Reconfigurable device

Abstract

A reconfigurable device comprises a plurality of processing elements, a main memory unit that stores plural pieces of circuit configuration information, a cache unit that caches circuit configuration information forwarded to at least one of the processing elements from the main memory unit, and a cache control unit that controls forwarding of circuit configuration information from the cache unit to the processing element. The cache control unit selects circuit configuration information which must be forwarded to each processing element. When the selected circuit configuration information is not stored in the cache unit, the cache control unit reads out the circuit configuration information from the main memory unit, stores the read-out circuit configuration information in the cache unit, and sends forward the circuit configuration information to the processing element from the cache unit.
