Semiconductor device and control method thereof for processing

A semiconductor device comprising:

• a configuration information storage memory that stores a plurality of configuration information items;
• a processor accessing the configuration information storage memory and configured to:
• select any one of the plurality of configuration information items;
• and
• dynamically reconfigures a circuit according to the configuration information item selected, wherein
• when a detection of a failure or no failure is made in any one of a plurality of logic circuit groups, the processor selects the configuration information item depending on a result of the detection.

A semiconductor device comprising:

• a configuration information storage memory that stores a plurality of configuration information items;
• a state transition management unit that selects any one of the plurality of configuration information items;
• and
• a data path unit that dynamically reconfigures a circuit according to the configuration information item selected by the state transition management unit, wherein
• when a failure is detected in any one of a plurality of logic circuits provided in the data path unit, a plurality of first processing circuits are configured using some or all of the plurality of logic circuits, and a final result of processing by the first processing circuits is determined according to results of processing by the respective plurality of first processing circuits.
