Abstract
For extracting a unit data block of the lowest priority from a plurality of unit data blocks stored in a buffer memory of large capacity, the unit data blocks are divided into set blocks, each comprising a predetermined number of unit data blocks, and priority levels of the set blocks are determined to extract one of them. At the same time, priority levels of the predetermined number of unit data blocks making up each set block are determined to extract one of them. One unit data block is extracted by a combination of the extracted set block with the unit data blocks extracted from the respective set blocks. In this manner, one of many unit data blocks is extracted by using a small number of bits.
