in weather forecasting models: An evaluation with the IFS.
The Rnd function returns a single precision
random number and has an optional argument to set the seed for the random number.
In authors describe a proficient implementation of an IEEE-754 single precision
floating-point multiplier using Vedic mathematics-as with using Vedic mathematics partial products can be reduced, so that the area and power constraints of the floating-point multiplier can be reduced efficiently.
offers more memory saving, although its precision limits to seven digits, so it could introduce numerical errors.
As input size increases, the single precision
version is approximately 40 to 60 percent faster than the pure parallel code.
IPCSR achieves average performance improvement of 1.76x (single precision
) and 1.53x (double precision) over PCSR on the C2050 GPU and 1.79x (single precision
) and 1.56x (double precision) over PCSR on the K20c GPU.
(2000) single precision
multiplier, Akkas and Schulte's (2003) quad precision multiplier, etc., all suffers with the above said crucial problems.
To realize the three reversible fused elements, the proposed design requires a reversible single precision
floating point adder, a reversible single precision
floating point subtractor and a reversible single precision
floating point multiplier.
Additionally, we make experiments with double and single precision
to calculate the errors that can introduce the single precision
, and even when its use reduces the computing time from 30% to 50%, it is necessary to evaluate the effect of the introduced error by using only seven significant digits in the floating numbers and investigate if this error affects considerably the result of the modeling.
Moreover, [[gamma].sub.k] is produced by subtraction and has very few significant bits: in variable precision, [[gamma].sub.k] is truncated to single precision
For instance, the floating-point operations they do require only single precision
and can get away with the crudest form of rounding (truncation toward zero) to save space on the chip.
The 32-bit single precision
, IEEE-754 compatible MicroBlaze FPU provides designers with a processor tailored to execute both integer and floating-point operations.
