Abstract: A semiconductor device includes a configuration memory for storing configuration data, an arithmetic unit whose circuit configuration can be reconfigured in accordance with the configuration data, and a fixed value memory for storing fixed value data to be supplied to the arithmetic unit. Since the configuration data and fixed value data to be supplied to the arithmetic unit are stored in the different memories, no data area for storing the fixed value data need be set in the configuration memory. This makes it possible to supply a predetermined fixed value to the arithmetic unit by storing only information for reading out fixed value data from the fixed value memory.

Abstract: A reconfigurable processor in which an application can be switched more freely. A switching condition associating section associates output from a plurality of arithmetic and logic unit modules used as switching conditions for switching the operation of an arithmetic and logic unit group with a plurality of states indicative of switching condition codes. When a switching condition code output section decides that a switching condition comes into existence on the basis of the output from the plurality of arithmetic and logic unit modules set as the switching conditions, the switching condition code output section outputs a switching condition code corresponding to the switching condition which comes into existence. When a sequencer accepts the switching condition code, the sequencer switches the arithmetic and logic unit group to a state corresponding to the switching condition code.
