Abstract
A data control device capable of high-quality, high-efficiency control for speeding up data processing, thus permitting improvement of the throughput of a system. Attribute analyzing unit analyzes an attribute of data, and a main memory stores setting information of the data in a region corresponding to the attribute. A highway cache memory stores the data, and also receives and transmits the data on a highway. A processor performs an operation on the data in accordance with the setting information. A data cache memory is interposed between the processor and the main memory and stores the setting information.
