IP Core

2014.08.18
UG-01156
The CPRI v6.0 IP core achieves low latency and lower resource utilization than the legacy CPRI IP core
and provides new interfaces for direct access to the CPRI frame. The signals, registers, and register fields
are different: you cannot simply substitute the new IP core for the legacy IP core in your design without
additional design work.
To compare the CPRI v6.0 IP core to previous releases of the CPRI IP core, refer to the table and to the
Altera documentation about the revision history of the CPRI IP core.
Table A-1: Major Differences Between the CPRI v6.0 IP Core Initial Release and the CPRI IP Core
The Altera CPRI IP core is a product available through several previous Altera software releases. The differences
in signals, registers, and register fields are too numerous to list in this table.
The comparison is defined relative to the version of the legacy CPRI IP core available with the Altera software
release v14.0.
