High performance embedded processors are equipped with the Translation Look-aside Buffer (TLB) which forms the key ingredient to efficient and speedy virtual memory management. The TLB though small, is frequently accessed, and therefore not only consumes significant energy, but also is one of the important thermal hot-spots in the processor. Among the many circuit and microarchitectural techniques proposed to reduce TLB power consumption, the Use-Last TLB is one very efficient technique in which power is consumed only when different pages are accessed in succession, i.e., when there is a page-switch.
