When multiple Stratix III devices are cascaded, you can selectively enable
the compression feature for each device in the chain if you are using a
serial configuration scheme.
devices. The first Stratix III device has compression enabled and therefore
receives a compressed bitstream from the configuration device. The
second Stratix III device has the compression feature disabled and
receives uncompressed data.
In a multi-device FPP configuration chain (with a MAX II
device/microprocessor + flash), all Stratix III devices in the chain must
either enable or disable the decompression feature. You can not
selectively enable the compression feature for each device in the chain
because of the DATA and DCLK relationship.
