Subsystem IP: The Implications Reach Beyond the Chip

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

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 […]

OK, 4K Ultra-High Definition TV, Where is My Content?

OK, 4K Ultra-High Definition TV, Where is My Content?

You lusted after the early demonstration units. You watched with growing anticipation as more vendors announced products. As prices began to fall, you laid your plans. And then at the perfect moment, you pounced! A 4K ultra-high definition (UHD) TV, with a screen the size of a dining table, a two-page list of features, and […]

When Your Embedded Processor Runs Out of Steam, Try Parallelism

When Your Embedded Processor Runs Out of Steam, Try Parallelism

The scenario is becoming increasingly familiar. You have a working embedded design, perhaps backed by years of deployment with customers and hundreds of thousands of lines of debugged code. Along comes marketing with a new set of performance specifications, or R/D with a new computer-crushing algorithm. Your existing CPU family just can’t handle it. At […]

Is the System on Chip Coming Apart?

Is the System on Chip Coming Apart?

Arguably it is, in some circumstances. This disintegration can take any of several paths—some of which wind deep into the promising yet problematic technology of 2.5D packaging, while others lead back to the seemingly archaic landscape of separate chips on a board, albeit with very unarchaic interconnect technology. The only accurate map for these varied […]
