Security Risks Grow With 5G


5G mobile phones can download a movie in seconds rather than minutes, but whether that can be done securely remains to be seen. What is clear from technology providers, though, is they are taking security very seriously with this new wireless technology. More data is in motion, and the value of that data is growing as users rely on mobile devices for everything from banking to automotive saf... » read more

More NoC Wisdom


A common experience for anyone promoting a disruptive technology is that prospective customers understand that what is being offered is different. Still, without a familiar reference to compare, they extrapolate expectations unreliably. Sometimes expectations are extrapolated to infinity: “My existing solution has limitations, but the new technology should have no limitations.” Sometimes ex... » read more

Implementing An AES Cipher On Application-Specific Processors


In the previous blog post, “Embedded Security Using Cryptography”, we looked at how cryptography can be used for securing assets in embedded systems and ensure confidentiality, integrity and authenticity, or in short “CIA”. In this blog, we will explore the Advanced Encryption Standard (AES) and how to implement an AES engine on Cadence Tensilica Xtensa application-specific processors. ... » read more

Navigating The Seas Of FIPS 140-2 CMVP With Certified Root Of Trust And TRNG IP


No captain worth his salt would set sail without an experienced navigator at his side. Likewise, when navigating the FIPS 140-2 CMVP process, it’s extremely valuable to have a partner that has already successfully made the journey. More specifically, working with a partner that offers CMVP-certified IP can streamline the process and increase the success of achieving CMVP certification of chip... » read more

Nanoporous Dielectric Resistive Memories Using Sequential Infiltration Synthesis


Abstract "Resistance switching in metal–insulator–metal structures has been extensively studied in recent years for use as synaptic elements for neuromorphic computing and as nonvolatile memory elements. However, high switching power requirements, device variabilities, and considerable trade-offs between low operating voltages, high on/off ratios, and low leakage have limited their utility... » read more

Improved Performance of GaN-Based Ultraviolet LEDs with the Stair-like Si-Doping n-GaN Structure


Abstract "A method to improve the performance of ultraviolet light-emitting diodes (UV-LEDs) with stair-like Si-doping GaN layer is investigated. The high-resolution X-ray diffraction shows that the UV-LED with stair-like Si-doping GaN layer possesses better quality and a lower dislocation density. In addition, the experimental results demonstrate that light output power and wall plug effici... » read more

STMicroelectronics Methodology And Process For Heterogeneous Automotive Package Design


As a leading supplier of automotive semiconductors, STMicroelectronics must continue to move fast to develop and deliver leading-edge solutions. Employing package design as part of system innovation requires the STMicroelectronics Back-End Manufacturing Technology R&D organization to embrace the key driving forces of product development. In the automotive field, package designers need to... » read more

Using Machine Learning For Characterizations Of NoC Components


Modern NoC (Network-on-Chip) is built of complex functional blocks, such as packet switches and protocol converters. PPA (performance/power/area) estimates for these components are highly desirable during early design phases – long before NoC gate level netlist is synthesized. At this stage a NoC component is a soft module, described by a set of architectural parameters, like the bit width of... » read more

HBM3 Memory: Break Through To Greater Bandwidth


AI/ML’s demands for greater bandwidth are insatiable driving rapid improvements in every aspect of computing hardware and software. HBM memory is the ideal solution for the high bandwidth requirements of AI/ML training, but it entails additional design considerations given its 2.5D architecture. Now we’re on the verge of a new generation of HBM that will raise memory and capacity to new hei... » read more

Building A Secured Internet Of Things


The emerging Internet of Things (IoT) presents tremendous opportunities for innovative companies to deliver products and services to make industry more efficient, transportation safer and the everyday lives of people more convenient and fulfilling. But with great good there also can be great risk. Remote, intelligent monitoring and control for factories, homes, cities, and cars can increase eff... » read more
