PURPOSE:To tabulate record tabulation data classified by every category record only by adding simple circuit configuration by reading out the record tabulation data classified by every category tabulated in an accumulative register by an adder circuit and erasing the content of the accumulative register when noncoincidence between both data is obtained by a comparator. CONSTITUTION:The comparator 4-8 compares the category data taken out newly from a category masking circuit 4-7 with the one of preceding record stored in a holding register 4-9. When the noncoincidence is obtained between them by the comparator 4-8 as a result, a clear signal is supplied to the accumulative register 4-2, and a write signal to a storage part 4-5 for output. In such a case, the value of the accumulative register 4-2 is cleared after the value of the accumulative register 4-2 is written on the storage part 4-5 for output. Thereby, it is possible to tabulate the data targeted to tabulate in each record classified by every category by intercepting CPU processing only by adding the simple circuit configuration. |
