Bridging The Rift Between Software And Hardware
By Ed Sperling - 12 Jul, 2012 - Comments: 0

By Ed Sperling As more computing is done on mobile devices rather than desktops, the idea of what constitutes good application software is changing. This addresses the key reason why some of advanced power-saving features built into chips were not utilized by software in the past. Unless the operating systems were specifically written for mobile devices, such as Android and iOS, the real f... » read more

Why PCs And Servers Aren’t Going Away
By Ed Sperling - 22 Mar, 2012 - Comments: 0

By Pallab Chatterjee With the rise of mobile appliances, smart phones and tablets, there has been a lot of discussion about the place for PCs, servers, embedded processors and networks. A number of companies have claimed they will rule the world of computing and there will no room for others. Reality seems to be somewhat different, however. The mobile end point devices—smart phones, table... » read more

A Warmer Reception

For years data center operations managers have been complaining that they can no longer cool racks of servers enough to bring them down to the maximum temperature. The increasing density of chips, thinner servers packed more tightly together and the usual current leakage have become so bad that it’s impossible to blow enough cool air through the server cabinets. In fact, it’s gotten to the ... » read more

Anatomy Of A (Better) Gaming Platform

By Pallab Chatterjee Microsoft’s third-generation Xbox360 engine uses a 45nm silicon on insulator (SOI) process—and a new architecture. The original design was on 90nm and then migrated to 65nm. In both of these cases the fundamental architecture of the system remained the same—a CPU (central processing unit) chip, a GPU (graphics processing unit) chip, and memory management chip for ... » read more

He also is the... » read more

Writing Application Software Directly To The Metal
By Ed Sperling - 13 Mar, 2009 - Comments: 0

By Ed Sperling How necessary is an operating system? That question would have been considered superfluous a decade ago, possibly even blasphemous and career-limiting. But it now is beginning to surface in low-power discussions, particularly in compute-intensive applications where performance and power are both critical. General-purpose operating systems constantly call on the processor fo... » read more
