AMD Touts Presidio
“Presidio is an AMD program focused on advancing PC and server security technology,” AMD’s spokesman Phil Hughes told X-bit labs.
The representative remained tight-lipped over the details concerning the technology and did not reveal any direction of Presidio. He declined to comment whether there are any links between Presidio, Intel’s LaGrande technology and Microsoft’s Longhorn operating system.
Earlier this year Sunnyvale, California-based AMD incorporated so-called non-execute bit into its chips. The capability protects certain system memory data regions from insertion and execution of potentially harmful code, that is also referred as NX-bit, eXecute Disable (XD) or AntiVirusNX Technology and works only in conjunction with Windows XP operating systems that feature Service Pack 2.
