Abstract

PURPOSE: To effectively utilize the memory by comparing an input data with the previous record as to each record, and omitting and outputting the same data of the same place, in the data processing system for compressing an input data.
CONSTITUTION: A data which is input is held in the data register 2 in 1 byte unit, and it is compared in order as to the same digit with the data of 1 record portion stored in the record buffer register 1, by the comparator 3. In case when they are inconsistent, an inconsistency signal is output so that only the data which has caused inconsistency is written into the data buffer register 6. Accordingly, in case when an input data is input repeatedly, the input data is compressed remarkably, and is written into the memory 8.
