Embedded SOM with Linux-Based RTOS

National Instruments has introduced an embedded system-on-module (SOM) development board with integrated Linux-based real-time operating system (RTOS).NIsom

Processing power in the 2” x 3” SOM comes from a Xilinx Zync-7020 all programmable SOC running a dual core ARM Cortex-A9 at 667 MHz. A built-in, low-power Artix-7 FPGA offers 160 single-ended I/Os and Its dedicated processor I/O include Gigabit Ethernet USB 2.0 host, USB 2.0 host/device, SDHC, RS-232, and Tx/Rx. The SOM’s power requirements are typically 3 to 5 W.

The SOM integrates a validated board support package (BSP) and device drivers together with the National Instruments Linux real-time OS. The SOM board is supplied with a full suite of middleware for developing an embedded OS, custom software drivers, and other common software components.

The LabVIEW FPGA graphical development platform eliminates the need for expertise in the design approach using a hardware description language.

SDK for OpenCL Dev Flow

Altera Corp. has simplified a programmer’s ability to accelerate algorithms in FPGAs. The Altera SDK for OpenCL version 14.0 includes a programmer-familiar rapid prototyping design flow that enables users to prototype designs in minutes on an FPGA accelerator board. Altera, along with its board partners, further accelerate the development of FPGA-based applications by offering reference designs, reference platforms and FPGA development boards that are supported by Altera’s OpenCL solution. These reference platforms also streamline the development of custom FPGA accelerators to meet specific application requirements.

Altera is the only company to offer a publicly available, OpenCL conformant software development kit (SDK). The solution allows programmers to develop algorithms with the C-based OpenCL language and harness the performance and power efficiencies of FPGAs. A rapid prototyping design flow included in the Altera SDK for OpenCL version 14.0 allows OpenCL kernel code to be emulated, debugged, optimized, profiled and re-compiled to a hardware implementation in minutes. The re-compiled kernels can be tested and run on an FPGA immediately, saving programmers weeks of development time.

Altera and its board partners further simplify the experience of getting applications up and running using FPGA accelerators by offering a broad selection of Altera-developed reference platforms, reference designs and FPGA accelerator boards. Altera provides a variety of design examples that demonstrate how to describe applications in OpenCL, including OPRA FAST Parser for finance applications, JPEG decoder for big data applications and video downscaling for video applications.

Design teams that want to create custom solutions that feature a unique set of peripherals can create their own custom FPGA accelerators and save significant development time by using Altera-developed reference platforms. The reference platforms include an SoC platform for embedded applications, a high-performance computing (HPC) platform and a low-latency network enabled platform which utilizes IO Channels.

One notable enhancement is production support for I/O Channels that allow streaming data into and out of the FPGA as well as kernel channels allowing the result reuse from one kernel to another in a hardware pipeline for significantly higher performance and throughput with little to no host and memory interaction. Another enhancement is production support for single-chip SoC solutions (Cyclone V SoC and Arria V SoC), where the host is an embedded ARM core processor integrated in the FPGA accelerator.

Altera’s SDK for OpenCL allows programmers to take OpenCL code and rapidly exploit the massively parallel architecture of an FPGA. Programmers targeting FPGAs achieve higher performance at significantly lower power compared to alternative hardware architectures, such as GPUs and CPUs. On average, FPGAs deliver higher performance at one-fifth the power of a GPU. Altera’s OpenCL solutions are supported by third-party boards through the Altera Preferred Board Partner Program for OpenCL. Visit www.altera.com/opencl.

The Altera SDK for OpenCL is currently available for download on Altera’s website (www.altera.com/products/software/opencl/opencl-index.html). The annual software subscription for the SDK for OpenCL is $995 for a node-locked PC license. For additional information about the Altera Preferred Board Partner Program for OpenCL and its partner members, or to see a list of all supported boards and links to purchase, visit the OpenCL section on Altera’s website.

Robotics, Hardware Interfacing, and Vintage Electronics

Gerry O’Brien, a Toronto-based robotics and electronics technician at R.O.V. Robotics, enjoys working on a variety of projects in his home lab. His projects are largely driven by his passion for electronics hardware interfacing.

Gerry’s background includes working at companies such as Allen-Vanguard Corp., which builds remotely operated vehicle (ROV) robots and unmanned ground vehicles (UGVs) for military and police bomb disposal units worldwide. “I was responsible for the production, repair, programming and calibration of the robot control consoles, VCU (vehicle control unit) and the wireless communication systems,” he says.

Gerry recently sent Circuit Cellar photos of his home-based electronics and robotics lab. (More images are available on his website.) This is how he describes the lab’s layout and equipment:

In my lab I have various designated areas with lab benches that I acquired from the closing of a local Nortel  R&D office over 10 years ago.

All of my electronics benches have ESD mats and ground wrist straps.  All of my testing gear, I have purchased on eBay over the years….

PCB flip rack

To start, I have my “Electronics Interfacing Bench” with a PCB flip-rack , which allows me to Interface PCBs while they are powered (in-system testing). I am able to interface my Tektronix TLA715 logic analyzer and other various testing equipment to the boards under test. My logic analyzer currently has two  logic I/O modules that have 136 channels each. So combined, I have 272 channels for logic analysis. I also have a four-channel digital oscilloscope module to use with this machine. I can now expand this even further by interfacing my newly acquired expansion box, which allows me to interface many more modules to the logic analyzer mainframe.

I also have a soldering bench where I have all of my soldering gear, including a hot-air rework station and 90x dissecting microscope with a video interface.

My devoted robotics bench has several robotic arm units, Scorbot and CRS robots with their devoted controllers and pneumatic Interface control boards.

On my testing bench, I currently have an Agilent/HP 54610B 500-MHz oscilloscope with the GPIB to RS-232 adapter for image capturing. I also have an Advantest model R3131A 9 kHz to 3-GHz bandwidth spectrum analyzer, a Tektronix model AFG3021 function generator, HP/Agilent 34401A multimeter and an HP 4CH programmable power supply. For the HP power supply, I built a display panel with four separate voltage output LCD displays, so that I can monitor the voltages of all four outputs simultaneously. The stock monochrome LCD display on the HP unit itself is very small and dim and only shows one output at a time.

Anyhow, my current testing bench setup will allow me to perform various signal mapping and testing on chips with a large pin count, such as the older Altera MAX9000 208-pin CPLDs and many others that I enjoy working with.

And last but not least… I have my programming and interfacing bench devoted to VHDL programming, PCB Design, FPGA hardware programming (JTAG), memory programming (EEPROM  and flash memory), web design, and video editing.

Interfacing bench and "octo-display"

Interfacing bench and “octo-display”

I built a PC computer and by using  a separate graphics display cards, one being an older Matrols four-port SVGA display card; I was able to build a “octo-display” setup. It seamlessly shares eight monitors providing a total screen resolution size of 6,545 x 1,980 pixels.

If you care to see how my monitor mounting assembly was built, I have posted pictures of its construction here.

A passion for electronics interfacing drives Gerry’s work:

I love projects that involve hardware Interfacing.  My area of focus is on electronics hardware compared to software programming. Which is one of the reasons I have focused on VHDL programming (hardware description language) for FPGAs and CPLDs.

I leave the computer software programming of GUIs to others. I will usually team up with other hobbyists that have more of a Knack for the Software programming side of things.  They usually prefer to leave the electronics design and hardware production to someone else anyhow, so it is a mutual arrangement.

I love to design and build projects involving vintage Altera CPLDs and FPGAs such as the Altera MAX7000 and MAX9000 series of Altera components. Over the years, I have a managed to collect a large arsenal of vintage Altera programming hardware from the late ’80s and early ’90s.  Mainly for the Altera master programming unit (MPU) released by Altera in the early ’90s. I have been building up an arsenal of the programming adapters for this system. Certain models are very hard to find. Due to the rarity of this Altera programming system, I am currently working on designing my own custom adapter interface that will essentially allow me to connect any compatible Altera component to the system… without the need of the unique adapter. A custom made adapter essentially.  Not too complicated at all really, it’s just a lot of fun to build and then have the glory of trying out other components.

I love to design, build, and program FPGA projects using the VHDL hardware description language and also interface to external memory and sensors. I have a devoted website and YouTube channel where I post various hardware repair videos or instructional videos for many of my electronics projects. Each project has a devoted webpage where I post the instructional videos along with written procedures and other information relating to the project. Videos from “Robotic Arm Repair” to a “DIY SEGA Game Gear Flash Cartridge” project. I even have VHDL software tutorials.

The last project I shared on my website was a project to help students dive into a VHDL based VGA Pong game using the Altera DE1 development board.
