11 Ways To Reduce AI Energy Consumption


As the machine-learning industry evolves, the focus has expanded from merely solving the problem to solving the problem better. “Better” often has meant accuracy or speed, but as data-center energy budgets explode and machine learning moves to the edge, energy consumption has taken its place alongside accuracy and speed as a critical issue. There are a number of approaches to neural netw... » read more

Mapping Heat Across A System


Thermal issues are becoming more difficult resolve as chip features get smaller and systems get faster and more complex. They now require the integration of technologies from both the design and manufacturing flows, making design for power and heat a much broader problem. This is evident with the evolution of a smart phone. Phones sold 10 years ago were very different devices. Functionality ... » read more

Modernizing Audio Codec Industry Standards For Enhanced Power Savings And Performance


Mobile phones have become a necessity, and we all use them to talk, play, communicate, and manage many aspects of our lives. While you may have an iPhone, your friends might have an Android phone  from one of several vendors. They all look and feel different, yet you can seamlessly talk with your friends. How is that possible? While they are different in some ways, they are similar in many oth... » read more

Blog Review: May 12


Cadence's Claire Ying points to major changes in PCIe 6.0 as PAM4 signaling replaces NRZ to help double bandwidth, Forward Error Correction helps maintain data integrity, and various improvements are made to power consumption. Synopsys' Samantha Beaumont argues that automotive sensors are a major potential attack point and addresses some of the key areas of sensor vulnerability and the chall... » read more

Developers Turn To Analog For Neural Nets


Machine-learning (ML) solutions are proliferating across a wide variety of industries, but the overwhelming majority of the commercial implementations still rely on digital logic for their solution. With the exception of in-memory computing, analog solutions mostly have been restricted to universities and attempts at neuromorphic computing. However, that’s starting to change. “Everyon... » read more

IC Security Threat Grows As More Devices Are Connected


Designing for security is beginning to gain traction across a wider swath of chips and systems as more of them are connected to the Internet and to each other, sometimes in safety- and mission-critical markets where the impact of a cyber attack can be devastating. But it's also becoming more difficult to design security into these systems. Unlike in the past, connectivity is now considered e... » read more

Battle Brewing Over Automotive Display Protocols


Displays are multiplying in new and future automobiles. That means a lot more display data moving around the vehicle and traveling some distance between sensor and processor. While existing protocols can handle some of the new duties, new protocols also are being developed specifically for this application. “Automotive displays are proliferating, increasing in numbers and in pixel densi... » read more

Using In-Design Analysis Flows To Resolve Signal Integrity Issues


In today’s ever-shrinking IC package design cycles, it is almost imperative that we catch and correct routing issues as early as possible, which makes simulation an integral part of the design cycle. Layout engineers want a quick and accurate way to find out the layout mistakes by looking at the changing impedance values and high coupling due to nearby signals. Unfortunately, layout engineers... » read more

Blog Review: May 5


Arm's William Wang considers how to increase the performance and programmability of persistent applications through using battery to protect the on-chip volatile cache hierarchy. Cadence's Paul McLellan finds that ransomware is getting more sophisticated, and more difficult to eradicate and defend against, with potentially life-threatening consequences. Synopsys' Jonathan Knudsen digs int... » read more

Steep Spike For Chip Complexity And Unknowns


Cramming more and different kinds of processors and memories onto a die or into a package is causing the number of unknowns and the complexity of those designs to skyrocket. There are good reasons for combining all of these different devices into an SoC or advanced package. They increase functionality and can offer big improvements in performance and power that are no longer available just b... » read more
