AUSTIN, Texas — A systematic analysis of power usage in microprocessors could help lower the energy consumption of both small cellphones and giant data centers, report computer science professors from The University of Texas at Austin and the Australian National University.

Their results may point the way to how companies such as Google, Apple, Intel and Microsoft can make software and hardware that will lower the energy costs of very small and very large devices. (more…)

The operating system (OS) is the backbone of your computer. If the OS is compromised, attackers can take over your computer – or crash it. Now researchers at North Carolina State University have developed an efficient system that utilizes hardware and software to restore an OS if it is attacked.

At issue are security attacks in which an outside party successfully compromises one computer application (such as a Web browser) and then uses that application to gain access to the OS. For example, the compromised application could submit a “system call” to the OS, effectively asking the OS to perform a specific function. However, instead of a routine function, the attacker would use the system call to attempt to gain control of the OS. (more…)
