New Ways To Scale Performance

Immense amounts of data are being collected today in areas such as meteorology, geology, astronomy, quantum physics, fluid dynamics, and pharmaceutical research. Exascale computing (the execution of a billion billion floating point operations, or exaFLOPs, per second) is the target that many HPC systems aspire to over the next 5 to 10 years. In addition, advances in data analytics and areas su... » read more

Thermal And Power Considerations In Designing For The Developing World

Engineers designing for emerging markets confront fascinating challenges. Take data centers for developing societies. Most of these systems are in remote locations, exposed to the elements, with limited power, save for the sun. How do you deal with rain, rust, durability? How do you prevent members of the animal kingdom sauntering by and chewing on your system? These are some of the intri... » read more

Cloud 2.0

Corporate data centers are reluctant adopters of new technology. There is too much at stake to make quick changes, which accounts for a number of failed semiconductor startups over the past decade with better ideas for more efficient processors, not to mention rapid consolidation in other areas. But as the amount of data increases, and the cost of processing that data decreases at a slower rate... » read more

The Interconnect Bottleneck

With communications playing a crucial role in the design and performance of multi-core SoCs, various interconnect structures have been proposed as promising solutions to simplify and optimize SoC design. However, sometimes things don’t go as planned and the interconnect becomes the bottleneck. “Under high utilization cases the DRAM will be over-constrained with requests from all the a... » read more

Porting To ARM 64-Bit

Why 64-bit? It seems that is a question with many answers! For some, it will be the need to address more than 4GB of memory, for others the need for wider registers and greater accuracy of 64-bit data processing, for still others the attraction of a larger register set. Whatever your reason for looking to move to 64-bit, it is likely that you will have a body of legacy software which will ne... » read more

New Challenges, New Name

As you’ll notice today, we’ve changed our name from Low Power Engineering to Low-Power/High-Performance Engineering. We don’t take name changes lightly—we've been discussing this in depth with readers, sponsors, and researchers for the past six months. The almost universal conclusion is there is a big shift underway in the semiconductor industry today, and our new logo is a better refle... » read more
