capability reduces the size of the device because it allows multiple applications on a single device—saving

the board space and reducing the power consumption.

Altera simplifies the time-intensive task of partial reconfiguration by building this capability on top of the

proven incremental compile and design flow in the Quartus II design software. With the Altera

you do not need to know all the intricate device architecture details to perform a partial reconfiguration.

Partial reconfiguration is supported through the FPP x16 configuration interface. You can seamlessly use

partial reconfiguration in tandem with dynamic reconfiguration to enable simultaneous partial reconfiguration

of both the device core and transceivers.

Enhanced Configuration and Configuration via Protocol

Cyclone V devices support 1.8 V, 2.5 V, 3.0 V, and 3.3 V programming voltages and several configuration

modes.

Instead of using an external flash or ROM, you can configure the Cyclone V devices through PCIe using

CvP. The CvP mode offers the fastest configuration rate and flexibility with the easy-to-use PCIe hard IP

block interface. The Cyclone V CvP implementation conforms to the PCIe 100 ms power-up-to-active time

requirement.
