You can use Altera

®

integer megafunction IP cores to perform mathematical operations in your design.

These functions offer more efficient logic synthesis and device implementation than coding your own

functions. You can customize the IP cores to accommodate your design requirements.
Altera integer arithmetic megafunctions are divided into the following two categories:
• Library of parameterized modules (LPM) IP cores

• Altera-specific (ALT) IP cores
The following table lists the integer arithmetic IP cores.
