Embedded Systems Hardware & Software Trends for 2011

VDC Research – a US company specialized in technology market intelligence – recently released two reports about embedded systems trends for 2011. The first report focuses on hardware and the second on software. The first report entitled “Top 10 trends for the embedded hardware and systems market in 2011” listed the following trends: COMs gain traction as time-to-market accelerators for OEMs By combining COM express modules with off-the-shelf COMs, suppliers are able to offer several different configurations of CPU boards and leverage COMs’ interchangeable characteristics. CPU vendors can thus offer a fairly wide range of boards without incurring high design and inventory carrying costs. PC/104 module family under pressure Although VDC data projects the PC/104 family will experience a single-digit rebound from the low points of the recent recession, vendors will have to commit resources to develop newer strategies in order for this technology to remain viable. Otherwise, the recovery […]

LG Optimus 2X – First Dual Core NVidia Tegra 2 Smartphone

LG has just introduced the Optimus 2X (codenamed the LG Star), the first smartphone to run a dual-core processor namely Nvidia Tegra 2 @ 1GHz. The device will be initially available in Korea (Model: LG-SU660) in January 2011, and later in the year in Europe, then the rest of Asia (Model: LG-P990). LG Optimus 2X will be shipped with Android 2.2 upgradeable to Android 2.3 (Gingerbread). The phone features a 4-inch WVGA screen, 8GB of internal memory, microSD support (up to 32GB), HDMI output, Digital Multimedia Broadcasting (DMB), DLNA support, an accelerometer, a gyro sensor,  1080p MPEG-4/H.264 playback and recording and finally 2 cameras: an 8 megapixel back camera plus a 1.3 megapixel front camera for video calls. Please see the video below where the Optimus 2X is compared to the iPhone 4 and the Samsung Galaxy S. The LG Star is really the clear winner in terms of performance. […]

Building Archos Gen8 Source on Ubuntu 10.10

[ad#Google Adsense-Leaderboard] In a follow-up post of GPL Source code and SDE for Archos Gen8 Devices earlier today, here are the steps I followed to build the toolchain, kernel and root file system with buildroot on Ubuntu 10.10 Desktop version: Extract the source code: tar xzvf ../Downloads/gen8-gpl-froyo.tgz Install extra packages for the build: sudo apt-get install flex bison build-essential zip curl libmpfr-dev libmpfr1ldbl automake autoconf libtool gettext texinfo Run the build to generate the toolchain, kernel and root file system: cd gen8-gpl-froyo/buildroot sudo make Then wait for a while (It took 1h15 on my machine) to get the binary images: zImage (kernel) in buildroot/linux/arch/arm/boot rootfs.arm.squashfs (rootFS) in buildroot/binaries/uclibc

Unusual USB Devices in Linux Kernel

Some USB devices (especially cheap ones) are not fully compatible with the USB Stack and when you connect such devices to your target board, the kernel may output errors similar to the one below even though most other devices work perfectly. sd 3:0:0:0: SCSI error: return code = 0x10070000 end_request: I/O error, dev sda, sector 0 Buffer I/O error on device sda, logical block 0 sd 3:0:0:0: SCSI error: return code = 0x10070000 end_request: I/O error, dev sda, sector 8 Buffer I/O error on device sda, logical block 1 sd 3:0:0:0: SCSI error: return code = 0x10070000 end_request: I/O error, dev sda, sector 16 sd 3:0:0:0: SCSI error: return code = 0x10070000 end_request: I/O error, dev sda, sector 24 sd 3:0:0:0: SCSI error: return code = 0x10070000 It previously happened to us with a IDE to USB adapter based on Super Top Bridge ( VID: 0x14CD / PID: 0x6600).

Software Code Review Study and Best Practices

Many companies perform software development without code reviews – the systematic examination of source code intended to find and fix mistakes overlooked by the original developer – or at least without formal reviews. I’ve recently come across The Value and Importance of Code Review white paper from Klocwork who commissioned an independent company to survey IT professional. This paper shows code review practices have not changed much over the years even though software development have dramatically evolved. Here are the key findings of the study: Code reviews are valuable, but approaches tend not to be formal. Modern development is increasingly complex,  and code reviews are not keeping pace. (i.e. Code reviews are low priority tasks) Code reviews don’t always include the right people. (e.g. Architecture and QA Team are left out, only only software engineer are part of the review) Tools don’t play a significant role in reviews. (e.g. code […]
