ABSTRACT:
Some embodiments of the invention provide a reconfigurable IC that has several reconfigurable circuits. Each reconfigurable circuit for configurably performing a set of operations and for reconfiguring at a first frequency. The reconfigurable IC also has at least one reconfiguration signal generator for receiving a clock signal at a second frequency and producing a set of reconfiguration signals with a third frequency. The reconfiguration signals are supplied to the reconfigurable circuits to direct the reconfiguration of the reconfigurable circuits at the first frequency.
