Power-Hungry Safety And Security
By Brian Bailey - 09 Apr, 2020 - Comments: 0

There is a price to pay for everything. When it comes to adding safety and security into a device, the costs in terms of power and area can be significant, but if the task is taken seriously, those costs can be managed and minimized. New analysis and implementation tools are coming to market that can also help to keep the costs contained. But it also requires the right mindset. As more indus... » read more

LPDDR4/4X DRAM Variants and Possible System Configurations
By Synopsys - 26 Feb, 2020 - Comments: 0

LPDDR is the de-facto standard for main-memory targeting mobile applications such as smartphones and tablets. Low-Power Double Data Rate Synchronous Dynamic Random Access Memories (LPDDR SDRAMs) or DRAMS offer high-performance while consuming significantly lower power than standard DDR memories, such as DDR5/4/3, which are ideal for systems requiring large memory capacity. For this reason, LPDD... » read more

Speeding Up 3D Design
By Brian Bailey - 14 Nov, 2019 - Comments: 0

2.5D and 3D designs have garnered a lot of attention recently, but when should these solutions be considered and what are the dangers associated with them? Each new packaging option trades off one set of constraints and problems for a different set, and in some cases the gains may not be worth it. For other applications, they have no choice. The tooling in place today makes it possible to de... » read more

High-Performance DSP And Control Processing For Complex 5G Requirements
By Graham Wilson - 12 Sep, 2019 - Comments: 0

In the early 2000s, digital signal processors (DSP) were simple in architecture and limited in performance, but complex in programming. However, they evolved to meet of the increased performance requirements of 3G cellular baseband modem applications. A typical 3G modem system would have a single DSP optimized for dual/quad SIMD MAC performance with basic DSP filter instructions like Fast Fouri... » read more

Why Integrated SIM Will Unleash The Secure, Mobile IoT
By Dana Neustadter - 01 Aug, 2019 - Comments: 0

Connected IoT devices such as sensors, object trackers, security cameras, intelligent traffic lights, wearables and smart meters are proliferating at a rapid pace. A significant number of connected IoT devices use cellular technology for communication. 5G is setting the stage for the next wave of devices to enable rapid IoT connectivity at an even greater scale. NB-IoT and LTE-M, which are low ... » read more

Adapting Mobile To A Post-Moore’s Law Era
By Ann Mutschler - 14 Feb, 2019 - Comments: 0

The slowdown in Moore's Law is having a big impact on chips designed for the mobile market, where battery-powered devices need to still improve performance with lower power. This hasn't slowed down performance or power improvements, but it has forced chipmakers and systems companies to approach designs differently. And while feature shrinks will continue for the foreseeable future, they are ... » read more

Power/Performance Bits: Nov. 20
By Jesse Allen - 20 Nov, 2018 - Comments: 0

In-memory compute accelerator Engineers at Princeton University built a programmable chip that features an in-memory computing accelerator. Targeted at deep learning inferencing, the chip aims to reduce the bottleneck between memory and compute in traditional architectures. The team's key to performing compute in memory was using capacitors rather than transistors. The capacitors were paire... » read more

What’s The Outlook for Memory?
By Mark LaPedus - 15 Nov, 2018 - Comments: 2

What a difference a year makes in the memory business. At this time last year, the industry was in the midst of a boom cycle for both NAND and DRAM. More specifically, there was huge demand for 3D NAND. Then, starting in the first quarter of 2018, the NAND market began to decline and it continues to fall. And now, the DRAM market is also falling off the cliff. So, it’s time to take a q... » read more

Reducing Time To Market For Security Solutions
By Udi Maor - 01 Nov, 2018 - Comments: 0

Security is now a common feature on most mobile devices, from fingerprint scanners to face ID. However, despite its widespread adoption, the time-to-market for developing security solutions still remains a challenge for OEMs, silicon providers (SiPs) and developers. Some of the most notable obstacles include: the availability of fully integrated security solutions incorporating existing IP, arc... » read more

Verification Trends Enabling A 5G Future
By Frank Schirrmeister - 23 Aug, 2018 - Comments: 0

Applications have driven requirements for verification for quite some time now, as I have written previously regarding Aero & Defense, AI and Machine Learning and the Internet of Things. In wireless communication, we are just at the brink of the transition to Fifth Generation Networks, or 5G. This transition will not only lead to new applications and use models that will impact our day-to-d... » read more
