PURPOSE:To input a large quantity of data at a high speed, and also, to more strictly detect an error by providing an error deciding means for comparing and deciding the present data in a buffer of a processing object with the future data and the past data. CONSTITUTION:By a switch S2, the present data 11 having possibility that an error occurs in a buffer 2a of a processing object, and also, having such a quality as a monotone increased or a monotone decrease occurs in a normal case is led to an error deciding means 4 and a data processing means 3. Also, a switch S3 leads the future data 13 in a data inputted buffer 2b to the mans 4. In the means 4, the data 11 is compared with the data 12 and the data 13, whether the data 11 is an error or not is decided, and a decision result 7 is outputted to the means 3. In the means 3, based on the result 7, a processing of the buffer 2a is executed. Subsequently, at the time point when input data 5 completes an input to the buffer 2b through a switch S1, and the processing of the buffer 2a of the means 3 is completed, probability of an error detection is improved by switching the switches S1-S3 to the opposite side and repeating the processing. |
