Configuration control system and configuration control method

Abstract

An FPGA can be started up without system failure when a soft error occurs. A configuration control system includes: a first semiconductor chip which is capable of programming a logic circuit inside an LSI; a semiconductor memory which stores a plurality of pieces of circuit information of the first semiconductor chip; and a second semiconductor chip which, when controlling a configuration of the semiconductor chip using the circuit information stored in the semiconductor memory, if the configuration using any one of the plurality of pieces of circuit information fails, performs a re-configuration using another piece of circuit information among the plurality of pieces of circuit information.

 configuring, by a controller, the logic device using the first circuit information;   confirming that the configuring of the logic device completed successfully;   confirming that the first circuit information was used in the successful configuration of the logic device.   
     
     
         2 . The configuration control method according to  claim 1 , further comprising notifying, by the controller, that the first circuit information was used to perform the successful configuration of the logic device. 
     
     
         3 . The configuration control method according to  claim 1 , wherein the first and the second circuit information are stored in a same single memory. 
     
     
         4 . The configuration control method according to  claim 1 , wherein the first and the second circuit information are respectively stored in two different memories. 
     
     
         5 . The configuration control method according to  claim 1 , wherein the logic device is a field programmable gate array (FPGA).
