At last the right decision on our 5G network has been taken – to go for an O-RAN network. “The objective we’re working towards is getting the standards established to allow us to have an an Open-RAN network which allows opportunities for UK suppliers,” said the DCMS Secretary of State Oliver Snowden in the Commons […]
Palma Ceia SemiDesign is sampling its new 802.11ax transceiver chip in a 1×1 MIMO configuration
By Gina Roos, editor-in-chief
Fabless semiconductor company Palma Ceia SemiDesign has announced sampling of its new PCS11ax28 transceiver chip for the 802.11ax Wi-Fi standard, also known as Wi-Fi 6. The company is currently working with global partners to expand supply.
The 802.11ax standard is the newest version of the 802.11 standard for wireless network transmissions. The new standard offers greater maximum data rates and a higher network capacity to support more IoT devices. In addition, Wi-Fi 6 is backward-compatible with the previous version of the Wi-Fi standard, 802.11ac.
Based on high-performance 28-nm HPC technology, the Wi-Fi chip offers low power consumption, with peak RX power consumption of 195 mW for the 1×1 MIMO configuration. It supports Wi-Fi 6 channel bandwidths of 20 MHz, 40 MHz, and 80 MHz, and all Wi-Fi 6 modulations up to 1024-QAM. The analog I/O can enable Bluetooth over the 2.4-GHz channel. Availability of 2×2 and 4×4 configurations is expected in Q3 2020.
Sample requests can be made via the Palma Ceia SemiDesign website or by email [email protected]
UK telcos have been banned from buying Huawei 5G switchgear as from December 31st 2020. All Huawei 5G kit in the network must be taken out by 2027. These measure were announced by the DCMS Secretary of State Oliver Dowden in the Commons earlier today An hour or so before the announcement the Chairman of […]
TI’s zero-drift Hall-effect current sensors enable accurate measurements over time and temperature in high-voltage systems
By Gina Roos, editor-in-chief
Texas Instruments (TI) has claimed the industry’s first zero-drift Hall-effect current sensors that enable the lowest drift and highest accuracy over time and temperature. The TMCS1100 and TMCS1101 also provide 3-kVrms isolation, which is an important specification for AC or DC high-voltage systems such as industrial motor drives, solar inverters, energy-storage equipment, and power supplies.
Demand for precise current measurement and high reliability in industrial systems often comes at the price of increased board space or design complexity, said TI. However, with these new devices, the solution size remains compact without increasing design time, and provides consistent performance and diagnostics over a longer device lifetime.
This is thanks in part to the zero-drift architecture and real-time sensitivity compensation of the TMCS1100 and TMCS1101, which enables the high performance even under temperature changes and equipment aging. The devices provide total sensitivity drift over temperature of 0.45%, maximum, which is at least 200% lower than other magnetic current sensors, said TI, and a maximum full-scale offset drift of
SANTA CLARA, Calif., July 14, 2020 (GLOBE NEWSWIRE) — AMD (NASDAQ: AMD) and Google Cloud today announced the beta availability of Confidential Virtual Machines (VMs) for Google Compute Engine powered by 2nd Gen AMD EPYC™ processors, taking advantage of the processors’ advanced security features.The first product in the Google Cloud Confidential Computing portfolio, Confidential VMs, enables customers for the first time to encrypt data in-use while it is being processed and not just when at rest and in-transit. Based on the N2D family of VMs for Google Compute Engine, Confidential VMs provide customers high performance processing for the most demanding computational tasks and enable encryption for even the most sensitive data in the cloud while it is being processed.“At Google Cloud, we believe the future of cloud computing will increasingly shift to private, encrypted services where users can be confident that the confidentiality of their data is always under their control. To help customers in making that transition, we’ve created Confidential VMs, the first product in our Google Cloud Confidential Computing portfolio,” said Vint Cerf, vice president and chief internet evangelist, Google. “By using advanced security technology in the AMD EPYC processors, we’ve created a breakthrough technology that allows customers to encrypt their data in the cloud while it’s being processed and unlock computing scenarios that had previously not been possible.”“As enterprises migrate tasks to the cloud for reasons including ease of management, scalability, and reduced costs, they often stop short of moving more sensitive workloads due to security concerns,” said Dan McNamara, senior vice president and general manager, Server Business Unit, AMD. “To help provide the confidence that customers can move their sensitive workloads to the cloud, AMD and Google worked together on the Google Confidential VMs to take advantage of an advanced security feature, Secure Encrypted Virtualization, within AMD EPYC processors. This helps enable a unified and consistent level of hardware-based security for applications and workloads in the cloud. As well, AMD and Google have worked together to help customers both secure their data and achieve high performance of their workloads.”The Confidential VMs from Google provide:Real time encryption-in-use – Google Cloud customers can encrypt data-in-use, taking advantage of advanced security features offered by the 2nd Gen AMD EPYC processor together with Confidential Computing cloud services, bringing a breakthrough in the level of cloud data protection,Secure Encrypted Virtualization (SEV) – an advanced security feature available on AMD EPYC processors, which encrypts VM memory using a dedicated per-VM key that is generated and managed by the embedded security processor,“Lift and Shift Confidentiality” – AMD and Google have simplified the use of Confidential Computing, making the transition to Confidential VMs seamless as customers do not need to make any code changes to their applications to benefit from these VMs,High-performance VMs – Confidential VMs offer similar performance to Google N2D VMs, which are powered by high-performance 2nd Gen AMD EPYC processors.Driving Innovation with AMD and GoogleConfidential Computing can unlock computing scenarios previously not possible, including:Multi-party Computation – Situations in which organizations want to collaborate with each other on private datasets, while protecting the confidentiality of the data.Data Access and Confidentiality – Confidential VMs can limit the exposure of the data and who can access it by encrypting the data even when it is being processed.Organizations will be able to share confidential data sets and collaborate on research in the cloud across geographies and competitors confidently due to the high-performance capabilities and advanced security features of the AMD EPYC processors coupled with the innovative Confidential Computing technology offered by Google.AMD EPYC Processors, Powering the Modern Security Focused CloudAMD EPYC processors power more than 120 VM types from cloud providers and hosts around the world that support a variety of workloads including high-performance, general purpose, memory bound and more.As well, AMD is committed to supporting the advancement for security across cloud computing as it recently joined the Confidential Computing Consortium.Confidential VMs are available to all GCP customers in the following GCP regions – asia-southeast1, europe-west1, europe-west4, us-central1 and are available for Google Compute Engine in Beta.Supporting ResourcesRead more about Confidential VMs at the Google Cloud blog hereLearn more about AMD EPYC processors hereLearn more about AMD EPYC for the cloud hereFor workload solutions by AMD for the confidential VMs, visit hereFollow AMD on TwitterAbout AMDFor more than 50 years AMD has driven innovation in high-performance computing, graphics and visualization technologies ― the building blocks for gaming, immersive platforms and the datacenter.
