EE Times reports ARM is working on extensions to the ARMv7 architecture to support virtualization and 40-bit addressing. These new technologies should aid ARM to get into the server market.
The extensions aim to serve a variety of new and existing markets from mobile devices to servers.
The lack of 64-bit addressing is one of the barriers to a new initiative bringing ARM cores to servers. The 40-bit addressing will ease but not eliminate that concern.
The virtualization extensions will create a new privilege level for hypervisors. It supports two-stage address translation for operating system OS and hypervisor levels and supports ARM TrustZone security extensions.
