The Linux Embedded System Design Workshop for ARM and ARM+DSP covers the development of a generic ARM and ARM+DSP application.  The first two and a half days concentrate primarily on Linux/ARM development while the last day and a half focus on accelerating signal processing algorithms (ARM or DSP-based algorithms).  

While the lab exercises implement a generic audio/vido application, the skills learned in the course are applicable to a wide range of application spaces. The side benefit, though, is that we can see how the video peripherals on these devices (i.e.DaVinci DM6446) greatley accerlerate video applications and their development (allowing video to be used in systems where it may not have previously been practical. 

This course examins the software acrchitectures used with TU's various SOC processors: DM646x, DM3x, OMAP35x, AM35x, AM18x, AM37/DM37xx, and OMAP-L1xx.  

Beginning with an overview of the family and device architecture, this workshop builds a generic audio/video system which allows exploration of data input/output as well as creating Linux multi-threaded environments. Once data is passing through the system, we practice calling algorithms on that data - both local (ARM-based) algorithms, as well as remote (DSP-based) algorithms.  The workshop ends with an examination of packaging algorithms using DMA in algorithms, and an overview of DSPLink.

The workshop concentrates on many software components/libraries provided by Texas Instruments:

• Using Linux Device Drivers (PSP)
• Codec engine - algorithm & interprocessor-communication framework (VISA API)
• XDM - codec/algorithm packaging (akin to algo classes)  
• GNU Make and XDC build tools are briefly explored

  Testimonials of past workshop participants

      (Names and company information withheld for confidentiality)

"This workshop greatly reduces the learning curve and provides a good view of where to start and what is available."

"This workshop is wonderfully organized. The lab progression is excellent. It was a great experience."

 "This workshop has helped me get a complete grasp of the DaVinci. I have a board and have been coding it some before this point. The course helped solidify my understanding."  

"This workshop has taught me, in a very short time, all the things that the DaVinci technology can do for me. Now I have confirmation that our choice of DaVinci is an excellent match for our project needs."
