On the role of composition in XQuery
Nonrecursive XQuery is known to be hard for nondeterministic exponential time. Thus it is commonly believed that any algorithm for evaluating XQuery has to require exponential amo...

A parallel/vectorized double-precision exponential core to accelerate computational science applications
Many natural processes exhibit exponential decay and, consequently, computational scientists make extensive use of e−x in computer simulation experiments. While it is common to ...

Double-Exponentiation in Factor-4 Groups and Its Applications
In previous work we showed how to compress certain prime-order subgroups of the cyclotomic subgroups of orders 22m + 1 of the multiplicative groups of F∗ 24m by a factor of 4. We...

Exponential split accumulator for high-speed reduced area low-power direct digital frequency synthesizers
A new split accumulator architecture to be used in direct digital frequency synthesizers (DDFS) systems is presented. This new design eliminates the need of adders on the section ...
