Webinar: Turnkey Bluetooth True Wireless Stereo Earbuds and Speakers

Webinar: Turnkey Bluetooth True Wireless Stereo Earbuds and Speakers
by Bernard Murphy on 12-01-2018 at 7:00 am

When we were first introduced to earbuds, in-ear speakers connected through thin wires to your phone (and earlier portable music devices), they seemed pretty convenient for private entertainment at work, while walking, exercising, doing almost anything. Until we started to realize those long dangly wires weren’t ideal. They… Read More


On-Chip Networks at the Bleeding Edge of ML

On-Chip Networks at the Bleeding Edge of ML
by Bernard Murphy on 11-29-2018 at 7:00 am

I wrote a while back about some of the more exotic architectures for machine learning (ML), especially for neural net (NN) training in the data center but also in some edge applications. In less hairy applications, we’re used to seeing CPU-based NNs at the low end, GPUs most commonly (and most widely known) in data centers as the workhorse… Read More


Mesh Networks, Redux

Mesh Networks, Redux
by Bernard Murphy on 09-27-2018 at 7:00 am

It isn’t hard to understand the advantage of mesh networking (in wireless networks). Unlike star/tree configurations in which end-points connect to a nearby hub (such as phones connecting to a conventional wireless access point), in a mesh nodes can connect to nearest neighbors, which can connect to their nearest neighbors… Read More


A Fresh Idea in Differential Energy Analysis

A Fresh Idea in Differential Energy Analysis
by Bernard Murphy on 09-06-2018 at 7:00 am

When I posted earlier on Qualcomm presenting with ANSYS on differential energy analysis, I assumed this was just the usual story on RTL power estimation being more accurate for relative estimation between different implementations. I sold them short. This turned out to be a much more interesting methodology for optimizing total… Read More


Architecting an ML Design

Architecting an ML Design
by Bernard Murphy on 08-14-2018 at 7:00 am

Discussion on machine learning (ML) and hardware design has been picking up significantly in two fascinating areas: how ML can advance hardware design methods and how hardware design methods can advance building ML systems. Here I’ll talk about the latter, particularly about architecting ML-enabled SoCs. This approach is … Read More


Webinar: Differential Energy Analysis for Improved Performance/Watt in Mobile GPU

Webinar: Differential Energy Analysis for Improved Performance/Watt in Mobile GPU
by Bernard Murphy on 07-31-2018 at 7:00 am

May want to listen up; Qualcomm are going to be sharing how they do this. There is a constant battle in designing for low power; you don’t accurately know what the power consumption is going to be until you build it, but by the time you’ve built it, it’s too late to change the design. So you have to find methods to estimate power early on,… Read More


Platform ASICs Target Datacenters, AI

Platform ASICs Target Datacenters, AI
by Bernard Murphy on 07-17-2018 at 7:00 am

There is a well-known progression in the efficiency of different platforms for certain targeted applications such as AI, as measured by performance and performance/Watt. The progression is determined by how much of the application can be run with specialized hardware-assist rather than software, since hardware can be faster… Read More


Dragonfly-NB2: You Can Have It All in Your IoT Device

Dragonfly-NB2: You Can Have It All in Your IoT Device
by Bernard Murphy on 07-03-2018 at 7:00 am

I wrote last month about CEVA’s Dragonfly-NB1 platform, a single-chip IoT solution supporting narrow-band cellular communication; this can meet aggressive total solution price-targets for high-volume deployment, long-range access and the low-power needed for 10+ year battery lifetimes. That solution, based on Release… Read More


Design for Power: An Insider View

Design for Power: An Insider View
by Bernard Murphy on 06-28-2018 at 7:00 am

The second keynote at Mentor’s U2U this year was given by Hooman Moshar, VP of Engineering at Broadcom, on the always (these days) important topic of design for power. This is one of my favorite areas. I have, I think, a decent theoretical background in the topic, but I definitely need a periodic refresh on the ground reality from the… Read More


Low Power Verification Shifting Left

Low Power Verification Shifting Left
by Bernard Murphy on 05-08-2018 at 11:00 pm

I normally think of shift left as a way to move functional verification earlier in design, to compress the overall design cycle. But it can also make sense in other contexts, one particularly important example being power intent verification.

If you know anything about power intent, you know that it affects pretty… Read More
