A while ago we took a broad look at the status of IP, with an eye to ease of use, reuse, and interconnectability. And, in fact, it’s a complicated matter. Moreso when you get to the issue of interconnecting various kinds of IP. There are two fundamental challenges as our SoCs get more and more mind-bogglingly complex. One is how you hook all this stuff up, and the other is how you hook on to the hook-up.

There’s an ancient piece of marketing wisdom that says, “If you can’t fix it, feature it.” While commonly attributed to technology, it has, in fact, been practiced since pre-historic times.
When the Bosporus broke open, flooding the area now known as the Black Sea in an event that might be the Great Flood survived by Noah and his menagerie, it was presumably a catastrophe of immense proportions. Until some developers took a look at the new shoreline property on the Crimea and said, “Dude, these are some killer beaches!& … Read More → "Zero-Threading"
MILPITAS, CA – September 28, 2009 – Linear Technology Corporation announces the LT3980, a 2A, 58VIN step-down switching regulator with Burst Mode® operation to maintain quiescent current under 85µA. The LT3980 operates within a VIN range of 3.6V to 58V, with overvoltage lockout protection against transients as high as 80V, making the device ideal for load dump and cold-crank conditions commonly found in automotive applications. Its internal 3.4A switch can deliver up to 2A of continuous output current at voltages as low as 0.79V. The LT3980’s Burst Mode operation provides ultralow quiescent current, well suited for applications such as … Read More → "58VIN, 2A with IOUT, 2.4MHz Step-Down DC/DC Converter Draws Only 85µA of Quiescent Current & Withstands 80V Transients"

Enhanced DSP Capabilities
The success of the LatticeECP2M family in addressing the 2G/3G wireless arena, coupled with discussions with customers, has served to drive the architectural improvements made in the LatticeECP3 DSP block. Several key points have been addressed. First and foremost, backward compatibility has been maintained with the current LatticeECP2/M DSP. There is also finer control of … Read More → "Embedded Signal Processing Capabilities of the LatticeECP3 sysDSP Block"
Obsolescence is a familiar and friendly concept to engineers. In fact, it is our job. We are professional creators of obsolescence. Each day, we go to work with the goal of making some previous work of engineering obsolete. Our revised rodent retention device must surpass, supersede and exceed all previous versions, else we have failed.
Audio Cassettes – gone. Rotary-dial telephones – expurgated, and not a moment too soon. Typewriters, cathode ray tubes, mimeograph machines – all banished to the backwaters of vintage-retro curiosity by our hard-working, innovation-happy profession.

They were your typical pack of teenage kids. By turns rough-and-tumble and vulnerable. On top of the world while at the same time knocked about by forces they didn’t understand or couldn’t control. Watching them on the beach that Saturday, they could have been any kids anywhere in the world. They’d fight, they’d squabble, they’d play, they’d slap each other’s backs, they’d even undulge the slightest hint of a hug. They competed with each other and yet they were the best of … Read More → "A World Of Their Own"
In military parlance, an Osprey is a propeller-driven airplane that takes off and lands vertically, like a helicopter. The Osprey tilts its wings 90 degrees, the props pull it straight up, and the wings flip back again for conventional flight. Clever engineering, but a bit ungainly to look at.
Over in the less dangerous but equally contentious microprocessor world, ARM has also hatched its own Osprey, this one officially named the ARM Cortex-A9. The new A9 will be capable of 2-GHz clock rates, an unheard-of speed for an ARM core. The previous-generation A8 was barely able to … Read More → "ARM’s Race Escalates with Cortex-A9"
When the first semiconductors were created, they were the result of theoretical studies. As integration grew, so the device manufacturers and the equipment manufacturers pragmatically pushed ahead with brute force, scaling as they pushed down the Moore’s Law curve. Universities often struggled to keep abreast of developments, although, for a long way down the scaling curve, the mainstream underlying theories were pretty well understood.
Today we can no longer rely on scaling alone. Small channel effects, themselves difficult to understand and predict, are worked around by using double gates, raised sources and drains, surround gates, and … Read More → "Universities and Electronics"
