DADiSP / ProPac
ProPac Math Acceleration Module
ProPac automatically accelerates many math computations and operations.
In addition, custom or built-in routines that make use
of these enhanced calculations experience significant speed improvements.
Below is a list of routines provided by DADiSP that benefit
directly from the ProPac Module.
