PURPOSE: To make it possible to increase the number of processing signals without increasing the quantity of hardware by reading out stored logic data without turning off a power supply, substituting the read data for logic already set up in an arithmetic means and resetting the substituted data. CONSTITUTION: A logical operation element 102 can substitute new logic for logic already set up in its inside and reset the substituted logic, plural storage devices 104, 105 are prepared for resetting data in the element 102 and the new logic data are stored in these devices 104, 105. One of the new logic data stored in the devices 104 and 105 is selected and read out by a control circuit 106 and the new logic data read out of the device 104 or 105 can be substituted for the logic set up in the element 102 and reset without turning off the power supply of the element 102. When an input signal is inputted to the element 102 through respective delay circuits 103, a signal processed based upon the new logic is outputted from the element 102. |
