MIPS Mulls Microcontrollers

The processor IP market isn’t just about processors anymore.  A number of companies make outstanding processor core IP, but getting design teams to engineer those into products requires a lot more than a snappy Dhrystone number.  Product developers want to make sure that their designs are backed up by a rich portfolio of development tools, operating system and middleware support, and compatible peripheral IP.  MIPS sells some of the fastest, lowest power, most widely used processor cores on the market.  They have a strong market share in devices like set-top boxes and consumer … Read More → "MIPS Mulls Microcontrollers"

Duct Tape, FPGAs, and the Art of Making Great Multi-Purpose Tools

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"

BOM Blast

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"

GMACs GAP

Multiplication is our big problem.  We need to multiply.  We need to multiply integers. We need to multiply fixed-point numbers. We need to multiply floating point numbers. We need to multiply complex numbers.  But, we also need to multiply other things.  In designing embedded systems, we constantly need to multiply our productivity.

Over the past 40 years, Moore’s Law has given us exponential improvement on the three “Ps”: Power, Performance, and Price.  Transistor counts have reached the billions, frequencies have raced into the Gigahertz, and the power consumed for … Read More → "GMACs GAP"

Teaching them to Fish

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"

Industrial Revolution

The industrial automation and control field is an ever-changing mish-mash of protocols, standards, and conventions.  Recently, there has been a wave of replacement sweeping the networking standards space as proprietary and legacy standards give way to more cost-effective off-the-shelf solutions such as Ethernet.  The advantages of Ethernet-based networking are probably obvious – high availability of low-cost, high-reliability infrastructure, built-in future-proofing, very high bandwidth by industrial control standards, and the ability to integrate more smoothly with other types of equipment that are not part of the traditional industrial automation ecosystem.

As these standards shift, however, we … Read More → "Industrial Revolution"

Dialing-in DSP on FPGA

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"

From Servers to Smartphones

The rack of heavy-iron blade servers whirrs away, dishing up data and mashing myriad algorithms for hundreds of users throughout the corporate campus.  Most of them have no awareness whatsoever of the physical location of the computing resources doing their dirty work.  Day by day and week by week the blades and racks are removed, replaced, upgraded, and re-tasked.  One capacity increase is accomplished by stacking in additional blades, the next by replacing an outdated rack with a new, smaller one with fewer blades and vastly more processing power.

Those of us who have … Read More → "From Servers to Smartphones"

Myth of the Technical Track

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"

Happy Birthday

Embedded Technology Journal turns a terrific two years old today.  What does this mean?  For us, two years of your loyal patronage means that we’re doing something right.  It means that we were right about you, our readers – that engineers are intelligent, worldly, interesting people who want more than a datasheet, a press release, or a marketing pitch to satisfy their curiosity about the industry in which they work.  Surviving and thriving for two years in the competitive world of publishing shows that our approach to technology journalism – chronicling the technological … Read More → "Happy Birthday"
