Lattice Semiconductor has developed two power-saving IP cores intended for use in smartphones and mobile devices. Known as ‘Voice Solution’ the two IPs are: Voice Command supporting hands-free and always-on applications, and Voice Recognition which improves the user experience by enhancing security and reducing false trigger inputs. They essentially act as a processing front-end, allowing the main processor to remain in low power dormant mode until voice commands have been processed and recognized by the Lattice Voice Processor.

Trandi blogged about his RC servo and stepper motor project. He writes:

For those interested in reproducing this example:
The board is called “EP2C5 Mini Board” and has a EP2C5T144C8 Cyclone II FPGA on it
I used a standard, 9grams micro RC Servo
I used a 28BYJ-48 stepper motor and it’s driver (you can purchase these as a bundle for very cheap on dealextreme or banggood)
I used the free edition of Quartus II from Altera, version 13.0 SP 1 (be careful, later versions do not support Cyclone II FPGAs anymore)
I created a simple project, pasted all this code as a single module (it would of course be cleaner to separate the RC Servo and stepper control code into independent modules)
made the “Top level entity” in the General configuration page equal to “counter” (the name of my module)
used the Pin Planner to assign the inputs/outputs as follows:

I bought Avnet’s $49 Spartan 3A development board but it was discontinued not long afterward – right about the time when I decided I needed a few dozen more. I’ve since done some extensive research (thanks, Google!) to find a comparable thrifty thrill.

When choosing a development board, consider what you get with it and what you want to use it for. FPGAs are ideal for use with high speed peripherals, and in general it is much easier to buy a board that contains the part you want, rather than trying to add one on later (and inevitably giving up and upgrading to a more capable board).

PyroElectro.com proudly presents their new contest:

View the Pyro Propeller Clock POV Project to learn more about the concept Persistence of Vision (POV) – a phenomenon where an afterimage persists for roughly one twenty-fifth of a second on the retina after the stimulus that produced it is removed.

Build an original electronic device demonstrating POV and photograph in action in a darkened environment. You may use any electronic parts desired as long as the POV signals are driven by either an FPGA or CPLD.

Submit your entry to contests@pyroelectro.com with the subject line “PyroElectro POV Contest.” Your entry must contain two photos of the device – one of its components in a well-lit environment and one of it in action in a darkened environment – as well as a circuit diagram and the VHDL code to run the device.

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

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, RS232 and Tx/Rx. Power requirements of the SOM are typically 3 to 5 W.

Whether engineer, hobbyist, or maker, we’ve happily watched as chipmakers and third parties alike have come to their senses in recent years and cooked up a smorgasbord (smorgasboard?) of low-cost microcontroller devboards – in some cases, very low cost, like TI’s $4.30 MSP430 board. More recently, we’ve seen ARM Cortex kits for $10-$50, the flowering of the whole Arduino ecosystem, and of course, the Raspberry Pi, starting at $25. It’s microcontroller heaven.

Those of us wanting a cheap “in” to the FPGA world have been less lucky. But the times, they are a changin’. Many FPGA devkits, from both chipmakers and third parties, have broken – or downright shattered – the $100 barrier, opening the door to low-cost FPGA prototyping, education, hobby projects, and so on.

Follow me as I explore this brave new world of affordable FPGA learning and design. I’ve acquired a representative selection of bargain-priced boards, and will be reviewing each, not just on paper, but by actually creating projects with it.

FPGA boards under $100: Introduction - [Link]

pyroelectro.com just started an online course, An Introduction To FPGA And CPLD, through uReddit.com.

This course is meant to create a pathway into learning about FPGA and CPLD electronics, for people who are scared of the code, tools and general trickery that usually comes with it. A hands-on approach is taken in this course through a combination of lecture and experimentation to teach you about the different features of both the development tools and languages used in the world of FPGA. Additionally, visuals are used throughout lectures like step-by-step schematic building and line-by-line code explanations so that everything gets explained.

Comes with all the hardware and software you need to quickly get your FPGA project going. Now you can focus on the real engineering.

When we came up with our board’s design, we looked at what was available in other boards on the market and enhanced it.

Our kit is small, much smaller than the closest thing on the market,it’s smaller than a credit card at only 1.8 in x 3.0 in. That means you can put it inside some pretty small projects. (Here’s something to get you thinking, by 2025 the cost of putting one pound into space is expected to be just $100.)

And our kit is bread board friendly, so you can quickly connect it to a shield or to a bread board.

Now, there’s a handful of other broads with many of these features on the market, but our miniSpartan6+ costs around half of what its closest competitor does.

The hardened single-precision floating point DSP blocks included in Arria 10 and Stratix 10 devices are based on Altera’s variable precision DSP architecture. Unlike traditional approaches that implement floating point by using fixed point multipliers and FPGA logic, the hardened floating point DSP blocks eliminate nearly all the logic usage required for existing FPGA floating-point computations. The technology enables Altera to deliver up to 1.5 TeraFLOPs DSP performance in Arria 10 devices and up to 10 TeraFLOPs DSP performance in Stratix 10 devices. This now gives DSP designers the choice of either fixed or floating-point modes. The floating point blocks are backwards compatible with existing designs.
