Samsung claims 60 percent of dual-core processor market in 2011

News by Michael Oryl on Wednesday May 02, 2012. 0 Comments

Research firm Strategy Analytics has released a report that claims that dual-core processors made up 20 percent of all mobile processors shipped in calendar year 2011. Samsung( INFO) accounted for a 60 percent share of the dual-core processor market based on volume, followed by Qualcomm( INFO) (with 16 percent), Texas Instruments, and NVIDIA.

According to the report, Samsung's leading performance was due to its chips being found in both the Apple iPhone and iPad as well as its own successful line of Android powered smartphones and tablets.

The report says that the majority of single-core processors shipped in 2011 were part of an integrated "system-on-chip" chipset, while only 10 percent of dual-core processors in 2011 were similarly integrated. That 10 percent figure is likely to grow this year, as manufacturers have had more time to build more complete dual-core chipsets.

Strategy Analytics expects dual-core processors to continue to grow in 2012 and 2013 in spite of the appearance of the first quad-core processors, such as the NVIDIA Tegra 3 and the upcoming S4 Pro versions of Qualcomm's Snapdragon line. In particular, SA believes that the new low-cost ARM Cortex-A5 based CPUs will help with dual-core market penetration starting in early 2013.

Xamarin ports Android from Java to C#

The code could be used to build Android phones that don't rely on Java

MAY 03, 2012
By Mikael Ricknäs | IDG News Service

Xamarin has ported Android to C# in an effort to improve its own development tools and show that the OS doesn't have to be dependent on Java.

Development tools vendor Xamarin was started in May last year to take care of the Mono project, an open source implementation of the .Net framework, after Attachmate decided to drop it following its deal with Novell, where Mono had its home previously.

Today, Xamarin offers cross-platform development tools for iOS and Android.

When working on how to improve the performance of its tool for Android, the company hit a wall because of performance issues with Dalvik, which is Android's virtual machine, it wrote in a blog post on Tuesday.

One idea the Xamarin team had was to translate Android's source code to C#. A few months later skunkworks project XobotOS was born.

The result of the project's efforts is that most of Android's layouts and controls have been ported to C#, and the code is available on GitHub, according to the blog post.

"Turning XobotOS into something that can run on phones can be done ... Someone like Google or Amazon could do it and get 10 years of performance optimization,"
said Miguel de Icaza, CTO at Xamarin.

As big proponent of C#, de Icaza thinks Google was a little premature when it decided to go with Java for Android. Google is now embroiled in a court battle with Java owner Oracle over whether it violated patents and copyrights in its use of Java.

"I think that C# gets overlooked because it came from Microsoft originally. But today it is an ISO standard," said de Icaza. He contrasts that history with Java's, which Sun submitted for standardization but then withdrew.

Microsoft has also included C# in its Community Promise, which states that the company "irrevocably promises not to assert any" claims against it.

In the end, Xamarin wants to concentrate on improving its development tools, and so XobotOS will not be a focus going forward, the company said.

However, a few technologies that have come out of the effort will be included in future versions of its products.

For example, today, Mono for Android accesses the underlying graphics libraries via Java, but with the code Xamarin built for XobotOS it can skip that step and get straight to the native rendering code in Android's graphics engine.

"Graphics applications will run faster with Mono and C# than they do with Dalvik and Java," said de Icaza.

Xamarin now has the tools necessary to replace some chunks of Java code with C# code where performance is critical and when C# can offer an improvement, as well.

The translation was made easier using a tool called Sharpen, which was originally created by db4object. Xamarin improved the tool, making it more scalable and updating it to work with modern Java idioms, while doing the actual translation work, according to de Icaza.

"Sharpen has a lot of benefits, not only for us but for other people, so we open sourced all of our code. We are hoping it will be useful for other people that are looking at doing Java to C# translations for whatever needs they might have," said de Icaza.

Along with XobotOS, the new version of Sharpen was also published on GitHub.

I would give anything if they ported VB along with C# to Mono. Seems so stupid to me that they havn't.

The syntaxes for Java and C# are very similar. The first time I saw C# it was very understandable code, because it looked so much like Java...

Theres are several online web apps that allow one to easily translate C# code to VB and visa versa; but I've a strong personal preference for VB.

Anyhow, all of those .Net languages are incredibly easily to work with. Semaphores, critical sections, asynchronous multithreaded stream reading/writing, thread safe calls... theres a lot of easy-to-follow examples out there that make the tough stuff seem rather easy. I'm trying to improve my skills in storyboard animation (targeproperty binding, keyframes, easings) thats expected in good modern apps now. and on the back end, WCF really rocks.

Samsung Galaxy S III Performance Preview: It's Fast
by Brian Klug & Anand Lal Shimpi on 5/3/2012 6:13:00 PM

Browser & CPU Performance: Very GoodAs always, we start with our Javascript performance tests that measure a combination of the hardware's performance in addition to the software on the device itself. Sunspider performance is extremely good:

While we thought we hit a performance wall around 1800ms, the One X from HTC, the Lava XOLO and now the Samsung Galaxy S III have reset the barrier for us. In this case the performance boost is likely more due to software than hardware, but the combination of the two results in performance that's better than almost anything we've seen thus far. The obvious exception being Intel's Medfield in the X900.

BrowserMark is another solid js benchmark, but here we're really able to see just how much tuning Samsung has done in its browser:

The Galaxy S III is significantly faster than anything else we've ever tested thus far. The browsing experience in general is very good on the SGS3, and the advantage here likely has more to do with Samsung's browser code and the fact that it's running Android 4.0.4 rather than any inherent SoC advantage. We know how 1.4GHz Cortex A9s should perform, and this is clearly much better than that.

Once again we turn to Qualcomm's Vellamo to get an idea for browser and UI scrolling performance:

Although (understandably) not as quick as the Snapdragon S4 based One X, the SGS3 does extremely well here - likely due in no small part to whatever browser optimizations ship in Samsung's 4.0.4 build. As Brian put it when he first got time with the device: it's butter.

GPU Performance: Insanely FastWhile we don't know the clocks of the Mali-400/MP4 GPU in the SGS3, it's obviously significantly quicker than its predecessor. Similar to what we saw when the Galaxy S II launched, Samsung once again takes the crown for fastest smartphone GPU in our performance tests.

The onscreen GLBenchmark Egypt and Pro results are understandably v-sync limited, but if you look at how much headroom is available thanks to the faster GPU it's clear that the Galaxy S III should be able to handle newer, more complex games, better than its predecessor.

What's particularly insane is that Samsung is able to deliver better performance than the iPhone 4S, the previous king-of-the-GPU-hill in these tests.

The performance advantage isn't anywhere near as staggering if we look as BaseMark ES 2.0, however as we've mentioned before this benchmark is definitely showing its age at this point. Despite the aggressive tuning Qualcomm has done for these benchmarks, Samsung is actually able to remain competitive and even pull out a slight win in the Taiji test. Both benchmarks are v-sync limited on the fastest platforms however.

Final WordsOur first interactions with Samsung's Exynos 4 Quad are promising, but there's still much more to understand. Samsung clearly used 32nm as a means to higher GPU clock speeds, which in turn gives us much better GPU performance. The big unknown, as always, is power consumption. Based on what we've seen thus far from Samsung's 32nm LP process in Apple's iPad 2,4 (review forthcoming), Exynos 4 Quad should be a pretty good step forward in the power department as well.

As soon as we can get our hands on final hardware you can expect a full review of the Galaxy S III, including power and battery life analysis.

Initial reactions to the Galaxy S III announcement seemed almost disappointing, however stay tuned for our hands on impressions of the device as well as even more depth/detail on the hardware platform - you may be surprised.

End of the road for bada: Perhaps encouraged by its success with Android, Samsung is reportedly abandoning its own OS, bada. According to Editor and rumor-monger Eldar Murtazin, Samsung is wrapping up work on the platform and plans to stop supporting it by the first half of next year. Developers that were working on the OS will migrate to Android, Murtazin suggests.;

Apple's iPad 2,4 also uses 32nm A5 S5L8942 SoC
by Brian Klug on 4/11/2012 2:27:00 PM

Through Chipworks, we recently learned that Apple's revised A5 SoC (S5L8942) is built on a 32nm Samsung HKMG process. While its presence in the Apple TV (3rd generation) which we've reviewed and inspected is an absolute certainty, up until recently it hasn't been as common knowledge that the iPad 2,4 ($399 cost reduced Wi-Fi model) also contains the same S5L8942 SoC but with both A9 cores enabled, as opposed to the single core A9 configuration of the Apple TV 3.

Ericsson downloaded a welter of statistics during its Annual General Meeting held Thursday in Stockholm. The Swedish giant said it spent about 33 billion Swedish kronor (US$4.87 billion) on R&D in 2011 (about 14.5 percent of its full year revenues) and that it has about 22,000 staff engaged in R&D activities. The vendor also repeated its claim to have grabbed a 38 percent share of the global mobile network systems market last year, up from a 32 percent share in 2010. Ericsson now believes it is twice as large as its nearest mobile infrastructure rival, which would be Huawei Technologies Co. Ltd. (See Ericsson Suffers Margin Crunch.)

NSN has amended its divestiture deal with DragonWave Inc. (AIM/Toronto: DWI; Nasdaq: DRWI), which is buying most of the vendor giant's wireless backhaul business. Under the new terms, the two companies have agreed on a set of services and development relationships under which NSN will, for now, retain its backhaul assets in Italy. The asset sale was first announced in November 2011 and has become part of NSN's restructuring program. (See DragonWave Amends NSN Deal, DragonWave to Buy NSN Unit, NSN Could Lose More Than 17,000 Staff and NSN Unveils Its Kill List .)

Separately, NSN will show off what it says will be a world record Long Term Evolution Time Division Duplex (LTE TDD) data connection speed of 1 Gbit/s at the CTIA Wireless 2012 show in New Orleans next week, where it will also unveil a number of new LTE TDD products.
