UFS 3.1 Storage Devices to Deliver Better Performance, Lower Power Consumption

JEDEC first introduced UFS 3.0 embedded flash in September 2017 with promises of 2.4GB/s transfer rates, and somehow this was bumped to 2.9GB/s (23.2 Gbps) when UFS 3.0 specification was published in January 2018. JEDEC has now published UFS 3.1 specification with the same theoretical performance, but some new features that should improve write performance, random read performance, as well as lower power consumption and costs. Precisely two documents are now available for purchase, unless you work for a JEDEC member, in which case those are free downloads: The Universal Flash Storage (UFS) version 3.1, JESD220E. An optional new companion standard, JESD220-3: UFS Host Performance Booster (HPB) Extension. The first defines three main improvements as part of UFS 3.1: Write Booster – an SLC non-volatile cache that amplifies write speed DeepSleep – a new UFS device low power state targeting lower-cost systems that share UFS voltage regulators with other functions […]

Mediatek Helio P60 Cortex A73/A53 Mobile Processor Includes NeuroPilot AI technology

Neural Network Accelerators (NNA) may have become a must-have block in high-end mobile processors. Huawei Kirin 970, Samsung Exynos 9810, and Qualcomm Snapdragon 845 (via its Hexagon DSP) processors all come with NNA or NPU (Neural Processing Unit) to speed up tasks and comsume less power for tasks related to artificial intelligence / machine learning. Mediatek has also jumped on the bandwagon with Helio P60 chipset featuring four Cortex A73 cores, four Cortex A53 cores, an Arm Mali-G72MP3 GPU and a multi-core mobile APU (AI Processing Unit) leveraging the company’s NeuroPilot AI technology. Mediatek P60 key specifications: CPU – big.LITTLE Octa-core with four Arm Cortex-A73 up 2.0 GHz and four Arm Cortex-A53 up to 2.0 GHz GPU – Arm Mali-G72 MP3 at 800MHz Multi-core AI processing unit (Mobile APU) – 280 GMAC/s; offers deep learning facial recognition, object and scene identification, user behavior-informed performance and other AI and AR application […]

HiKey 960 Android Development Board Gets a 4GB RAM Version for $250

Hikey 960 development board is one of the most powerful Arm boards on the market thanks to Huawei/Hisilicon Kirin 960 octa-core processor with four ARM Cortex A73 cores, four Cortex A53 cores, and a Mali-G71 MP8 GPU, fast storage with 32GB UFS 2.1 flash, and 3GB LPDDR3 memory. Like the earlier Hikey (620) board, the board is also an official reference board for AOSP, so you should be able to run the latest Android version, and also play with sensors using Neonkey SensorHub 96Boards mezzanine board. If you are somehow limited by the 3GB RAM on the board, you can rejoice as Seeed Studio has just launched a 4GB RAM version selling for $249, or about $10 extra. Note that shipping is only scheduled for February 2, 2018, so those are pre-orders. The rest of the specifications for Hikey 960 4GB RAM version are unchanged: SoC – Huawei Kirin 960 […]

UFS 3.0 Embedded Flash to Support Full-Duplex 2.4GB/s Transfer Speeds

All my devices still rely on eMMC flash for storage, but premium smartphones, for example, make use of UFS 2.0/UFS 2.1 flash storage with performance similar to SSD, with Samsung UFS 2.0 storage achieving up to 850MB/s read speed, 260 MB/s write speed, and 50K/30K R/W IOPS. UFS 3.0 promises to roughly double the performance of UFS 2.0/2.1 with transfer rates of up to 2.4 GB/s, and separately, the UFS Card v2.0 standard should deliver UFS 2.1 performance on removable storage. Several Chinese and Taiwanese websites, including CTimes and Benchlife, have reported that companies have started getting UFS 3.0 & UFS Card v2.0 licenses from JEDEC, and Phison is working on a controller to support both new standards, and scheduled to launch in 2018. Premium smartphone SoC are only expect to support UFS 3.0 in 2019 and beyond, and hopefully by that time eMMC will have been replaced by UFS 2.0/2.1 […]

Embedded Linux Conference & Open Source Summit Europe 2017 Schedule

The Embedded Linux Conference & IoT summit 2017 took place in the US earlier this year in February, but there will soon be a similar event with the Embedded Linux Conference *& Open Source Summit Europe 2017 to take up in Europe on October 23 – 25 in Prague, Czech Republic, and the Linux Foundation has just published the schedule. It’s always useful to find out what is being discussed during such events, even if you are not going to attend, so I went through the different sessions, and compose my own virtual schedule with some of the ones I find the most interesting. Monday, October 23 11:15 – 11:55 – An Introduction to SPI-NOR Subsystem – Vignesh Raghavendra, Texas Instruments India Modern day embedded systems have dedicated SPI controllers to support NOR flashes. They have many hardware level features to increase the ease and efficiency of accessing SPI NOR […]
