Happy 40th birthday microprocessor

Happy 40th birthday microprocessor
by Paul McLellan on 11-16-2011 at 10:22 pm

Intel has been making a little bit of a PR fuss about the 40th anniversary of the microprocessor. And they are entitled to. The Intel 4004 was the first customer-programmable chip. Of course if you look at it’s capabilities today they are laughably minimal, and even looking at the chip, a 16-pin DIP (dual-in-line-package … Read More


Who is winning the cell-phone wars?

Who is winning the cell-phone wars?
by Paul McLellan on 11-15-2011 at 2:17 pm

Answer: it depends how you count. Units, market share, revenue, profit.

According to Gartner, Android has doubled its market share and now run just over half of the world’s smartphones. Android handset sales actually tripled during the year, selling 61 million last quarter, not that far off a million a day.

iPhone sales … Read More

I attended much of the Jasper users’ group a week ago. There were several interesting presentations that I can’t just blog about because companies are shy, and some that would only be of interest if you were a user of Jasper’s products on a daily basis.

But for me the most interesting presentations were several… Read More


Not your father’s Tensilica

Not your father’s Tensilica
by Paul McLellan on 11-14-2011 at 5:27 pm

Tensilica has been around for quite a long time. Their key technology is a system for generating a custom processor, the idea being to better match the requirement of the processor for performance, power and area as compared with a fully-general purpose control processor (such as one of the ARM processors). Of course generating… Read More


Old standards never die

Old standards never die
by Paul McLellan on 11-09-2011 at 4:14 pm

I just put up a blog about the EDA interoperability forum, much of which is focused on standards. Which reminded me just how long-lived some standards turn out to be.

Back in the late 1970s Calma shipped workstations (actually re-badged Data General minicomputers) with a graphic display. That was how layout was done. It’s… Read More

EDA Interoperability Forum
by Paul McLellan on 11-09-2011 at 3:06 pm

The 24th Interoperability Forum is coming up at the end of the month on November 30th to be held at the Synopsys compus in Mountain View. It lasts from 9am until lunch (and yes, Virginia, there is such a thing as a free lunch). I think it looks like a very interesting way to spend a morning.

Here are the speakers and what they are speaking… Read More


Using Processors in the SoC Dataplane

Using Processors in the SoC Dataplane
by Paul McLellan on 11-08-2011 at 9:17 am

Almost any chip of any complexity contains a control processor of some sort. These blocks are good at executing a wide range of algorithms but there are often two problems with them: the performance is inadequate for some application or the amount of power required is much too high. Control processors pay in limited performance … Read More


RTL Power Models

RTL Power Models
by Paul McLellan on 11-08-2011 at 8:00 am

One of the challenges of doing a design in the 28nm world is that everything depends on everything else. But some decisions need to be made early with imperfect information. But the better the information we have, the better those early decisions will be. One area of particular importance is selecting a package, designing a power… Read More


Think differentiation

Think differentiation
by Paul McLellan on 10-27-2011 at 5:01 pm

Wally Rhines’s keynote at the ARM TechCon was about differentiation and how to use it to create measurable value. We all know what differentiation means in some intuitive sense, but how do you make it measurable? Wally’s answer was that differentiation is a measure of the difficulty of switching suppliers and is best… Read More


Synopsys Journal, now on Itunes

Synopsys Journal, now on Itunes
by Paul McLellan on 10-24-2011 at 9:42 am

Synopsys Journal is a quarterly publication for management dedicated to covering the latest issues facing designers today. It has been published now for two and a half years. Of course, you can go here and, once registered, get a copy of the journal.

But people don’t have a lot of time to read a journal like this so it has been … Read More
