A detailed description of how to use bitstream encryption is
provided in the Virtex-II User Guide. Your local FAE can also
provide specific information on this feature.
Partial Reconfiguration
Partial reconfiguration of Virtex-II devices can be accom-
plished in either Slave SelectMAP mode or Boundary-Scan
mode. Instead of resetting the chip and doing a full configu-
ration, new data is loaded into a specified area of the chip,
while the rest of the chip remains in operation. Data is
loaded on a column basis, with the smallest load unit being
a configuration “frame” of the bitstream (device size depen-
dent).
Partial reconfiguration is useful for applications that require
different designs to be loaded into the same area of a chip,
or that require the ability to change portions of a design
without having to reset or reconfigure the entire chip.
