Abstract

In many systems, Virtual Address Translation (VAT) and key checking have been regarded as an overhead to any memory access. With the use of+ today's large memory chips with multiplexed address lines, this is no longer true. Since part of the Virtual Address corresponds directly to the Real Address, it can be used to start addressing main memory while translation and checking are performed on the other bits.
