ARM big.LITTLE Technology

big.TITTLE is a technology designed by ARM. With performance and data consumption predictied to increase by eight times, a furture proofed energy efficient solution had to be found.

By using multiple processors that are developed for different energy and performance budgets, big.TITTLE provides optimum performance and maximum efficiency. The first big.LITTLT solution will pair the ARM Cortex-A15 process with ARM Cortex-A7 process (download "How IT Works" in PDF format). This will be followed by roadmap of new Cortex processors that build on big.LITTLE making it an important innovation for furture mobile devices.

Ten Things to Know About big.LITTLE:

1. Can you switch on all the cores at once?
2. Is the software similar to existing mechanisms like DVFS and SMP scheduling?
3. Can it run with Android™ today, with no changes to Android?
4. How does big.LITTLE enable higher performance?
5. How does big.LITTLE enable greater energy savings than just lowering the voltage?
6.  Are the power savings available from big.LITTLE significant at the system level?
7. Can big.LITTLE save power on high performance tasks too?
8. How much user level code needs to be changed to support big.
9. Can there be a different number of big and LITTLE cores?
10. I hear it's hard to use... how complicated is it?

A Gentle Introduction to Embedded Systems Programming

Want to do some embedded software? Or worse, did you get handed a project and just want to know what is going on? There are some concepts you'll need to understand: volatile variables, hardware registers, static keywords, memory maps, bit manipulation and function pointers, oh my! This webcast walks step-by-step through the most important concepts a software engineer will need to get started on the path to embedded systems.

Qt application development on the Beaglebone, an ARM Embedded Linux system

Part 1 - Beaglebone: LCD Touchscreen GUI Applications for Embedded Linux
This is the first video in a set of three on Qt application development on the Beaglebone or any other embedded Linux device. This video introduces the LCD module that I used, reviews it and then discusses how you can install it and develop very basic onboard GTK GUI applications. This leads to the second video where I set up a full toolchain for Qt application development under embedded Linux (Qt for embedded devices) and then in the final video I demonstrate an example application that uses an accelerometer and LED to act as output/input devices and I provide the full source code.

Part 2 - Beaglebone: Qt Creator for C++ ARM Embedded Linux Development
This is the second video in a set of three on Qt application development on the Beaglebone or any other embedded Linux device. The first video introduces the LCD module that I used and this video is where I set up a full toolchain for C++ Qt application development under embedded Linux (Qt for embedded devices). This toolchain allows us to cross compile Qt applications for the Beaglebone, deploy the applications directly to the beaglebone with a single click and even use remote debugging using gdbserver to diagnose any problems with our applications. The main use of this platform is for GUI application development when a LCD module, or external display is present.

In the final video I demonstrate an example application that uses an accelerometer and LED to act as output/input devices and I provide the full source code.


Thad Failor (via comments below) provides some information on how to deal with the requirement to execute . /usr/local/angtrom/arm/environment-setup in advance of starting QtCreator. The steps are: 
- Open Qt Creator 
- Open your project 
- Click Projects under [Your Beaglebone Kit] 
- Click Build 
- Scroll down to the bottom and click details 
- Click on Batch 
- Edit Paste the contents of the ". /usr/local/angstrom/arm/enviro­­nment-se­tup" removing any of the "export" commands.

Part 3 - Beaglebone: Example Qt Embedded Linux Application
This is the third video in a set of three on Qt application development on the Beaglebone or any other embedded Linux device. The first video introduces the LCD module that I used and the second video is where I set up a full toolchain for C++ Qt application development under embedded Linux (Qt for embedded devices). This toolchain allows us to cross compile Qt applications for the Beaglebone, deploy the applications directly to the beaglebone with a single click and even use remote debugging using gdbserver to diagnose any problems with our applications. The main use of this platform is for GUI application development when a LCD module, or external display is present.

In this the final video in this series I demonstrate an example application that uses an accelerometer and LED to act as output/input devices and I provide the full source code. I explain how the source code is structured and how the physical circuit was configured.

The source code is available at the Linux prompt by typing:
git clone git://github.com/derekmolloy/beagleboneQ­T.git

You can download the PyPy 2.1 beta release here: http://pypy.org/download.html

What is PyPy?

PyPy is a very compliant Python interpreter, almost a drop-in replacement for CPython 2.7.3. It's fast due to its integrated tracing JIT compiler. This release supports x86 machines running Linux 32/64, Mac OS X 64 or Windows 32. Also this release supports ARM machines running Linux 32bit - anything with ARMv6 (like the Raspberry Pi) or ARMv7 (like Beagleboard, Chromebook, Cubieboard, etc.) that supports VFPv3 should work. Both hard-float armhf/gnueabihf and soft-float armel/gnueabi builds are provided. armhf builds for Raspbian are created using the Raspberry Pi custom cross-compilation toolchain based on gcc-arm-linux-gnueabihf and should work on ARMv6 and ARMv7 devices running Debian or Raspbian. armel builds are built using the gcc-arm-linux-gnuebi toolchain provided by Ubuntu and currently target ARMv7.

Simulator for Arduino

Simulator for Arduino v0.98 Floating Point issue, Open browser, Simulate LCD

Here is a quick run through of version 0.98 of Simulator for Arduino. All the test sketches can be found in the Samples folder. First the floating point decimal symbol setting is reviewed - the decimal symbol must be set to a period or . otherwise floating point number will give errors.

Then a series of sketches is tested ending up with a demo of the new LCD simulation graphic. This demo shows how the CGRAM characters are setup and shows the official Arduino example running with a stick figure person waving his hands.
