Hubs Become Central to the IoT

Even before real systems are widely deployed, the Internet of Things (IoT) is rushing into a period of rapid evolution. Early—and, frankly, simplistic—ideas about IoT architecture are giving way to more nuanced views, often based on analysis of data flows and on hard questions of why the IoT really matters. The result will be new […]


Flash Triggers a Revolution

Two strong currents of technology change are surging across the data center, sweeping away conventional thinking and leaving behind profoundly changed software, memory, and storage architectures. One current, rising from the largely unexplored region of neural networks, is altering the way applications access data. The other, springing from the depths of semiconductor physics, is dissolving […]

Power and Complexity: Welcome to AMP

Asymmetric multiprocessing (AMP) is on the short list to be the technology acronym of the year for 2016. But what is it, exactly, and why would you want any? More usefully, what are the considerations and challenges in implementing AMP in an embedded system? Let’s begin with definitions. A symmetric multiprocessing (SMP) system is one […]

Darwin Comes to Cable

Pause a moment, if you will, to consider the plight of the oft-reviled cable television providers. At their roots, these companies operated essentially unidirectional networks of coaxial cable for distributing analog video signals to homes. That was then. And this is now: those original co-ax networks have evolved into asymmetric, bidirectional digital data networks offering […]
