Intel Trusted Execution Technology for safer computing is a versatile set of hardware extensions to Intel processors and chipsets that enhance the digital office platform with security capabilities such as measured launch and protected execution. It enables an environment where applications can run within their own space, protected from all other software on the system. Intel Virtualization Technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) and Itanium processor (VT-i) virtualization adding new support for I/O-device virtualization. Intel VT-d can help end users improve security and reliability of the systems and also improve performance of I/O devices in virtualized environments. Intel Virtualization Technology (VT-x) allows one hardware platform to function as multiple virtual platforms. It offers improved manageability by limiting downtime and maintaining productivity by isolating computing activities into separate partitions. Intel 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms when combined with supporting software.¹ Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.
