Unconventional Touch

Funny how we have dual expectations when it comes to our hands. Give us a workshop and some tools, and we’ll craft a finely-honed wooden object using pressure to sand, gingerly holding nails in place so as not to end up with blackened thumbnails, and convolving fine finger movements with the delicate response of tiny brush bristles to paint intricate detail. Give us paper and a pen or brush, and we’ll create nuanced calligraphy that pleases and informs. Give a skilled dentist some scary-looking steel tools, and he or she will place them – hopefully – exactly where needed … Read More → "Unconventional Touch"

A Mark on the Bench

Writing benchmarks is a lonely endeavor. It’s kind of like being a referee or an umpire. Everybody wants a good and fair benchmark, but “good” and “fair” are both open to interpretation, and whoever comes out on the short end of the evaluation is sure to howl and squeal.

The patient souls at EEMBC (Embedded Microprocessor Benchmark Consortium) have been dealing with this problem for well over a decade. They’ve produced a number of different benchmarks that measure any number of vital system parameters, all with the goal of helping programmers and engineers choose the … Read More → "A Mark on the Bench"

Going Mobile with Solar

Batteries are the bane of portable device design. 

Just about every portable or mobile device or system that does anything interesting – that is, anything that would require a “real” chip like a processor or FPGA, or anything that does meaningful real-world interaction like drive a display or spin a motor – needs a significant amount of power. When you can’t plug into the wall or the grid, your options are pretty narrow. The essence of your design becomes a tradeoff between the capability and longevity of your device and battery size, weight, and … Read More → "Going Mobile with Solar"

MRAM Momentum

IEDM happened last month. If you haven’t been there, it’s the go-to place for the most detailed work done on the most advanced and obscure ideas for making ever-smaller electronics. There are a million things covered, most requiring a fair bit of detailed knowledge to be understood. Meaning that no one could grasp all of the papers being presented.

For those of us non-practitioners, add the practical reality of non-English speakers (can’t complain about that in a global industry – I’m lucky they’re using my language) speaking into microphones in giant echoey rooms … Read More → "MRAM Momentum"

Beyond Physical: Solving High-end FPGA Design Challenges

The advantages of using programmable logic to get electronic products to market quickly with less risk and cost are well known and recent market drivers have shifted even further in their favor; new economic realities coupled with changing consumer behavior, shorter product life cycles, richer feature sets, and faster upgrades, to name a few. In step with these demands, high-end FPGAs are now architected using geometries down to 40nm and with capacities of up to five million equivalent ASIC gates. They include performance optimized I/O’s and dedicated DSP … Read More → "Beyond Physical: Solving High-end FPGA Design Challenges"

Fast, Efficient RTL Debug for Programmable Logic Designs

In a typical FPGA design flow, most designers work from a written specification that contains architectural level drawings defining the major logic blocks, interfaces, and busses. The design manager begins to partition functionality based on the diagrams and to assign development based on the block’s functional descriptions. Each block is coded individually and may be simulated in a block-specific test bench. The team assembles the blocks into a device-level file where the ports are pins on the target device. The design is then ready to be compiled for simulation initiating the … Read More → "Fast, Efficient RTL Debug for Programmable Logic Designs"

The Great Divide: Why Next-Generation FPGA Designs will be Hierarchical and Team-Based

As field-programmable gate arrays (FPGAs) have grown in capacity, complexity and performance, their associated design and verification tools, infrastructures and methodologies have struggled to keep up. Today’s FPGAs may contain the equivalent of millions of logic gates and run hundreds of thousands of lines of embedded software. Such designs may involve multiple hardware design teams, software development teams and verification teams located around the globe. In order to address designs of this size and complexity it is necessary to employ what is known as hierarchical team-based design.</ … Read More → "The Great Divide: Why Next-Generation FPGA Designs will be Hierarchical and Team-Based"

Degenerates

“I need a brush.”

What would you do given such instruction by someone to whom the response, “Can you be more specific, please?” would be considered inappropriate? It’s a hard request (or demand) to satisfy if you know absolutely nothing about his or her intent. It’s almost as bad as the “Bring me a rock” theory of management, except that that’s simply a way of ensuring that your employees are never quite sure if they’re doing the right thing, and so they remain nervous and stressed; putty in your hands. No, in this … Read More → "Degenerates"

Economics 201

Three thousand dollars is lot to pay for a radio.

A friend of mine recently bought herself a nice new car. Not Rolls-Royce or Ferrari nice, but more in the Mercedes/Jaguar/Lexus category. And one of the optional upgrades she decided to spring for was a $3000 “Premium Comfort” package. Being both an engineering nerd and a car nut, I was curious about what actually went into this $3K bundle of goodies.

From what I could tell, it was mostly just firmware upgrades for little things like the keyless entry, cruise control, or GPS features. … Read More → "Economics 201"

Looking Right Back At You

It was an awesome year here at EE Journal. Technology continued to evolve at a breakneck pace, and the EE Journal editorial team continued to drink beer. Oh, and (luckily, prior to those beers) we wrote down our thoughts and observations about what was going on in the world of electronic design. Apparently some of what we wrote was either interesting or inflammatory enough that bazillions of you found your way to the pages of EEJournal.com to read, comment, critique, disagree, or just stare in amazement at the pictures.
