Differences Between Low Latency 40-100GbE
IP Core and 40-100GbE IP Core v15.0

The Low Latency 40-100GbE MegaCore function provides new functionality, and also sacrifices some
dynamic configuration options and features to achieve low latency and lower resource utilization than the
legacy 40-100GbE MegaCore function. In some cases, parameter options allow you to configure the Low
Latency IP core to include or exclude features that are dynamically configurable in the legacy IP core,
providing you the flexibility to achieve resource savings by removing features your design does not
require.
To compare the Low Latency 40-100GbE MegaCore function to previous releases of the 40-100GbE
MegaCore function, refer to the table and to the Altera documentation about the revision history of the
legacy 40-100GbE MegaCore function.
Table C-1: Major Differences Between the Low Latency 40-100GbE IP Core v15.0 and the 40-100GbE IP
Core v15.0
Lists the basic differences between the Altera 40- and 100-Gbps Ethernet MAC and PHY (40-100GbE) MegaCore
function, a product available through several previous Altera software releases, and the Low Latency 40- and 100-
Gbps Ethernet MAC and PHY (Low Latency 40-100GbE, or LL 40-100GbE) MegaCore function in its current
release.
