Hi Alexander,
I'm sorry about such long delay, I completely forgot to answer this email.

As far as I can tell, ISE doesn't report anything. Bcrypt core is connected
to processing_sytem7 in Xilinx Platform Studio and it's synthesized as part
of processing_system7. There is no clock rate reported for it.

I will try this later today.
