Intel Corporation is reported to add "J" letter to the model number of its microprocessors that support XD technology. The chips that feature security enhancements to be unveiled later this year are said to be available at different speed-bins, for different platforms and at different price-points.
All Intel Pentium 4, Pentium M and Celeron D processors that sport the so-called XD technology will contain "J" latter in the product model number, e.g., Pentium 4 560J, AnandTech web-site reports. The XD technology aka Execute Disable Bit is a certain flag that determines whether instructions can be executed from the page. The feature may add some more security to current PCs. The web-site believes that eventually Celeron D microprocessors in LGA775 packaging will also get the support for the XD technology. More surprisingly, the Pentium M are also said to feature the security enhancement.
