专利汇可以提供High-speed buffer memory control system专利检索,专利查询,专利分析的服务。并且PURPOSE: To improve the performance of the system by equipping an indicator that indicates the operation mode of an information processor and by exercising control so that access areas is a high-speed buffer can change according to a mode that the indicator indicates.
CONSTITUTION: When combinational circit 16 satisfies privilege-mode.pure-program.instruction-read (symbol.is AND), the bit of the access address of the high-speed buffer memory is set to 1 according to an operation mode indicated by indicator 15 and directory part 2, memory part 3 and directory control part 5 of the high-speed buffer memory have areas (b), higher priority parts, accessed. when the above-mentioned AND is not satisfied, the bit of the access address of the high- speed buffer memory is set to 0 respective parts 2, 3 and 5 of the high-speed buffer memory have areas (a), low priority parts, accessed. There is no need to clear areas (b) of the high-speed buffer memory except in system initialization. Therefore, the performance of the system can be improved.
