System and method for performing address translation in a computer system

摘要

An address translation unit generates a physical address for access to a memory from a virtual address using either a translation lookaside buffer or a segmentation buffer. If the virtual address falls within a predetermined range, the address translation unit will use the segmentation buffer to generate the physical address. Upon generation of the physical address, the memory will either receive data from or provide data to a processor in accordance with the instructions being processed by the processor.
