Sonics opens new strategy for SoC energy processing

Sonics opens new strategy for SoC energy processing

Back in February when we shared the Sonics philosophy on the ICE-Grain Power Architecture for hardware-based SoC power management, I speculated we’d know more by DAC 2016. Sonics is hitting the road with a new live seminar coming to Silicon Valley this month and Austin during DAC – and the news is big.… Read More


Optimizing memory scheduling at integration-level

In our previous post on SoC memory resource planning, we shared 4 goals for a solution: optimize utilization and QoS, balance traffic across consumers and channels, eliminate performance loss from ordering dependencies, and analyze and understand tradeoffs. Let’s look at details on how Sonics is achieving this.… Read More


4 goals of memory resource planning in SoCs

4 goals of memory resource planning in SoCs

The classical problem every MBA student studies is manufacturing resource planning (MRP II). It quickly illustrates that at the system level, good throughput is not necessarily the result of combining fast individual tasks when shared bottlenecks and order dependency are involved. Modern SoC architecture, particularly … Read More

Apple’s recent bout with ‘Batterygate’ highlighted just how important dynamic power management can be. Our last Sonics update looked at using their NoC to manage power islands; this time, we look at their research progress on architectural measures for power management.… Read More

For decades, tracing back to the days of Deming, the way to tackle complex engineering problems has been the pareto chart. Charting conditions and their contribution to the problem leads to mitigation priorities.

In the case of SoC power management, the old school pareto chart said the processor core was the biggest power hog and… Read More


Finding under- and over-designed NoC links

Finding under- and over-designed NoC links
by Don Dingee on 11-24-2015 at 12:00 pm

When it comes to predicting SoC performance in the early stages of development, most designers rely on simulation. For network-on-chip (NoC) design, two important factors suggest that simulation by itself may no longer be sufficient in delivering an optimized design.

The first factor is use cases. I think I’ve told the story … Read More


To err is runtime; to manage, NoC

To err is runtime; to manage, NoC

Software abstraction is a huge benefit of a network-on-chip (NoC), but with flexibility comes the potential for runtime errors. Improper addresses and illegal commands can generate unexpected behavior. Timeouts can occur on congested paths. Security violations can arise from oblivious or malicious access attempts.

Runtime… Read More


What NoCs with virtual channels really do for SoCs

What NoCs with virtual channels really do for SoCs
by Don Dingee on 10-05-2015 at 7:00 am

Most of us understand the basic concept of a virtual channel: mapping multiple channels of traffic, possibly of mixed priority, to a single physical link. Where priority varies, quality of service (QoS) settings can help ensure higher priority traffic flows unimpeded. SoC designers can capture the benefits of virtual channels… Read More

If I grab 10 technologists and ask what are the most important issues surrounding the Internet of Things today, one of the popular answers will be “security.” If I then ask them what IoT security means, I probably get 10 different answers. Encryption. Transport protocols. Authentication. Keying. Firewalls. Secure boot. Over-the-air… Read More
