Texas Instruments AM387X Sitara ARM Cortex A8 Microprocessors

Texas Instruments (TI) has introduced three new AM387x ARM Cortex-A8 microprocessors (MPUs): AM3871, AM3872 and AM3874. TI says these MPUs offer integration of the ARM Cortex-A8 core, peripherals for high-bandwidth connectivity (SATA, D-CAN, PCI Express (PCIe), Gigabit Ethernet switch and more), 3D graphics for enhanced GUIs and display subsystems for camera connectivity and viewing. The AM387x ARM Cortex-A8 MPU can connect to and control IP and CAN networks, HD displays, keyboard, mouse, PC, SD card and various general purpose peripherals, all via one highly integrated processor in an industrial automation application controlling a production line and a high-speed, shared data bus allows for reduced communication overhead and quick access to shared data, which results in reduced chip count, discrete memory costs and printed circuit board (PCB) space compared to separate solutions. Those MPUs are targeted at a variety of fanless applications such as: single board computing, network and communications processing, […]

OpenCL (Open Computing Language) Overview and SDKs

OpenCL (Open Computing Language) is a multi-vendor open standard for general-purpose parallel  programming of heterogeneous systems that include CPUs, GPUs and other processors. OpenCL provides a uniform programming environment for software developers to write efficient, portable code for highperformance compute servers, desktop computer systems and handheld devices. OpenCL standard is managed and defined by the Khronos Group. The latest version (OpenCL 1.1) was ratified by the Khronos Group on the 14th of June 2010 and adds significant functionality for enhanced parallel programming flexibility, functionality and performance including: Host-thread safety, enabling OpenCL commands to be enqueued from multiple host threads. Sub-buffer objects to distribute regions of a buffer across multiple OpenCL devices. User events to enable enqueued OpenCL commands to wait on external events. Event callbacks that can be used to enqueue new OpenCL commands based on event state changes in a non-blocking manner. 3-component vector data types. Global work-offset which […]

Fix for Lost Bookmarks in Firefox 6

Right after a disk defragmentation, my colleague suddenly had an error message in Firefox “The bookmarks and history system will not be functional because one of Firefox’s files is in use by another application. Some security software can cause this problem” and all history and bookmarks were gone. You can use the “Learn More” button to go to the page The bookmarks and history system will not be functional to find solutions: Solution 1: Restart your computer Solution 2: Create a new places database by renaming  places.sqlite Unfortunately none of those solutions worked for us. But we fixed it by following Solution 2 and deleting some extra files (in green) as follows: At the top of the Firefox window, click on the Firefox button, go over to the Help menu (on Windows XP, click on the Help menu) and select Troubleshooting Information. The Troubleshooting Information tab will open. Under the […]

Windows 8 NFC (Near Field Communication) Demo

A few months back, I would have never thought I would post about Microsoft and Windows in an embedded software blog, except for the rare mention of Windows CE or Windows Embedded products. But it now seems Windows 8 will actually focus on products that were previously almost exclusively ARM based such as tablets and smartphones. I have already posted about Windows 8 Tablet and Smartphones demo at the build conference and today I’ll discuss a little bit about NFC support in Windows 8. Windows 8 will support NFC (Near Field Communication) with NXP PN544 NFC controller chip. NXP PN544 is also the NFC solution used in the Windows 8 tablets, made by Samsung, which are being distributed to attendees of Microsoft’s Build Windows conference 2011. The NFC use cases available with Windows 8 include: Windows 8 device pairing (e.g. Bluetooth headsets and speakers) Data sharing (e.g. digital business cards) […]

Window 8 ARM Platforms at Build Conference 2011

Yesterday, I mentioned the Nvidia Tegra 3 tablet running Windows 8 which is currently showcased at Build Conference 2011 and they also had a Tegra 3 laptop running Windows 8. But Nvidia was not the only company showing off ARM based processors running Windows 8. There were at least 2 other companies, namely Qualcomm and Texas Instruments. Qualcomm showcased a Snapdragon MSM8660 (Dual core 1.2 GHz) Tablet running Windows 8 and announced that the first batch of Windows 8 PC will be based on the Snapdragon processor. Texas Instruments brought a Windows 8 Tablet based on OMAP4430 (dual core 1 GHz) developed in partnership with Quanta.

Most Engineers have Multicore/Multiprocessor Experience

In a recent blog post entitled “Engineers’ Multicore/Multiprocessor Experience Improving” , VDC research revealed a survey showing that more and more engineers are gaining experience working on multicore or multiprocessor projects. In their 2011 survey, there are now only 32% of engineers who have never worked on projects based on multicore and/or multiprocessor versus 45% in 2010. VDC Research questions the the factors that are driving engineers’ expanding experience with multiprocessing, such as  the increasing availability and affordability of multicore processors, advancements in processor technology, the effectiveness of ISVs efforts around educating the engineering community about the use of multicore or the continued maturation of software solutions that enable parallel programming. But I believe it’s all of the above. There are now many cost effective multicore processors for embedded systems (mainly thanks to ARM). Some of them have low cost development platforms that attract more developers. For device where battery […]

Can You Really Boost your Wifi Router Signal with a Beer Can?

I’ve recently come across an interesting and amusing story entitled “Boost Your WiFi Signal Using Only a Beer Can”  on discovery channel website. I’ve said to myself that I’ve got to try with my WiFi router. The interesting part is that my WiFi router (TP-LINK TL-WR940N) has 3 antennas, so I had to diligently drink three beer cans (LEO brand,  the best local beer in Thailand). Once this was done, I had all that I needed, besides a pair of scissors, a utility knife and some double faced tape. The next step was to clean the beer cans, let them dry and cut the bottom and top of the beer cans as described on discover channel blog post. There is no dotted red line on LEO beer cans, but there are yellow horizontal lines that make this can perfect for the job. After less than 5 minutes of hard work, […]

Intel and Google to work on Android for Atom

Intel officially announced it will collaborate with Google to optimize the Android OS for Intel’s Atom processor platform in order to help Intel entering the smartphone market. In his keynote on the 13th of September – the first day of the Intel Developer Forum 2011 – Intel CEO Paul Otellini announced the partnership with Google to support Android on Atom processors and said the first Intel-based smartphones will be available in the first half of 2012. Paul Otellini demoed Intel’s Android smartphone reference platform running Android 2.3 (Gingerbread). The phone is 9.5mm thick, had an HDMI output, NFC support and features Intel’s 32nm Medfield processor which is said to include a newer generation GPU. Intel also showed off the new ISP (Image Signal Processor) capabilities in Medfield which is capable of capturing up to 20 fps at 1600 x 1200. However, the reference platform could only deliver 10 fps from […]
