PURPOSE:To fetch and process input data of a software after the input data are annihilated and to improve the processing capacity of the software, by restoring the annihilated input data at a software by data outputted from a gate circuit. CONSTITUTION:The leading edge and trailing edge of input data A are differentiated at a beading edge and trailing edge changing state differentiation circuits 1 and 2, and these resulted data B, C are stored in leading edge and trailing edge changing state storing FF circuits 5, 6, respectively. Moreover, the changing state of the data A is counted by a counting circuit 4 and the counted data D are added to a gate circuit 7 and, at the same time, a read signal G is added to a read signal trailing edge changing state differentiation circuit 3, and a reset signal H is detected. The signal H is added to the circuits 5 and 6 and leading edge and trailing edge changing state differentiated data E, F are added to the circuit 7. Moreover, the signals A and G are added to the circuit 7, and the input data of a software is fetched and processed after the input data are annihilated, and input data are restored at the software. Thus the processing capacity of the software is improved. |
