Intel Skylake-U Processors Run as Low as 7.5W TDP. A Closer Look at Configurable TDP

I try to mostly cover low power systems on this blog, so when it comes to x86 processors I have a cut off TDP of 10 Watts. The next generation of Intel Skylake processors have a TDP of 15 Watts, but when I read Skylake-U lineup post on FanlessTech, I discovered Intel processors also have a configurable TDP option, and in the case of Skylake-U processor their configurable TDP (cTDP) can be as low as 7.5W or 10W depending on models. U-Processor family has Pentium and Celeron processors, but also Core i3, Core i5 and even Core i7 processors such as i7-6600U and i7-6500U clocked up to 3.4 GHz and all with a 15W TDP, but you’ll also notice a column called “cTDP Down” showing 7.5W and 10W values, which shows the great progress made by Intel with regards to low power design. So I decided to look into configurable […]

Freescale i.MX6 DualPlus and QuadPlus SoCs Gets Faster 2D and 3D Graphics, Higher Memory Bandwidth

Freescale unveiled three new models for its i.MX 6 family processor for consumer, industrial and automotive markets in May. Two models are an upgrade to existing i.MX6 Quad and i.MX6 Dual processors, as the new i.MX 6QuadPlus and i.MX6DualPlus processors features four and two Cortex A9 cores, together with improved 2D and 3D GPUs delivering around 50% faster performance, an “optimized” SDRAM controller, more SRAM, and a prefetch and resolve engine. The third model, i.MX 6UltraLite, features a single ARM Cortex A7 core and hardware security, and targets applications such as electronic Point Of Sales (ePOS). That means there are now 9 i.MX6 processors, and today, I’ll focus on the two new “Plus” versions. Since they are based on the original i.MX6 Quad and i.MX6 Dual processors, the best way to have a look at these is to compare them to their predecessors. Features i.MX 6QuadPlus i.MX 6Quad i.MX 6DualPlus […]

ps_mem Shows Programs RAM Usage in Linux

There are several ways to see how much RAM is used in a Linux system with tools like free, vmstat, top, etc…, but today I’ve come across ps_mem which displays the RAM used for each program in a neat way. The post on lintut.com explains how to install it on Centos / Fedora:

yum install ps_mem -y

1	yum install ps_mem -y

As a Ubuntu user, I immediately tried apt-get install ps_mem, but there isn’t such package. After running apt-file search, I found it in w3af-console package:

sudo apt-get install w3af-console
sudo chmod +x /usr/share/w3af/core/controllers/profiling/ps_mem.py
sudo ln -s /usr/share/w3af/core/controllers/profiling/ps_mem.py /usr/sbin/ps_mem

sudo apt-get install w3af-console

sudo chmod +x /usr/share/w3af/core/controllers/profiling/ps_mem.py

sudo ln -s /usr/share/w3af/core/controllers/profiling/ps_mem.py /usr/sbin/ps_mem

Another way to install the script is to simply get it from Github. Running the command without options will list of programs with RAM usage from the smallest to the largest:

sudo ps_mem
 Private  +   Shared  =  RAM used	Program 

  4.0 KiB +  33.0 KiB =  37.0 KiB	inetutils-inetd

How to Install and Run Linux on Zidoo X1 TV Box

Now that I’ve completed Zidoo X1 review, I’ve decided to try out Ubuntu on the mini PC following a tip from one reader that Orange Pi 2 images can run on the platform since it’s based on the same Allwinner H3 processor, but with some limitations such as WiFi not working. There are three Linux firmware images for Orange Pi 2 on the download page: Lubuntu, Raspbian, and Debian server. I decided to go with Lubuntu image. First you need to download Lubuntu_1404_For_OrangePi2-mini2_v0_8_0_.img.xz image from Google Drive or Baidu, uncompress it, and then flash the image to a Class 10 micro SD card in Windows or Linux. I ran the following command line in a computer running Ubuntu 14.04:

sudo dd if=Lubuntu_1404_For_OrangePi2-mini2_v0_8_0_.img | pv | sudo dd of=/dev/sdX bs=16M

1	sudo dd if=Lubuntu_1404_For_OrangePi2-mini2_v0_8_0_.img \| pv \| sudo dd of=/dev/sdX bs=16M

Where X in sdX is the letter of your micro SD card, which you can find with lsblk. In some platforms, it might be /dev/mmcblkX instead of /dev/sdX. Once it’s […]

Cubieboard 5 (aka CubieTruck Plus) Development Board is Powered by Allwinner H8 SoC

Merrii unveiled H7 Hummingbird board based on Allwinner H8 octa core Cortex A7 processor a few days ago, but it turns out they’ve not been the only ones working on a board with that processor, as Cubietech also showcased prototypes of Cubieboard 5, which they also call CubieTruck Plus, around mid July. They’ve only shown pictures of the board, without much more information, but we can derive most specifications from the pictures: SoC – AllWinner H8 octa-core ARM Cortex-A7 processor @ up to 2.0GHz with PowerVR SGX544 GPU @ up to 700MHz System Memory – 2GB RAM (4x H5TQ4G63AFR-PCB DDR3 chips) Storage – FORESEE eMMC or NAND flash + micro SD card slot + SATA port (via GL830 USB 2.0 to SATA bridge) Video Output – HDMI and DisplayPort Audio – HDMI, optical S/PDIF, 3.5mm headphone jack, built-in microphone Connectivity – Gigabit Ethernet (RTL8211E), dual band WiFi 802.11 b/g/n and […]

HummingBoard Edge SBC Gets an mSATA/M.2 Connector, an eMMC Flash, and More I/Os

SolidRun launched its HummingBoard family last year with a board with a form factor similar to the Raspberry Pi, but instead of using a Broadcom processor, the boards were based on Freescale i.MX6 single, dual or quad core processors. The company has recently introduce a higher end board with Hummingboard Edge that adds an M.2 connector, eMMC flash, 7 to 36V DC power input, more camera interfaces, a DSI interface, and more GPIOs. The following comparison table shows the differences between the new Hummingboard Edge, and the older HummingBoard Pro and Base boards. HummingBoard-Edge HummingBoard-Pro HummingBoard-Base uSOM model i.MX6 based Solo to Quad Core uSOM Memory Up to 4GB DDR3 Storage uSD, eMMC, M.2/mSATA uSD, mSATA uSD Connectivity 1x RJ45*, 4x USB 2.0, mPCIE with SIM card holder 1x RJ-45*, 2x USB 2.0 Hosts, 2x USB 2.0 header, mPCIE half-size 1x RJ-45*, 2x USB 2.0 Hosts Media HDMI-out, LVDS, analog […]
