Louis walked the last flight of stairs to the roof with his gear in tow.  Sebastian followed him and helped check the rigging.  Louis got his bearings on the edge of the roof while Sebastian checked the wind one last time.  The tell-tale strand of yarn on the handheld wind meter streamed backward and up as the LCD read the velocity.  The perfect time was… Now!  Louis pushed off and smoothly transitioned into his freefall form while pulling the release for the parachute.  As his body raced toward the terminal velocity of 55 … Read More → "FPGA BASE Jump"

Most engineers will agree that duct tape is an excellent multi-purpose tool.  This wonder product has been used for everything from giving tennis balls the feel of a cricket ball, to saving the Apollo 13 mission from certain disaster.  Engineers love good multi-purpose tools because of the sheer versatility that they offer; a good multi-purpose tool can help a creative engineer get themselves out of a real bind.

To hardware designers, FPGAs are also excellent multi-purpose tools.  No other “off-the-shelf” semiconductor can become so many different things to different people.  The super-versatile … Read More → "Duct Tape, FPGAs, and the Art of Making Great Multi-Purpose Tools"

The age of big, expensive, power-hungry FPGAs is now officially over.  Of course, FPGA companies still make devices with three (and even four) digit price tags.  The biggest, baddest chips will probably be at that price point for awhile.  But don’t be deceived.  There’s a revolution afoot, and it isn’t at the high end.  The capabilities of low-cost FPGAs are where the real action is today.

There’s nothing new about low-cost FPGAs either, of course.  They’ve been around for close to … Read More → "BOM Blast"

We’ll finally admit it.

Designing with FPGAs is hard.

We hear all the marketing pitches – you download the free software, plug in the development kit, push the sequence of “Go” buttons, and voila! The simulator plots out little waveforms. The synthesis tool thinks for about two seconds and says you met timing. Place and route successfully locates all six LUTs of the design and connects them together.  The bitstream blasts through the jtag port into your demo board.  You press the reset button.  There they are!  The … Read More → "Teaching them to Fish"

We’ve discussed the amazing potential FPGAs bring to DSP acceleration for years now.  We’re not alone, either.  FPGA vendors have pumped out trumped up performance specifications with dizzying claims as to the number of GMACs (Giga-Multiply-Accumulates per second) their hardware could execute.  So dizzying, in fact, that most of the potential customers got vertigo and fell to the floor without buying any FPGAs.

This was a problem for FPGA vendors – who quickly hooked up probes to the unconscious DSP dudes, downloaded their issues through virtual JTAG ports, and found out ( … Read More → "Dialing-in DSP on FPGA"

Those of us who go through engineering training arrive and depart with a wide range of expectations and purposes.  Some of us were just good at math and science as kids, and we followed that inertia into an engineering program with little thought of long-range lifestyle implications.  We simply chose the college program that most closely mimicked our favorite subjects in high-school and… voila – we popped out with an engineering degree.  During our last year of college, of course, the recruiters invaded the campus with well-rehearsed and elaborate spiels setting our salivary glands on … Read More → "Myth of the Technical Track"
