Huawei Kirin 990 & Samsung Exynos 980 are the First Mobile SoCs with Integrated 5G Modem

[Update: post edited on September 6, 2019 with more details about Kirin 990 5G following the official launch of the processor] We’ve already seen mobile phones and laptops with the latest 5G cellular connectivity such as Samsung Galaxy S10 5G or Lenovo Project Limitless 5G laptop, which internally are designed with an Arm SoC plus a separate 5G modem chip. But as IFA 2019 is about to start, both Huawei and Samsung claim to have introduced the world’s first SoC with an integrated 5G modem with respectively Huawei Kirin 990 and Samsung Exynos 980. We should note that MediaTek is working on their own 5G SoC as well. Samsung Exynos 980 Samsung has already made the announcement so we have Exynos 980 key features and specifications: CPU – Octa-core processor with two Arm Cortex-A77 cores @ 2.2GHz, six Arm Cortex-A55 cores @ 1.8GHz GPU – Mali-G76 MP5 GPU Integrated NPU […]

CDVA (Compact Descriptors for Video Analysis) Enable “Video Understanding”

One of the most popular applications of artificial intelligence is object detection where you have models capable of detecting objects or subjects being cats, dogs, cars, laptops, or other. As I discovered in a press release by Gyrfalcon, there’s something similar for videos called CDVA (Compact Descriptors for Video Analysis) that’s capable of analyzing the scene taking place, and describe it in a precise manner. The CDVA standard, aka MPEG ISO/IEC 15938-15, describes how video features can be extracted and stored as compact metadata for efficient matching and scalable search. Gyrfalcon published a press release, their Lightspeeur line of AI chips will adapt CDVA. You can get the technical details in that paper entitled “Compact Descriptors for Video Analysis: the Emerging MPEG Standard”. CDVA still relies on (CNN Convoluted Neural Network) but do so but extracting frames first, append a timestamp and the encoded CDVA descriptor to the video, which […]

ULX3S Education Board is Powered by Lattice Semi ECP5 FPGA & ESP32 WiFi/BLE Module

ULX3S Lattice ECP5 FPGA Educational Board

A few days ago, we covered the KiCAD designed OrangeCrab open-source hardware board powered by a Lattice Semi ECP5 FPGA, and compliant with Adafruit Feather form factor. It’s turned out there’s another Lattice Semi ECP5 FPGA board that’s also designed with KiCAD and open source hardware. Radiona ULX3S differs are it’s larger and exposes more I/Os since it was specifically designed to meet the meets of the digital logic course at the Faculty of Electrical Engineering and Computing (FER) of the University of Zagreb in Croatia. ULX3S specifications: FPGA – Lattice ECP5 LFE5U-85F-6BG381C with 84K LUT System Memory – 32MB SDRAM @ 166 MHz Storage – 4–16MB Quad-SPI Flash for FPGA config and user data storage; MicroSD slot Audio – 3.5 mm jack with 4 contacts (analog stereo + digital audio or composite video) Video – Digital video (GPDI General-Purpose Diferential Interface) with 3.3V-5V I2C bidirectional level shifter Display – […]

$5 Longan Nano GD32V RISC-V Development Board Comes with LCD Display and Enclosure

There’s been some exciting news about RISC-V microcontrollers recently with Gigadevice announcing GD32V, one of the first RISC-V general-purpose microcontrollers, which outperforms its Arm Cortex-M3 equivalent in terms of performance and power consumption. The company also announced some development boards, but they are not quite that easy to purchase being listed on Tmall website in China. The good news is that Sipeed has introduced Longan Nano development board powered by GD32VF103CBT6 microcontroller, and it’s up for sale on Seeed Studio for $4.9. Longan Nano board specifications: MCU – Gigadevice GD32VF103CBT6 32-bit RISC-V (rv32imac) microcontroller @ 108 MHz with 128KB Flash, 32KB SRAM Storage – MicroSD card slot Display – 0.96″ 160×80 IPS RGB LCD connected via SPI USB – 1x USB Type-C port for power and programming Expansion – 2x 16 through holes (2.54mm pitch) exposing 3x USART, 2x I2C, 3x SPI, 2x I2S, 2x CAN, 1x USBFS (OTG), 2x […]

AndesCore N22 RISC-V Core Supports RV32IMAC or RV32EMAC Instruction Sets

We covered Gigadevice GD32V general-purpose microcontroller with a RISC-V “Bumblebee” core last week, and I was informed that Andes Technology had recently introduced AndesCore N22 RISC-V “Bumblebee” IP core capable of supporting either RV32IMAC or RV32EMAC instruction sets. A web search did not reveal any specific information about what “Bumblebee” RISC-V cores are exactly, or maybe it’s in reference that many can be coupled in parallel. But that’s just a small detail, let’s check out in some details what AndesCore N22 core has to offer. The RISC-V core is designed for entry-level MCUs found in IoT devices and wearables, and is capable of deeply embedded protocol processing for I/O control, storage, networking, AI and AR/VR. Highlights of AndesCore N22: AndeStar V5 (RV32IMAC) / V5e (RV32EMAC) Instruction Set Architecture (ISA), compliant to RISC-V technology plus Andes extensions architectured for performance and functionality enhancements 32-bit, 2-stage pipeline CPU architecture 16/32-bit mixable instruction […]

Nordic Thingy:91 Cellular IoT Prototyping Platform Comes with 16 Sensors

Nordic Semiconductor launched the Nordic Thingy:52 back in mid-2017 in the hopes of bringing app and web developers into the hardware ecosystem as fast and easy as possible. The Nordic Thingy:52 was a Bluetooth 5 IoT sensor development kit based on the company’s nRF52832 WiSoC. Although the Nordic Thingy:52 kit is still very much available for purchase and support always available, Nordic Semiconductor has gone further launching a new development kit called the Nordic Thingy:91 targeting cellular IoT applications. The Nordic Thingy:91 is a cellular IoT prototyping platform with support for LTE-M, NB-IoT plus GPS option. Even though IoT connectivity standards like LoRaWAN, BLE, WiFi, ZigBee, and others are very much growing and expanding, Nordic Semi is fully backing cellular technology, something that has very much been available and most likely will still keep been available, and the adoption of 5G is another testimony to that. Cellular is here, and […]

Fairphone 3 Socially Responsible Android Smartphone Launched for 450 Euros

Most phones today are disposable items, and if yours stops working for whatever reason it’s hard to repair it yourself work, and repairing it at the shop may prove to be too expensive. They are not really expandable either, so if you want a new feature, you may have to buy a completely new phone instead of simply adding a module with the functionality. The difficulty in repairing the phone and the lack of modularity leading to electronics waste. Finally, consumer products are cost-optimized, and that’s great for your wallet, but it may come at the cost of being made by slave labor either directly at the factory, or indirectly through the mining of materials. Aren’t you already feeling bad being complicit in destroying the planet and sponsoring human suffering while reading this on your device? Good! But luckily there’s a solution with Fairphone that aims to be an ethical […]

MPEG Video Coding for Machines (VCM) is in the Works

A video codec for machines seems like a good topic for the first of April, or an article on the Onion. But based on a recent press release by Gyrfalcon Technology, this may become a real thing as the company partnered with China Telecom, and proposed a new video codec called “Video Coding for machines” (VCM) that provides compression coding for machine vision and human-machine hybrid vision. Apparently a recent study published by Cisco in 2018, humans will become bit players in the “video watching business”, and Machine-to-Machine (M2M) applications will represent the greatest usage of Internet video traffic over the next four years. So the goal of the VCM group will be to establish a new standard that will improve the previous generation video coding and decoding standards such as H.264 (AVC), H.265 (HEVC) and H.266 (VVC). Few details are provided so far, and I can’t find any VCM […]
