Virtual address bypassing using local page mask |
摘要 |
A cache with a translation lookaside buffer (TLB) that reduces the time required for retrieval of a physical address from the TLB when accessing the cache in a system that supports variable page sizing. The TLB includes a content addressable memory (CAM) containing the virtual page numbers corresponding to pages in the cache and a random access memory (RAM) storing the physical page numbers of the pages corresponding to the virtual page numbers in the CAM. The physical page number RAM stores a page mask along with the physical page numbers, and includes local multiplexers which perform virtual address bypassing of the physical page number when the page has been masked.
