Abstract
Microprocessor architecture for an address translation unit which provides two levels of cache memory management is described. Segmentation registers and an associated segmentation table in main memory provide a first level of memory management which includes attribute bits used for protection, priority, etc. A second page cache memory and an associated page directory and page table in main memory provide a second level of management with independent protection on a page level. eyboard
