<p>Efficient high-speed data control with high quality is carried out to increase system throughput. Attribute analysis means (20) analyzes the attributes of data. A main memory (30) stores information on data setting in an area corresponding to the attributes. Highway cache memories (11-1 to 11-n) store data and transfers data on highways. Processors (12-1 to 12-n) process data according to the information on data setting. Data cache memories (13 1 to 13-n) are arranged between the processors (12-1 to 12-n) and the main memory (3O) to store the information on data setting.</p>
