Address translation mechanism.

摘要

A dynamic address translation mechanism uses a single translation look aside buffer (TLB) 30 for pages of various sizes. The single TLB is supported by a small amount of special hardware. This hardware includes logic for detecting a page size prior to translation and generating a mask 36. The logic selects a set of virtual address bits for addressing the entries in the TLB. Parts of the virtual address are masked and merged with the address read out of the TLB to form the real address 37. <IMAGE>
