Some embodiments provide an integrated circuit (IC) that has a first interface rate for exchanging signals in at least one direction with a circuit outside of the IC. The IC has multiple reconfigurable circuits. Each of the reconfigurable circuits is for reconfiguring at a second rate. The second rate is faster than the first interface rate. Each of the reconfigurable circuits reconfigures when configuration data that specifies an operation of the particular reconfigurable circuit changes from a first configuration data set that is stored in the IC to a second configuration data set that is also stored in the IC.
