Systems and methods for accessing a unified translation lookaside buffer

A unified translation lookaside buffer (TLB), comprising:

• a page size cache mapping virtual addresses to page size;
• a second level TLB mapping virtual addresses and page sizes to physical addresses;
• and
• a unified TLB access component to search the page size cache with an input virtual address to identify a page size, and to look up a physical address translation of the virtual address in the second level TLB using the page size.

A computer system comprising:

• a processor;
• a memory;
• a memory management unit (MMU) coupled to the processor and the memory, the MMU to access memory in response to requests from the processor;
• and
• a unified translation lookaside buffer (TLB) to convert virtual addresses provided by the MMU into physical addresses in the memory, the unified TLB including a page size cache mapping virtual addresses to page size, a second level TLB mapping virtual addresses and page sizes to physical addresses, and a unified TLB access component to search the page size cache with an input virtual address to identify a page size, and to look up a physical address translation of the virtual address in the second level TLB using the page size.
