Abstract
A translation buffer is provided in parallel to a translation lookaside buffer (TLB) to cache translations between intermediate physical addresses (IPAs) and pointers for entries in the TLB corresponding to the IPAs. The pointers can be used to identify and invalidate only certain entries in the TLB as compared to invalidating the whole TLB.
