Developing ARM v8 Code…Today

Developing ARM v8 Code…Today
by Paul McLellan on 02-13-2013 at 12:50 pm

You are going to be developing software for an SoC that contains an ARM Cortex-A57 64-bit CPU. Or perhaps it is an SoC containing ARM’s hybrid big.LITTLE multi-core architecture that combines one or more low power cores with some high power, high performance cores to get the best of both worlds: high throughput when it is needed… Read More


ARMs in the Clouds

ARMs in the Clouds

The most interesting session at the Linley Tech Data Center Conference last week was the last one, on Designing Power Efficient Servers. What this was really about was whether ARM would have any success in the server market and what Intel’s response might be.

Datacenters are now very focused on power efficiency and many track… Read More


Software Driven Power Analysis

Software Driven Power Analysis
by Paul McLellan on 02-03-2013 at 8:15 pm

Power is a fundamentally hard problem. When you have finished the design, you have accurate power numbers but can’t do anything about them. At the RTL level you have some power information but it is often too late to make major architectural changes (add an offload audio-processor, for example). Early in the design, making… Read More


High Performance or Cycle Accuracy? You can have both

High Performance or Cycle Accuracy? You can have both
by Daniel Payne on 01-26-2013 at 10:55 pm

SoC designers have always wanted to simulate hardware and software together during new product development, so one practical question has been how to trade off performance versus accuracy when creating an early model of the hardware. The creative minds at Carbon Design Systems and ARM have combined to offer us some hope and relief… Read More


Battling SoCs: QCOM vs NVDA vs Samsung

Battling SoCs: QCOM vs NVDA vs Samsung
by Daniel Nenni on 01-13-2013 at 7:00 pm

If I had to describe CES in one word it would be exhausting. There were 3,000+ vendors, 150,000+ people, lines for everything, but 100% pure excitement. Even my beautiful wife was intrigued by the technology that shapes our lives. The smart toaster was of great interest to her since she says I time my toast with the smoke alarm. The … Read More

Formal Verification at ARM

Formal Verification at ARM
by Paul McLellan on 12-20-2012 at 4:34 pm

There are two primary microprocessor companies in the world these days: Intel and ARM. Of course there are many others but Intel is dominant on the PC desktop (including Macs) and ARM is dominant in mobile (including tablets).

One of the keynotes at last month’s Jasper User Group (JUG, not the greatest of acronyms) was by Bob… Read More

Here to make my stand, with a chipset in my hand
by Don Dingee on 11-16-2012 at 6:13 pm

Yesterday, I clicked “like” on a LinkedIn post with the title “TI Cuts 1,700 Jobs”. Today, I read the analysis and pulled out Social Distortion’s “Still Alive” for inspiration. I’ve been through this more than once. For them it’s not like-worthy, and I feel their sting.

The part of the post I liked was the comment: “This is good for … Read More


Carbon has Six Weeks of ARM, not to Mention Imagination and MIPS

Carbon has Six Weeks of ARM, not to Mention Imagination and MIPS
by Paul McLellan on 11-09-2012 at 12:18 pm

As George E.P. Box said, “essentially all models are wrong but some are useful.” That is certainly the case with Carbon’s models. For processors they have two models, one that is fast (but not timing-accurate) and one that is accurate (but not fast). But both are useful.

Carbon attended the ARM TechCon in Santa… Read More
