PROBLEM TO BE SOLVED: To provide a programmable logic circuit device capable of achieving cache logic technologies with which a total data processing time can be reduced. SOLUTION: The programmable logic circuit device comprises: a programmable logic circuit part in which a circuit is reconfigured based on circuit information written into a configuration memory; a circuit information input control means for writing circuit information input from the outside into the configuration memory under control from the outside; a data cache means for temporarily holding data to be processed by the reconfigured circuit; an input data switching means to be switched under control from the outside so as to supply either data from the data cache means or input data to the reconfigured circuit; and an output data switching means capable of switching, under control from the outside, whether output data of the reconfigured circuit are to be supplied to the data cache means or to be derived as output data.
