Atrevido 423 + V16 Vector Unit with its deeper RISC-V pipeline technology, Gazillion

Many modern processor performance benchmarks rely on as many as three levels of cache staying continuously fed. Yet, new data-intensive applications like multithreaded generative AI and 4K image processing often break conventional caching, leaving the expensive execution units behind them stalled. A while back, Semidynamics… Read More

Gazzillion misses 2

Modern CPU performance hinges on keeping a processor’s pipeline fed so it executes operations on every tick of the clock, typically using abundant multi-level caching. However, a crop of cache-busting applications is looming, like AI and high-performance computing (HPC) applications running on big data sets. SemidynamicsRead More

Floating-point computation has been a staple of mainframe, minicomputer, supercomputer, workstation, and PC platforms for decades. Almost all modern microprocessor IP supports the IEEE 754 floating-point standard. Embedded design, for reasons of power and area and thereby cost, often eschews floating-point hardware… Read More


Post-making new Things stand out on the IoT

Post-making new Things stand out on the IoT

Sales says this next IoT project is going to be huge. Engineering isn’t so sure. Marketing says we should pilot it to find out. If it were just software, it might not be such a problem, but with hardware comes investment tradeoffs. Without guaranteed volumes of millions of units, are ASICs a realistic option to hit aggressive size,… Read More

Walking into the Mentor Graphics booth at ARM TechCon, I was greeted by my friends Warren Kurisu and Shay Benchorin. It was good to see them both again. They were poised in front of a table with a Samsung tablet and a small Wi-Fi-ish box, next to a large Samsung printer. The demonstration was similar to a lobby check-in process, where… Read More


Nine Cost Considerations to Keep IP Relevant

Nine Cost Considerations to Keep IP Relevant
by Pawan Fangaria on 09-27-2015 at 12:00 pm

It’s about 15 years the concept of IP development and its usage took place. In the recent past the semiconductor industry witnessed start of a large number of IP companies across the globe. However, according to Gary Smith’s presentation before the start of 52[SUP]nd[/SUP] DAC, IP business is expected to remain stagnant for next… Read More

by Don Dingee on 08-27-2015 at 12:00 pm

If I grab 10 technologists and ask what are the most important issues surrounding the Internet of Things today, one of the popular answers will be “security.” If I then ask them what IoT security means, I probably get 10 different answers. Encryption. Transport protocols. Authentication. Keying. Firewalls. Secure boot. Over-the-air… Read More

When the news broke about the on, off, and on-again Intel-Altera merger a few weeks ago, I checked off another box on my Six Degrees of Kevin Bacon scorecard. That plus a $5 bill gets me a Happy Meal at McDonalds, but in a post-Altera world, it might be worth more.

On January 16, 2008, I’m sitting in a meeting with some Intel strategic marketing… Read More
