Abstract
There is provided a reconfigurable device that includes a plurality of processing blocks (13), wherein operation logic of each processing block is changeable, and a routing matrix (15) for configuring paths that connect the plurality of the processing blocks. Each processing block (13) includes a logic operation unit (21) whose logic is determined by configuration data (17) and a storage unit (40) for storing processing results of the logic operation unit. Each storage unit (40) includes a plurality of storage elements (31r), input means (32) for selecting one of the plurality of storage elements (31r) based on the configuration data (17) to store the output of the logic operation unit (21), and output means (33) for connecting the plurality of storage elements (31r) to the routing matrix (15).
