Abstract
PURPOSE: To improve the effective speed of an information processing unit by causing a substitution mechanism to substitute information accomodated in high- speed and small-capacity memory to reduce the information transfer frequency to the high-speed and small-capacity memory from a main memory.
CONSTITUTION: Precedence determination mechanism 10 determines a residual precedence in unit 4 for every information transferred from a low-speed large- capacity memory to high-speed small-capacity memory 4, and substitution control mechanism 14 performs the substitution control of information accomodated in unit 4. Here, the precedence is determined for every information, which is to be accomodated in unit 4, by residual precedence determination mechanism 11 in unit 4 on a basis of information of the frequency where information is accessed by the logical operation processing part. Then, mechanism 14 regards precedence determination information as a part of substitution control information of information in unit 4 to substitute information accomodated in unit 4. Consequently, the residual ratio in unit 4 of information required by the logical operation part is improved, and the information transfer frequency from main memory 1 to unit 4 is reduced. As a result, the effective speed of an information processing unit can be improved.
