Closing The Power Integrity Gap
By Ann Mutschler - 19 Oct, 2016 - Comments: 0

Voltage drop has always been a significant challenge. As far back as 130nm, specialist tools were being used to ensure that enough local decoupling capacitance (decap) cells were inserted in addition to larger decaps implemented around the SoC. But advanced nodes are complicating matters and further increasing complexity. These technological challenges, which underlie the power, performance ... » read more

Side-Channel Attacks Make Devices Vulnerable
By Brian Bailey - 17 Oct, 2016 - Comments: 0

As the world begins to take security more seriously, it becomes evident that a device is only as secure as its weakest component. No device can be made secure by protecting against a single kind of attack. Hypervisors add a layer of separation between tasks making sure that one task cannot steal secrets from another. Protection of the JTAG port is necessary to prevent access underneath the h... » read more

Power Limits Of EDA
By Brian Bailey - 13 Oct, 2016 - Comments: 3

Power has become a major gating factor in semiconductor design. It is now the third factor in design optimization, along with performance, and is almost becoming more important than area. But there are limits to the amount of help that [getkc id="7" kc_name="EDA"] can provide with [getkc id="106" kc_name="power optimization"]. Power is not just an optimization problem. It is a design problem... » read more

Betting On Power And Deep Learning
By Ed Sperling - 13 Oct, 2016 - Comments: 0

Jim Hogan, managing partner of Vista Ventures, sat down with Semiconductor Engineering to talk about what investments deliver the biggest returns, how quickly, and why there are so few investors in some big growth areas. What follows are excerpts of that conversation. SE: What are you investing in these days and why? Hogan: I have about 15 active deals right now. I generally invest in thi... » read more

Seeing The Future Of Vision
By Jeff Dorsch - 13 Oct, 2016 - Comments: 0

Vision systems have evolved from cameras that enable robots to “see” on a factory floor to a safety-critical element of the heterogeneous systems guiding autonomous vehicles, as well as other applications that call for parallel processing technology to quickly recognize objects, people, and the surrounding environment. Automotive electronics and mobile devices currently dominate embedded... » read more

Getting The Power/Performance Ratio Right
By Ann Mutschler - 13 Oct, 2016 - Comments: 0

Getting to market quickly means determining as soon as possible if a concept for a new design will work or not, particularly where power and performance are concerned. Making this determination requires intimate knowledge of the scenarios in which the device will operate — and that is just the start. In order to set things up, you need to somehow model the system, which could be done in a ... » read more

The Zen Of Processor Design
By Ed Sperling - 15 Sep, 2016 - Comments: 0

Mark Papermaster, chief technology officer at Advanced Micro Devices, sat down with Semiconductor Engineering to discuss how to keep improving performance per watt, new packaging options, and the increasing focus on customization for specific tasks. What follows are excerpts of that conversation. SE: As we get more into the IoT and we have to deal with more data, not to mention cars where da... » read more

Controlling Heat
By Ann Mutschler - 12 Sep, 2016 - Comments: 0

Modeling on-chip thermal characteristics and chip-package interactions is becoming much more critical for advanced designs, but how to get there isn't always clear. Every chip, based on its target application, has a thermal design power (TDP) target. This is the typical power it can consume without overreaching the acceptable thermal limits in its intended environment. But in order to rate t... » read more

Focus Shifts To Architectures
By Ed Sperling - 08 Sep, 2016 - Comments: 1

Chipmakers increasingly are relying on architectural and micro-architectural changes as the best hope for improving power and performance across a spectrum of markets, process nodes and price points. While discussion about the death of [getkc id="74" comment="Moore's Law"] predates the 1-micron process node, there is no question that it is getting harder for even the largest chipmakers to st... » read more

Noise Killed My Chip
By Brian Bailey - 08 Sep, 2016 - Comments: 0

In the past, noise was considered an annoyance, especially for analog circuitry. But today chips are actually failing because insufficient analysis was performed. Noise types that used to be second-order effects are becoming primary factors that have to be considered. This is happening at the same time that noise margins are getting smaller, both in the amplitude and temporal dimensions. It ... » read more
