Secure Embedded Systems: Digging for the Roots of Trust

Many embedded designs absolutely have to work right. A malfunction could do unacceptable harm to persons or property. Until recently, this requirement has been addressed through careful design and hardware reliability: if the software and the logic are right and there are no hardware failures, the system will work. But today we live in the […]

The FinFET Revolution is Changing Computer Architecture

The arrival of FinFETs, starting in the 20 nm CMOS logic process node, has been justly credited with saving Moore’s Law. Just as our ability to continue scaling planar MOSFETs began to come apart, the FinFET’s vastly superior channel control came to the rescue, taming leakage currents and opening the way to continued voltage scaling. […]

Sorting Out Embedded Vision Systems

Papers at this year’s Embedded Vision Summit suggested the vast range of ways that embedded systems can employ focused light as an input, and the even vaster range of algorithms and hardware implementations they require to render that input useful. Applications range from simple, static machine vision to classification and interpretation of real-time, multi-camera video. […]

Subsystem IP: The Implications Reach Beyond the Chip

The appearance of subsystem-scale intellectual property (subsystem IP) cores a few years ago triggered a glacial shift in system-on-a-chip (SoC) design: slow, inexorable, but shoving before it a mound of unintended consequences. As cell-based SoCs and even FPGAs incorporating subsystem IP appear in real systems, we are seeing that those consequences extend even beyond the […]

Rethinking the Internet of Things

As the Internet of Things (IoT) cements itself into place as the mandatory next big thing for 2015, more systems architects are taking a hard look at its underlying concepts. As they look, these experts are asking some hard questions about simplistic views of the IoT structure: the clouds of sensors and actuators attached to […]
