Description
Includes accumulators, adders, multipliers, and LPM arithmetic
functions.
Includes multiplexers and LPM gate functions.
Includes Clock Data Recovery (CDR), phase-locked loop (PLL),
double data rate (DDR), gigabit transceiver block (GXB), LVDS
receiver and transmitter, PLL reconfiguration, and remote
update megafunctions.
Includes the FIFO Partitioner, RAM, and ROM megafunctions.
Memory and shift register megafunctions, and LPM memory
functions.
To save valuable design time, Altera recommends using megafunctions
instead of coding your own logic, where possible. These functions can offer
more efficient logic synthesis and device implementation. It is easy to scale
megafunctions to different sizes by simply setting parameters. Altera also
provides AHDL Include Files and VHDL Component Declarations for both
Altera-provided megafunctions and LPM functions.

Using Intellectual Property (IP)
Megafunctions
Altera provides several methods for obtaining both Altera Megafunction
Partners Program (AMPP ? ) and MegaCore ? megafunctions, functions that
are rigorously tested and optimized for the highest performance in Altera
device-specific architectures. You can use these parameterized blocks of
intellectual property to reduce design and test time. MegaCore and AMPP
