The reciprocal operation involves iterative execution of a refinement step to converge on the result value, the refinement step performing the computation: Xi=Xi−1*M, where Xi is ... 05/04/06 - 20060095494 - Method and apparatus for efficient software-based integer division A method and apparatus to perform efficient software-based integer division. The equivalent of a hardware-based integer division operation is enabled via a reciprocal multiplication operation that is facilitated by a minimum combination of multiplication (and/or add) and shift operations. Properties and equations are derived for determining minimum multiplication and shift ... 03/09/06 - 20060053192 - Apparatus and method for implementing efficient arithmetic circuits in programmable logic devices Efficient implementation of arithmetic circuits in programmable logic devices by using Look-Up Tables (LUTs) to store pre-calculated values. A table look-up operation is performed in place of complex arithmetic operations. In this way, at the expense of a few LUTs, many logic elements can be saved. This approach is particularly ... 12/29/05 - 20050289208 - Methods and apparatus for determining quotients Methods, apparatus, and articles of manufacture for determining quotient values are disclosed. An example method identifies a reciprocal value of a divisor value. A bias value is then identified and a biased quotient value is determined based on a dividend value, the reciprocal value, and at least a portion of ... 08/18/05 - 20050182811 - Method and apparatus supporting non-additive calculations in graphics accelerators and digital signal processors A method and apparatus receiving number and using instruction to create resulting number approximating one of square root, reciprocal, or reciprocal square root of number. The resulting number as a product of that process. Using resulting number in a graphics accelerator. Apparatus preferably includes log-calculator, log-arithmetic-unit, and exponential-calculator. At least ... ### FreshPatents.com Support |
