1. A method comprising:
- retrieving a first configuration data set from a first set of storage elements;
supplying the first configuration data set to a reconfigurable circuit of an integrated circuit (“
IC”
); and
retrieving a second configuration data set from a second set of storage elements as the reconfigurable circuit performs a first set of operations based on the first configuration data set.

Abstract
Some embodiments provide a circuit for accessing stored data in a configurable IC that includes several configurable circuits. The IC also includes several storage circuits. Each storage circuit has (1) several storage elements for storing data for the configurable circuits, and (2) output circuitry for outputting data stored in the storage elements. The output circuitry includes a first set of interconnects for receiving at least a first repeating periodic signal and for periodically outputting data from at least two storage elements to the configurable circuits.
