Financial applications run time can be expedited by factors of up to 20x. Data center footprint – TCO and energy consumption – would potentially be reduced by unprecedented 80% or more; depending on their DFP operations percent.
SilMinds core units can be combined in a reconfigurable way to optimize the arithmetic operations execution pipes with respect to the specific application’s native computing patterns.

SilMinds Decimal IP family presents new designs for decimal floating point (DFP) addition, multiplication, fused multiply-add division, and square root. Our products emphasize the importance of energy savings achieved by hardware implementations of the IEEE 754-2008 standard for decimal floating point.
SilMinds is the first company worldwide to discuss energy savings in DFP and the first to present a hardware implementation of a fused multiply-add function. Our Newton-Raphson based divider is over three times faster than the similar design previously reported.
