Always-On DSPs
By Ed Sperling - 28 Dec, 2021 - Comments: 0

There are tradeoffs between powering circuits down to save power and waking them up to respond to voice and visual commands. Prakash Madhvapathy, director of product marketing and product management at Cadence, talks about the best ways to deploy digital signal processors, why multiple DSPs are often better than just one, and what penalties there are for various approaches. » read more

Power/Performance Bits: Dec. 28

Shrinking LEDs Researchers from King Abdullah University of Science and Technology (KAUST) are working to make LEDs smaller. Micrometer-scale light-emitting diodes (μLEDs) could be an ideal building block for future microLED displays, but devices based on nitride-based alloys used to achieve a broad color range become poor emitters of light when shrunk to micrometer scales. “The main ... » read more

Batteries Take Center Stage
By Heidi Elliott - 27 Dec, 2021 - Comments: 0

For any mobile electronic device, the biggest limiting factors are the size, age, type, and utilization of the batteries. Battery technology is improving on multiple fronts. The batteries themselves are becoming more efficient. They are storing more energy per unit of area, and work is underway to provide faster charging and to increase the percentage of that energy that can be used, as well... » read more

Compact optical amplifier Researchers at Chalmers University of Technology propose a new optical amplifier design that is compact, high-performance, and doesn't generate excess noise. “We have developed the world's first optical amplifier that significantly enhances the range, sensitivity and performance of optical communication, that does not generate any excess noise – and is also com... » read more

Continuous Integration For Digital Design
By Christian Skubich - 17 Dec, 2021 - Comments: 0

By Christian Skubich and Nico Peter In 2001, the Manifesto for Agile Software Development [1] laid the foundation for many modern software development processes. Today, 20 years later, agile methods are in widespread use in numerous domains. Out of the participants in the study Status Quo (Scaled) Agile 2020 [2], only 9% still relied on classic project management methods. One core element... » read more

Power/Performance Bits: Dec. 14

Improved digital sensing Researchers from Imperial College London and Technical University of Munich propose a technique to improve the capability of many different types of sensors. The method addresses voltage limits in analog-to-digital converters and the saturation that results in poor quality when an incoming signal exceeds those limits. “Our new technique lets us capture a fuller ra... » read more

Revving Up SiC And GaN
By Ann Mutschler - 13 Dec, 2021 - Comments: 0

Silicon carbide (SiC) and gallium nitride (GaN) are becoming more popular for power electronics, particularly in automotive applications, driving down costs as volumes scale up and increasing the demand for better tools to design, verify, and test these wide-bandgap devices. Both SiC and GaN are proving essential in areas such as battery management in electric vehicles. They can handle much ... » read more

Week In Review: Design, Low Power
By Jesse Allen - 10 Dec, 2021 - Comments: 0

Intel intends to take Mobileye public in mid-2022 on a US market through an IPO of newly issued stock. The subsidiary, which Intel acquired in 2017, develops SoCs for ADAS and autonomous driving solutions. Mobileye has achieved record revenue year-over-year with 2021 gains expected to be more than 40 percent higher than 2020, highlighting the powerful benefits to both companies of our ongoing p... » read more

Amdahl Limits On AI
By Brian Bailey - 09 Dec, 2021 - Comments: 0

Software and hardware both place limits on how fast an application can run, but finding and eliminating the limitations is becoming more important in this age of multicore heterogeneous processing. The problem is certainly not new. Gene Amdahl (1922-2015) recognized the issue and published a paper about it in 1967. It provided the theoretical speedup for a defined task that could be expected... » read more

Can Coherent Optics Reduce Data-Center Power?
By Bryon Moyer - 09 Dec, 2021 - Comments: 0

As optical bandwidth requirements increase, system designers are turning to “coherent” modulation schemes that can place more data on the same laser light, and lower power over long connections. A newer question is whether those savings could be achieved for short connections within data centers, as well. “Coherent is the direction everything's moving, because for a given system and... » read more
