<P>PROBLEM TO BE SOLVED: To provide an error correction circuit of a programmable logic circuit capable of dynamically performing detection, correction and restoration of an error in a configuration memory, with the error concealed, without influencing the programmable logic circuit. <P>SOLUTION: An error correction circuit 11 includes: a configuration memory 12 where configuration data indicating circuit configuration or wiring configuration of a programmable logic circuit and the error detection encoding data for the configuration data are read out from a base memory M and stored; an error detection unit 131 that detects occurrence of an error on the basis of the configuration data and the error detection encoding data; an alternative storage unit 134 that stores the configuration data prior to the occurrence of the error; a multiplexer unit 133 that switches the configuration data to the configuration data stored by the alternative storage unit 134 in response to error notification; and a reconfiguration control unit 14 that reads out the configuration data from the base memory M and writes the data in the configuration memory 12 for reconfiguration. <P>COPYRIGHT: (C)2012,JPO&INPIT |
