        Talk: 

        Powerful “System on a Chip” devices are inexpensive. Usually, they come with a version of Linux for support. This talk will be about using the ARM microprocessor in a System on Chip (SOC) configuration and how to program it using a “bare metal” configuration for embedded applications. The target for this talk is the Raspberry PI zero w. This talk will be broken down into five sections.

        (1) The assembly/C code that is required to initialize the interrupts, GPIOs, SPI, I2C, video core (VPU) and floating point math unit (FPU). (2) The software required to allow the programmer easy access to the GPIO ports. (3) Setting up the video processing unit and writing to the frame buffer. An example that plots the Mandelbrot set will be demonstrated. (4) Setting up the floating point unit and demonstrating how to do single instruction multiple data (SIMD) operations. An example that implements an 8 pole band-pass filter will be shown. (5) A simple operating system implemented as a cooperative multi-tasker will be shown.

        • Non-member guests are always welcome.

          Talk: The Holiday Season is just around the corner. What Hi-Tech consumer items have impressed you? Bring your favorite one and be prepared to discuss it’s technical merits. Also, be prepared to give give a brief introduction to what you do (“Elevator Speech”).  This is your opportunity to discuss your company, or your consulting expertise while having fun.

          Speaker: Dennis Bahr, PhD, VP of R&D at HelionX, LLC has a long history of Research and Develoment in Biomedical systems. He is also the founder and president of Bahr Management, Inc., a company that develops and helps bring to market innovative medical devices for use in the cardiovascular, trauma, life support, and surgical markets. He also spends time doing research, such as designing new technologies, developing new mathematical algorithms, and doing computer based modeling. Dennis enjoys being involved with Science, especially developing new ideas and theories. One great enjoyment is developing new mathematical methods and algorithms to solve complex problems that people have said couldn’t be solved.

  • Meeting Reviews

     October Section Meeting/Joint UW-Madison Student Branch Meeting: (Photos  of the event are available on the links by Tom Kaminski and Charles Cowie.) The talk was preceded by a display of some high-end vehicles equipped with autonomous driving systems. The vehicles were on the walk between Lot 17 and Engineering Hall on a path with a lot of student foot traffic, generating an additional draw to the meeting.  The meeting was well attended and Bob Neff gave a presentation that covered the history of autonomous vehicles up to the present. Bob also discussed several of the challenges facing adoption of the technology. Despite the US Government Department of Transportation’s early standards, auto manufacturers were slow to adopt to the technology in a “chicken and egg” struggle. Who would build a car to drive on a modern highway if there were no highways? Advances in technology have now made it possible to drive autonomously on modern roads, but as of today, no country in the world allows a driverless auto to operate on public highways.

    October Special Meeting: Dr. James Smith, Emeritus Professor of Electrical and Computer Engineering, gave a talk to the College of Engineering Students on the topic “Space-Time Computing and the Brain”. Dr. Smith based his talk on the advances in the neuroscience community that have been describing how the brain operates and claimed that Computer Architects should be shamed by the advances in the neuroscience community that have been ignored by the engineering community. He challenged the Computer Architects in the audience to quit “chasing the bright, shiny object” of deep learning neural networks and get to work on the more significant problem of finding a way to mimic the way the brain really computes.

    Dr. Smith showed a taxonomy of the current neural network models and introduced the time-space model. He then went on to motivate his discoveries by showing a simple combinatorial network that transforms a vector of zero’s (binary digits) to a vector of zero’s, yet sorts the arrival times of the 1 to 0 transitions in sequence.  He then proposed a mathematical algebra based on “Space-Time” computing and showed how it closely mimics true neural networks. Dr. Smith used introduced space-time algebraic primitives to build neural networks that behaved in the manner as all of the current models based on neuroscience research. Finally, he proposed that these primitives could be built from existing CMOS on silicon technology without the need to invent new device technology.


    Dr. Jim Smith Talk
    November Life Member Affiliate Group Meeting:  Steve Schultheis gave a detailed and informative talk on the history of musical instruments and the evolution of electronic instruments, some of which attempted to mimic the traditional instruments and some of which created unique sounds of their own. Steve spent a good amount of time discussing the details of a simple microphone, showing how that device evolution over time did not substantially improve on the earliest devices. He discussed a number of trade offs in the design of the electronic instruments such as the “sampled” (huge files required) verses “simulated” (huge computational requirements) approaches to instruments. While the sampling technique works well for percussion instruments, such as drums, pianos require huge files sizes, on the order of a half-terabyte.  Sampling has little hope of duplicating the interaction of multiple keys pressed at once. During the presentation, Steve used his programmable equipment to show how different sounds could be synthesized. Steve finished the presentation with a short concert, playing a jazz tune. A printed copy of Steve’s Presentation is available here.

      • Upcoming Meetings

        November Joint EMB/Student Branch Meeting — This meeting is open to the entire section, especially to those interested in embedded systems.  Dennis Bahr has been developing portable biomedical instruments using the Raspberry Pi Zero W, a $10 SoC on a board with WiFi and Bluetooth. Dennis has figured out how to dispense with the usual Linux operating system and get access to both the Graphics Processing Unit (GPU) and Floating Point Unit (FPU).  The result is a lower power, real-time system that can use the Open Sourced development tools developed for the Linux version.

        December ECN Meeting: This is an opportunity to pitch your consulting/entrepreneur skills while having fun discussing your favorite current technology. You might just get a few ideas for the upcoming “giving” season.
