Execution Unit

Execute Disable Bit

The Execute Disable bit allows memory to be marked as executable or non-

executable, when combined with a supporting operating system. If code 

attempts to run in non-executable memory the processor raises an error to the 

operating system. This feature can prevent some classes of viruses or worms 

that exploit buffer overrun vulnerabilities and can thus help improve the overall 

security of the system. See the Intel

Developer's Manuals for more detailed information.

Intel

®

 Virtualization Technology (Intel

®

 VT) for Directed I/O. Intel VT-d is a 

hardware assist, under system software (Virtual Machine Manager or OS) 

control, for enabling I/O device virtualization. Intel VT-d also brings robust 

security by providing protection from errant DMAs by using DMA remapping, a 

key feature of Intel VT-d.

LVDS

Low Voltage Differential Signaling. A high speed, low power data transmission 

standard used for display connections to LCD panels.

NCTF

Non-Critical to Function. NCTF locations are typically redundant ground or non-

critical reserved, so the loss of the solder joint continuity at end of life conditions 

will not affect the overall product functionality.
