Embedded Computing Needs Hardware-Based Security

CATEGORIES : Embedded system/AUTHOR : Ron Wilson

Embedded systems are in a profound transition: from physically isolated, autonomous devices to Internet-connected, accessible devices. Designers are learning—often to their dismay—that the mutation requires far more than just gluing a network interface onto the bus and adding an Internet Protocol stack. In many ways, these Internet-aware designs are coming to look less like traditional […]

Embedded Computing on the Edge

CATEGORIES : Embedded system, IoT/AUTHOR : Ron Wilson

Embedded computing has passed—more or less unscathed—through many technology shifts and marketing fashions. But the most recent—the rise of edge computing—could mean important new possibilities and challenges. So what is edge computing (Figure 1)? The cynic might say it is just a grab for market share by giant cloud companies that have in the past struggled […]

Look Sharp: The IoT is Watching

CATEGORIES : Embedded system, IoT/AUTHOR : Ron Wilson

The Internet of Things (IoT) is about to change profoundly the design of embedded systems—but probably not in the way you are thinking. The change will begin not in silicon or in algorithms but in business models. Yet it will quickly permeate every aspect of embedded design. Early warnings of the shift began several years […]

Blockchains Unchained

CATEGORIES : Embedded system, IoT/AUTHOR : Ron Wilson

It first came to our attention as the plausible-sounding but obscure data structure that made Bitcoin unhackable. Then some people lost a lot of money in attacks on Bitcoin exchanges. But before the cyberspace version of yellow crime-scene tape could come down, blockchain was back. Exonerated for the bitcoin fiascos, blockchains were now being researched […]

Is that Drone the Sound of Progress?

CATEGORIES : Embedded system/AUTHOR : Ron Wilson

By now, thanks to the attentions of marketing writers and news reporters, the word “drone” is overloaded with meanings. Let’s set aside traditional senses: a low-frequency, continuous sound; a male bee; an unsounded string on a musical instrument. We are interested in aircraft. Somehow in the mid-20th century the military began calling unmanned target aircraft […]
