Enhanced Configuration and Configuration via Protocol
35
Apart from lowering cost and power consumption, partial reconfiguration increases the effective logic density
of the device because placing device functions that do not operate simultaneously is not necessary. Instead,
you can store these functions in external memory and load them whenever the functions are required. This
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 solution,
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.
