Intel and Micron Promise 1000x Faster Storage with 3D XPoint Memory

Non-volatile memory is usually the bottleneck in electronics systems and computers, as it takes much longer to move data from storage than in RAM or cache, so any improvement may yield great benefits, especially when your application requires lots of I/Os. Micron and Intel claim to have developed a new category of memory, and announced 3D XPoint (Read “3D cross-point”) memory as the first break through since the launch of NAND Flash in 1989. There’s great variability between different NAND flash chips, but the companies announced that 3D XPoint is 1,000 times faster and endurant (write cycles) than NAND flash, and 10 times denser than conventional DRAM. The technology would mainly benefit most applications, but especially more demanding ones such as high resolution gaming (4K/8K), real-time pattern recognition, and genomics. Based on the presentation video below, it even seems 3D XPoint memory can be used to replace RAM and NAND […]

Nvidia SHIELD TV Benchmarks in Ubuntu Shows Core i3 Like Performance

Nvidia SHIELD Android TV was announced this March with Nvidia Tegra X1 octa-core Cortex A57 + A53 processor. So far, I had not seen any Ubuntu or other Linux distribution port, but Michael Mirabel of Phoronix got remote access to a Shield TV PRO – model with a 500GB hard drive – running Ubuntu 14.10. It’s not clear who provided access, either Nvidia or third parties, but somebody posted an Ubuntu 14.10 port on XDA Developers Forums recently so it might be that one. He obviously ran Phoronix Test Suite on the device, and compared to it some other ARM devices (Compule Utilite, Jetson TK1), MIPS Creator CI20, low power x86 devices (Compute Stick, Intel NUC with Celeron N2820), and an Intel Core i3-5010u NUC. The Tegra X1 platform easily beats all other low power platforms, and comes close to the Core i3 mini PC in most tests. In the […]

$55 UWatch UX Strapless Heart Rate Monitor Watch Syncs with iOS and Android Devices

Last time I checked about heart rate monitor, they required a chest strap to monitor ones heart rate, which I found cumbersome. It’s been while though, and I’ve now been informed that a low cost Bluetooth strapless heart rate monitor watch was available for $59.99 on GeekBuying. This type of product should provide a much more accurate evaluation of your daily calories burn rate than typical fitness bands based on an accelerometer and gyro sensor, but I’m not quite sure how they compare to the old models with a chest strap. Uwatch UX specifications and features: SoC – Mediatek Aster MT2501 ARM7 processor @ 108 MHz (A lower end version of MT2502 used in LinkIt One Devkit) System Memory – 32MB RAM Storage – 24MB NOR flash Heart rate monitor – Built-in photoelectric heart rate sensor Other sensors – magnetometer, 3-axis gravity and acceleration sensor Connectivity – Bluetooth 4.0 and […]

New FCC Rules May Prevent Installing OpenWRT on WiFi Routers

Many cheap WiFi routers are sold with the vendor firmware, but the most popular ones likely also support OpenWRT, which some users may prefer as it is much more customizable. However, this may soon become more difficult according to a talk at the upcoming “Wireless Battle of the Mesh” which will take place on August 3-8 in Maribor, Slovenia. The talk scheduled for August 6 at 15:00 is entitled “openWRT vs. FCC – forced firmware lockdown?” and Simon Wunderlich, the speaker, provided the following abstract: The new FCC rules are in effect in the United States from June 2nd 2015 for WiFi devices such as Access Points. They require to have the firmware locked down so End-Users can’t operate with non-compliant parameters (channels/frequencies, transmit power, DFS, …). In response, WiFi access point vendors start to lock down firmwares to prevent custom firmwares (such as OpenWRT) to be installed, using code […]

PiPo X1 is a Windows 10 Bay Trail HDMI TV Stick

PiPo used to the mostly know for its low cost tablets, but then they started launching ARM based mini PCs, and followed with x86 mini PCs such as the popular PiPo X7. Netbook Italia found out the company is now working on a new HDMI TV stick that will run Windows 10, but they must have run out of “lucky” names because the product will apparently be called PiPo X1, a name they already used for a Rockchip RK3188 TV stick… The hardware is not really interesting, as it has basically the same specs as the other Bay Trail-T sticks on the market: SoC – Intel Atom Z3735F “Bay Trail” quad core processor @ 1.33 GHz (Bust frequency: 1.83 GHz) with Intel HD graphics Gen 7 System Memory – 2 GB Storage – 32 GB eMMC + micro SD slot up Video & Audio Output – HDMI Connectivity – 802.11 […]

ODROID-C1+ Board is an Upcoming Upgrade to ODROID-C1 Board

ODROID-C1 board has been relatively popular thanks to its great hardware features and good software support for its $35 price tag. In mid-June however, ODROID-C1 got out of stock due to sudden large orders, and it was only scheduled to sale again in early August because of long leadtime for some components. It turns out ODROID-C1 may never sell again, simply because it will be replaced by ODROID-C1+ with various improvements. It’s still very much based on ODROID-C1 with Amlogic S805 processor, 1GB RAM, and an eMMC sockets, but Hardkernel made the following improvements: HDMI connector change to Type-A from Type-D (micro HDMI). Improved SD card compatibility CEC function whether the RTC backup battery is installed or not ODROID-C1+ can be powered from the USB OTG port as well as DC-Jack I2S signals exposed for external audio DAC All of which are welcomed modifications. The board size will remain the […]
