ARM Embedded in Motor Control demo

Posted by Charbax – March 4, 2011

ARM is showing Motor Control comparing two rotating water vessels, one controlled in a conventional manner, the other is controlled in a more advanced algorithm called Field Oriented Control on a STM32 Cortex-M3 processor. This more advanced algorithm allows more efficient operation of the motor, better control of the torque and allows for quieter operation. The idea is to use less power to control motors. This is just the start of their investigation into Field Oriented Control using the Cortex-M3 processor.

Reuters: ARM CEO Warren East talks about Windows on ARM

Posted by Charbax – February 22, 2011

At CES last month, Microsoft announced Windows for ARM, recently there has been rumors that Microsoft has over 1000 engineers working on it at full speed to get this released before the end of the year, here's an interview by Reteurs with ARM CEO Warren East at the Mobile World Congress:

ARM Dual-core Web browsing performance compared to Single-core

ARM is demonstrating Dual-core usage and how it increases web browsing speed at same power consumption.

ARM and IBM develop 32nm -> 28nm -> 22nm -> 20nm -> 14nm and smaller processors

Posted by Charbax – January 21, 2011

ARM and IBM have been collaborating for 3 years on designing smaller and smaller processors for the industry, improving SoC density, routability, manufacturability, power consumption and performance. Just a year ago, the standard was about 65nm for most ARM Cortex-A8 processors in devices on the market such as the Nexus One. About 6 months ago, 45nm ARM Cortex-A8 processors appeared on the market such as in the ipad/iphone4, galaxy tab/s, droid x/pro. Recent devices with Nvidia Tegra2 are 40nm. The next step for ARM Cortex-A9 dual-core and quad-core processors to appear on the market this year are in designs of 32nm (50% shrink off 45nm node) and 28nm (50% shrink off 40nm node). What's next? They are working on 22nm and 20nm designs for 2012 and have been announcing since ARM Techcon last November that they have 14nm designs for as soon as 2014 that are under work with IBM.

You have to consider, it's not possible to make them smaller than 0nm, there are no minus nanometers. Their achievements in shrinking processor designs are insane. The investments are huge. They have to invest billions of dollars in fundamental research of materials and processes, they have to invent new mathematical tricks. Some of these technologies take 10 years from the lab research to something that can be mass manufactured. To make it feasible, the ARM industry has to collaborate (2).

The reason for wanting smaller process size is to consume less power, to increase performance and to potentially lower cost of devices at the same time (factoring out the increasing cost of R&D for smaller designs through very huge scale).

Watch my video of IBM's Vice President of Semiconductor Research and Development, Dr. Gary Patton, keynoting on how they are getting to 14nm ARM Processor designs and smaller:

ARM is 20 years old today

Posted by Charbax – November 27, 2010

ARM was founded on November 27th 1990 in a converted barn outside Cambridge to exploit Acorn's single greatest asset, the intellectual property bound up in its home-grown Acorn - now Advanced - Risc Machine processors. 20 Billion ARM processors have been shipped these past 20 years. 100 Billion are expected for the next 10 years.

The initial investment was $275 Thousand from VLSI and $1.5 Million from Apple.

ARM's first task was to design a processor chip for the Apple Newton handheld, which for some reason commercially flopped. Could the reason have been its $800 price? Ironically, $800 is the same price consumers are paying for an unlocked iPhone today.

ARM's first profitable year was 1993. The Company's Silicon Valley and Tokyo offices were opened in 1994. The company now has offices and design centres across the world, including San Jose California, Austin Texas, Olympia Washington, Trondheim Norway, Sophia Antipolis Grenoble and Paris France, Grasbrunn Germany, Taipei Taiwan, Kfar Saba Israel, Seoul South Korea, Lund Sweden, Yokohama Japan, Shanghai Beijing and Shenzhen China, Bangalore India and Sentjernej Slovenia.

The founders of ARM consisted of 12 engineers led by Sir Robin Saxby who gave the company its global vision and the innovative licensing model under which it sold not physical silicon but designs for other companies to manufacture.

The introduction of the Nokia 6110 in 1998 was crucial to place ARM as the standard for powering mobile phones. Today, more than 5 billion people on this planet use mobile phones, 100% of which have an average of 2 and a half ARM Processors in them. (one as the main processor, one to control antennas and one for power management? etc). Smart phones have 4 or 5 ARM Processors inside them. (adding WiFi, touch screen controller?)

1998 was also the year ARM went public, it changed its name to ARM Holdings and freed itself of the differing agendas of its backers allowing it to present its products as a neutral platform for licensees who were competing among themselves. The years that followed and until now, demand for the ARM Architecture has exploded, and today chip providers ship more than 5 billion ARM Processors every year.

Now that ARM Cortex processors are proving themselves to be perfect for powering larger screens as in Tablets, it's only a matter of time, maybe weeks or months until multi-core ARM processors break into the Laptop, Desktop and Server markets.

The ARM Cortex-A9 Powered Chrome OS "NexusBooks" that could run 40 hours on a battery using a Pixel Qi screen, that could be sold below $199 within weeks or months from now, that product is the single biggest threat to Intel.

To ARM from, Happy Birthday! May the next year bring your designs of Dual-core ARM Cortex-A9 with Mali-400, then Tri-Core and Quad-Core, then ARM Cortex-A15 and Mali-T604 with help from the amazing software from Silicon Valley's Google, Apple, even Microsoft, create massive disruption of the old business models of the old PC/Desktop/Laptop/Server markets of the old Silicon Valley of Intel.

ARM Powered Google TV coming

Posted by Charbax – November 19, 2010

I already guessed it (2, 3, 4), logically, Google is working with ARM to prepare the ARM Powered Google TV boxes to come probably around early next year, by the same time Google TV OS is open sourced. This will allow for cheaper Google TV, probably down towards the $99 price point, depending on some versions of Google TV excluding the HDMI input and IR Blasters features. Here are my guesses for what good value ARM Powered Google TV should be sold at early next year:

Google TV on ARM Cortex-A9, full 1080p playback support, including high bitrates, high profile, h264 in MKV and other containers.

Output only version: $99

Input/Output + IR version: $149

"We are talking to Google, but we have nothing to announce right now," said Tudor Brown, president of ARM, at a technology conference in Taipei on Thursday.

Brown said ARM's latest processors are less expensive and require less power than Intel's Atom processor. "If Google TV is to be mainstream, it must be built on a lower power system, ...on lower cost technology," he said.

This way, all HDTV's shipping with ARM Cortex-A9 will be able to include the full Google TV features for just the additional cost of $25 or a bit more for making each HDTV Smart as Marvell's CEO Dr. Sehat Sutardja explained in his keynote from ARM Techcon.

ARM Mali-T604, the next generation GPU for ARM Powered devices

Posted by Charbax – November 13, 2010

Interview with Jem Davies and Ian Smythe on the ARM Mali-T604, the next generation graphics processor. Look forward to some insanely powerful graphics processors with the ARM Cortex-A15 processors that will start to be designed next year and available in consumer products the year after that.

ARM CoreLink 400 Series

Posted by Charbax – November 13, 2010

This is a Cache Coherent Computer subsystem. Allows to deliver a whole bunch of new use cases, two Quad Cortex-A15 clusters can be fully I/O coherent with the MAli-T604 graphics.
