Method and apparatus for implementing virtual memory having multiple selected page sizes

An apparatus for implementing virtual memory having multiple selected page sizes comprising:

• a virtual address;
• the virtual address including a map index and a frame offset;
• selector means for receiving the virtual address frame offset and the multiple selected page sizes for generating a selector offset and a selector index;
• said selector means includes means for storing a plurality of predetermined page boundaries;
• frame map table means for indexing the virtual address map index and the generated selector index and generating a base address;
• and
• means for adding the frame map table means generated base address and the generated selector offset and providing a physical address.

A method for implementing virtual memory having multiple selected page sizes comprising the steps of:

• receiving a virtual address;
• said virtual address including a map index and a frame offset;
• generating a selector offset and a selector index utilizing said virtual address frame offset and a page size array;
• said step of generating said selector offset and said selector index utilizing said virtual address frame offset and said page size array further includes the step of generating a selector limit utilizing said virtual address frame offset and said page size array;
• indexing a frame map table with both the virtual address map index and said generated selector index and generating a base address;
• and
• adding said generated base address and said generated selector offset for providing a physical address.
