Abstract

PURPOSE:To prevent the drop-out of effective data for overflow as much as possible, by rewriting contents of an area, where data of the lowest priority level is written, with input data if a buffer memory has no idle area. CONSTITUTION:Priority level data PRO indicating the priority of data is attached to input data 7, and respective memory areas U1-UN in a buffer memory 8 are provided with areas where data PRO should be written. Consequently, data 7 is written in the area where data of the lowest priority level is written. At this time, data PRO is rewritten. In the output side, the priority level of data is discriminated by data PRO, and data are read out in order from data of the highest priority level. Thus, the drop-out of data for overflow of the memory 8 is minimized to process data in order from data of the highest priority level.
