Computer Architecture and the Wall

Computer Architecture and the Wall
by Paul McLellan on 02-22-2012 at 1:08 pm

There is a new edition of Hennessy and Patterson’s book Computer Architecture: A Quantative Approach out. The 5th edition.

There is lots of fascinating stuff in it but what is especially interesting to those of us who are not actually computer architects, is the big picture stuff about what they choose to cover. Previous … Read More


Custom Processors: Webinar

Custom Processors: Webinar
by Paul McLellan on 02-21-2012 at 5:24 pm

What is a custom processor? Or Application Specific Instruction-set Processor (ASIP) which is the buzzword which may or may not catch on.

Most programming is done on a processor with a fixed instruction set: think Intel x86 or ARM. Intel or ARM decided on what instructions to include, based on a lot of benchmarking across a wide range… Read More


LTE-Advanced Handsets for 4G

LTE-Advanced Handsets for 4G
by Paul McLellan on 02-21-2012 at 7:00 am

Due to a lot of somewhat aggressive marketing by carriers, you might think that 4G wireless is already here. After all, wasn’t 3G ages ago? But in fact true 4G handsets won’t really be available until 2015/6. But to make that schedule, first silicon needs to be available late this year or early next, to allow one or two … Read More


Pinpoint: Getting Control of Design Data

Pinpoint: Getting Control of Design Data
by Paul McLellan on 02-20-2012 at 5:39 pm

Back in the Napoleonic era it was possible to manage a battle with very ad hoc methods. Sit on a horse on top of the highest hill and watch the battle unfold, send messengers out with instructions. By the First World War, never mind the second, that approach was hopelessly outdated and a much more structured way of managing a battle was… Read More


Power to the Drones

Power to the Drones
by Paul McLellan on 02-14-2012 at 6:01 pm

Unmanned systems are becoming indispensable to military forces and are used across all of land, sea and air. The generic name for such unmanned systems is UXS, usually UAS (air), UGS (ground) or UUS (underwater). The UAS is the most visible, both due to military strikes and the views of Japan after the Tsunami when areas were unreachable… Read More

Yes, there is such a thing as a free…model
by Paul McLellan on 02-09-2012 at 8:18 pm

I have been saying for years, ever since I started working at VaST, the biggest barrier to adoption of virtual platform technology for what I like to call virtualized software development is the availability of models. If models do not already exist when they are needed there are two issues: it takes money to develop them but, probably… Read More


DVCon: Hardware/software Co-design from a Software Perspective

DVCon: Hardware/software Co-design from a Software Perspective
by Paul McLellan on 02-09-2012 at 4:56 am

The EDAC Emerging Companies Comittee (would that be the EDACECC?) is organizing a free panel session one evening at DVCon. It is Monday February 27th from 6pm to 8.30pm. I don’t yet have a room but it will be at the DoubleTree Hotel where DVCon is being held.

EDA companies often address hardware/software co-design from a hardware… Read More


The Old Order Changeth

The Old Order Changeth
by Paul McLellan on 02-07-2012 at 3:02 pm

It is interesting watching as changes in technology bring giants to their knees. Far and away the best book on the subject is Clayton Christensen’s The Innovator’s Dilemma. If you haven’t read it then rush out and buy it immediately. In tech, you are not educated if you haven’t.

Two things made me think … Read More


FineSim Webinar

FineSim Webinar
by Paul McLellan on 02-07-2012 at 2:00 pm

FineSim is Magma’s circuit simulator that has been doing extraordinarily well. In my opinion it is one of the big reasons that Synopsys is acquiring (presumably, still subject to approval of course) Magma. FineSim is especially strong in the memory market with over 70% of the top 5 DRAM manufacturers and the top 10 flash manufacturers… Read More


Virtuoso has got you cornered

Virtuoso has got you cornered
by Paul McLellan on 02-07-2012 at 1:33 pm

Things you don’t know about Virtuoso: we’ve got you cornered.

That is the title on a Cadence blog item last week. It is actually about variability and how to create various corners for simulation and analysis, but given Cadence’s franchise for Virtuoso, its lock-in through SKILL-based PDKs and so forth, it … Read More
