PROBLEM TO BE SOLVED: To provide an arithmetic unit for producing operation results not including errors in accordance with measured values obtained by asynchronously measuring a plurality of types of physical quantity. SOLUTION: A reception postprocessing part 4 acquires time infromation tαshowing an input time from a time generation part 3 each time a measured valueαis input from a reception processing part 3, reads out time information showing measured valuesα' input one cycle before and their input time, calculates rates of change dα, and overwrites these on the memory 5. A preprocessing part 6 reads out data from the memory 5, acquires data read-out time tn from the time generation part 2, calculates estimated dataαn by executing an operation;αn=α+dα(tn-tα) in accordance with the information, and outputs the calculated estimated dataαn to a processing part 7.
