  • Publication number: 20070043795
    Abstract: An apparatus for performing alignment shifting in a floating-point unit is disclosed. An alignment shifter includes a shift amount calculator, a set of first level shifters and a set of second level shifter. The shift amount calculator generates one shift amount under a double-precision mode and two shift amounts under a single-precision mode. The first level shifters can concurrently receive two double-precision mantissas under the double-precision mode or two single-precision mantissas under the single-precision mode. The first level of shifts performs small shifts concurrently on the two double-precision mantissas according to the single shift amount, or on the two single-precision mantissas according to the two shift amounts. The second level shifters performs large shifts on outputs from the first level shifters to generate one double-precision floating-point result or two single-precision floating-point results.

  • Publication number: 20070011222
    Abstract: A system and method for processing single-precision floating-point numbers. The system includes a processor that has a double-precision (DP) register, wherein the DP register receives a plurality of single-precision (SP) operands, and a recoder coupled to the DP register, wherein the recoder recodes a first SP operand of the plurality of SP operands. The processor also includes a plurality of partial product (PP) units coupled to the DP register, wherein each PP unit of the plurality of PP units processes a second SP operand of the plurality of SP operands.
