Marvell Announces AP806 Cortex A72 & ARMADA A3700 Cortex A53 Virtual SoCs based on MoChi & FLC Architecture

Marvell has published a press release introducing AP806 quad core Cortex A72 and ARMADA A3700 dual and single core Cortex-A53 chips. But these two chips are called Virtual SoCs (VSoC) and they are said to use MoChi and FLC (Final Level-Cache) architecture. What does this all means? If I understand correctly, Marvell has decided to create modular SoCs that may just integrate the minimum: CPU, GPU, and memory controller, with other peripherals like Ethernet, SATA, LTE Modem added to the virtual SoC in some ways just like legos. This is done in order to mitigate the cost of manufacturing chips with advanced process nodes (e.g. Finfet 16) with usually has high steep mask costs, and wafer prices. So they may have a single AP806 MoChi module, to create multiple SoCs using different MoChi modules to add peripherals. Marvell listed some of the key befinits of modular SoCs: Changing existing software […]

Zidoo X6 Pro Android TV Box Review

Zidoo X6 Pro is a 64-bit ARM Android TV Boxes based on Rockchip RK3368 processor, promising support for HDMI 2.0 and video decoding up to 4K2K @ 60Hz. While the others I’ve tried so far, such as Beelink i68, are pre-loaded with some version of Kodi 14.2, X6 Pro comes with a modified version of Kodi 15.1. I published pictures of the Zidoo X6 Pro TV box and board a few days ago, and today I’ll review the box’ features, performance, and capabilities. First Boot, Settings and First Impressions I’ve connected a USB hard drive to one of the two USB ports, as well as a USB hub with two RF dongles for Tronsmart Mars G01 gamepad and MeLE F10 Deluxe air mouse, a USB keyboard, and a USB webcam. I’ve also inserted an Ethernet cable, an HDMI cable, an optical audio cable, a Class 10 micro SD card, as […]

Walabot MIMO Radar Board Can See Through Walls Thanks to Vayyar 3D Imaging Sensors

A few days ago, I wrote about Orbbec Astra 3D camera that can analyze distance and depth to form a 3D image of object. However, this solution uses an IR sensors, and while it can fulfill the needs of many application it does not allow to see through object, and that’s exactly what Walabot wideband MIMO radar board promises to do thanks to Vayyar 3D imaging sensor and a dozen of RF antennas. Some of the key features and preliminary specifications of Walabot board include: Vayyar VYYR2401 3D imaging sensor 12 (or is it 14?) non-contact antennas array system based on “Octopus A3 System on chip” Build in Tx/Rx linear polarized wide-band antennas from 3-10Ghz. On-board Cypress FX3 controller for communication and pre-processing EEPROM (for inventory and calibration information) Walabot interface connectors: Micro-USB 2.0 for high-rate data communication. Option to provide supply from USB. Single supply voltage 4.5-5.5v input for […]

FLIF Lossless Image Format Claims to Outperform PNG, JPEG2000, WebP, and BPG

FLIF, which stands for Free Lossless Image Format, is a new lossless image format that is said to provide better compression ration than PNG, lossless JPEG2000, lossless WebP, and lossless BPG for all king of images including medical images, geographical maps, cliparts and so on. Beside being lossless, FLIF is also progressive, so a lower quality version of the image can be displayed early while the download is still in progress. The developer has uploaded a video comparing how a PNG image and FLIF image would load in a slow network. Other FLIF features include: Lossless compression Greyscale, RGB, RGBA Up to 16 bits color depth per channel (high dynamic range) Interlaced (default) or non-interlaced Animation support “Encoding and decoding speeds are not blazingly fast, but they are in the right ballpark” Based on MANIAC (Meta-Adaptive Near-zero Integer Arithmetic Coding) algorithm developed by Jon Sneyers and Pieter Wuille. (However details […]

Archos Introduces Free PicoWAN IoT Gateway, Costing 75 Cents Per Year Per Connected Device

The Internet of Things is promising billions of connected devices in the next few years, and while devices at home can usually connect through your broadband connection at no extra cost, devices on the field may need to use cellular connectivity and cheap 2G network are being phased out by Telcos. Weightless, operating over white space frequencies, is one of several solutions proposed to connect IoT objects over longer distances, but Archos has their own project with PicoWAN pico-gateways using LoRa(WAN) protocol which allows for several kilometers range. PicoWAN would plug into your wall socket, connect to your broadband network over WiFI and offer connectivity to various “things” over LoRa. Creating a cellular network is expensive, due to the costs of base stations, but PicoWAN is so cheap, 100 times cheap than traditional base stations, that Archos plans to giveaway 200,000 gateways across Europe to create an IoT network. That […]

Xiaomi Mi Smart Remote Center Review

Xiaomi Mi Smart Remote Center is a tiny box with WiFi connectivity and IR transmitters that is used to control infrared enabled devices such as TVs, medai players, air conditioners and more with your Android smartphone. The good thing is that it only costs $20, so I asked GearBest to send a sample to check it out, which they did. I’ll start this review by checking out the hardware, before running MiHome app to control a television and air conditioner. Xiaomi Mi Smart Remote Center Unboxing and Teardown The package is just a cardboard box with Mi logo. Once you open the page there’s a sticker with the QR core redirecting to MiHome app. You can peel it off, and take the box out of the package, where you’ll also find a USB to micro USB cable for power, and a user’s manual in Chinese only. To open the device […]
