing a plurality of parameter sets stored in a memory. The method comprises: prefetching a plurality of parameter sets referenced in a first strip; performing an operation on each of the prefetched parameter sets; and concatenating a first strip and a second strip to eliminate a memory access latency in the second strip.

  • Method and apparatus for parallel conversion of color values from a single precision floating point format to an integer format
    Patent number: 5995122
    Abstract: 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.
