The CPU in the atrix is Dual-core ARM Cortex-A9 CPU, so why i see ARMV7?
it's beacuse that the andorid 2.2 not support in dual core?
The atrix will use the dual core just in 2.3 andorid ?
http://en.wikipedia.org/wiki/ARM_Cortex-A9_MPCore
Cortex-A9 uses ARMv7.
I'm not sure Android 2.2 uses dual core but apps that use dual core can still use both cores even on 2.2. (AFAIK)
wtf???
wtf?? the nvidea already develop the other processors?

thats ****ing nutz.....nvidea solt tegra 2 but of what I see they already have develop another processor ...nvidea don't realease the processor because they want do more money and a controled evolution......:S thats sucks...I want the last ARM power by tegra :'(
Every <THING> company that wants to survive is always working on the next-gen <THING> technology that is more advanced than their current <THING> technology.
Oh noes Toyota already has a new Prius for next year but wont sell it yet. And Apple already has a new MacBook but won't sell it yet. OMG coach has a new style bag and they are nit selling it yet.
Every company does this. Every company wants you to buy things now and then buy something else later. That is how companies make money.

It may be a typo in the build.prop but it says our processor is armv7 rev2.. Does anyone know if this is actually what's under the hood? I'd be pretty bummed
Pretty sure the processor is based on Arm Cortex A8 so it's last generation but dual core. The SGSII is based on Arm Cortex A9. Not sure how this relates to Armv7 though.

I was under the same impression but I'm still curious about the build.prop... idk probly just a screw up
From here:
CPU:
Architecture: ARM v7
ARM core: ARM Cortex-A9

Looks like there are 2 different ones. One for the chipset, one for the cores themselves. Chipset is ARM v7, Cores are A9
Also, I have no clue WTF any of this means. Google + 30 seconds = Some possibly useful info.
Edit: Okies, after doing some looking: There's no v8, only v7. The Cortex A9 is a subcategory of that, like different versions of it. Like we have gingerbread, 2.3. You can have subcategories of 2.3.3, 2.3.4, etc, which are all patches with improvements. So the CPU runs on ARM v7-A9, if that makes more sense...
Of course, this is how the processor is built, so it's not like it can be "Patched" to the newer versions when they come out... So that's just an example, to make it easier to understand.
The Scorpion CPU is a modified Cortex A8. ALL newer Cortex Ax CPUs are based on the ARMv7 instruction set architecture (ISA.)
Summary:
CPU is based on ARM's ARMv7 instruction set architecture intellectual property, which is branded Cortex A8. (Newer TI OMAP, and the Exynos are Cortex A9, basically unmodified, but are *still* using the ARMv7 ISA.)
Ergo, ARMv7 --> instruction set architecture, Cortex A8 --> configuration/branding.

Ah hah. Thankyou. Someone who knows what they're talking about, and isn't just pulling stuff out of their search engine.

Glad to help. I will be starting as junior faculty at the University of Louisville, and I'm teaching microprocessor design, so I hope I can remember all this! ARM definitely has made quite a salad of their branding. For instance, the classic ARM9 CPU is based on ARMv5, while the ARM7 is based on ARMv4 (if I'm not mistaken - I have a few of the dev boards lying around somewhere... there were actually variants of the 7 and the 9 that were both under v4 and v5 ISAs). The ARM11 (which was found in the newer 400MHz+ pocket PCs and smartphones of old) used the ARMv6 architecture, and all Cortex use ARMv7. What a mess! I guess that's what happens when you just create CPU core intellectual property, without manufacturing a single chip.

I've got an iPaq sitting here...I didn't even realize it was sitting here until you said ARM11 and then I looked down in back of my keyboard, saw that and a giant whooshing sounded flew through my head and reminded me that after reading all of your posts and thinking to myself "this guy really knows his stuff...wow, I doubt I could ever know all of that stuff" that, in fact, I already did in a previous life....lol.
But as you already stated (in different words) "Knowing" is the easy part, remembering is the hard part and to that end you have one upped me.
...wow, bizarre feeling, lol, thanks...
the scorpion core is not a modified a8 it is qualcomms own design that uses the armv7 instruction set

It is a modified ARM8 ISA CPU that uses the ARMv7 instruction set, Cortex is a branding.
...that is correct, and if it isn't swap a couple acronyms and numbers around and it will be.
if you r curious here are some links talking about how the scorpion core is similar and different from both a8 and a9

You are correct in that the Scorpion cannot be technically branded as an A8. Qualcomm licenses the ARMv7 ISA and basic core design (which ARM called Cortex A8) (when we implement these in FPGA, we call them softcores - kinda kinky. ). Qualcomm, when designing their initial Snapdragon, essentially gave a checklist to ARM for the reference design that they wanted their IP library to use.
For instance, Intel marketed the PXA 255 and PXA 270-series CPUs. (HTC PPC 6700 and Dell Axims, anyone? ). Despite being a CPU innovator in the desktop realm, the cores were still based on ARM reference designs - Intel's mobile division selected the reference they wanted, added MMX, etc., and then went to fab with it. By the same token, the Scorpion was based on ARMv7 ISA, which in its initial incarnation, as used by Qualcomm, was the Cortex A8. What came out of that is, logically, different, but related enough, the same way the PXAs were ARM11 reference desgins (ARMv6.) Qualcomm added the NEON instruction set, as well as out-of-order execution, for example, something the other Cortex CPUs didn't have (this may have changed with the A9), in order to increase data and instruction-level parallelism. They also added the ability to perform fine-grain CPU clock frequency and voltage throttling, much more so than in the stock A8 reference.
I guess in the long run, if they don't update their references to an A9 IP library variant, or perhaps something newer down the road, the Scorpion will start lagging behind the competition rather significantly. Not that I'm complaining at the moment, I love my 3vo's performance as it is.

here it says qualcomm does not use arms cortex reference designs but infact designed its own
if it is wrong than blame qualcomm... if I am misunderstanding it please explain

Boy, they certainly make it sound that way! My guess is that the truth lies somewhere in the middle. That they don't use the reference design is clear - the end-product isn't the same product that is the core design in the Cortex/v7 spec. However, I don't think that Qualcomm has the capital and the resources to do a full-scale, ground-up build of a CPU. Note that even Intel didn't do this (!) when they entered (and then promptly exited) the mobile CPU-building business.
The Qualcomm processor design team most-likely chooses attributes and then custom-designs additional features and configurations, and Qc does have the fabs to produce the silicon to state-of-the-art, or (state-of-the-art - 1) process technologies, as is clear from their stated transistor design (with a certain leakage factor) and feature size (45nm - keeping in mind that Samsung has this down to 32nm (you might want to check me on that, this may be a lie )).
So, let me restate my original opinion - I value your inputs, and this document certainly does its best to make the CPU look unique in the market. My understanding is that a certain core of the IP library is still present in the A8 format from ARM. It's entirely possible that none of the original architecture was kept in its native forms - design, routing, and layout might all be different, but I think ultimately, the CPU finds its roots in part of the original A8 design. To simply use the ISA without *any* reference to the original A8, I think, is beyond Qualcomm's capabilities, at least at present.
I suppose a reasonable example may be seen in the car world. Take the Lexus ES series vs. the Toyota Camry (just to name a plain-jane, basic example that most people would know.) The ES looks, performs, and runs differently. It has different features, a different pricetag, and many different interior and even engine-bay features (and probably a larger engine.) But ultimately, it is just an altered Camry. The extent of the alterations here is the question (and bringing an analog to an ISA into the automotive domain is tricky - maybe the use of an engine and 4 wheels? ). Anyway, perhaps only Qualcomm knows the answer, but well done sir, in bringing an in-depth discussion to the table.
To put this into layman's terms:
You can mostly think of the term "architecture" as being a language that the CPU speaks, and the software must therefore be written in that language (or as programmers refer to it, being compiled into that language.) Android apps speak java bytecode to the dalvik engine, which then translates and speaks ARMv7 to the CPU. Different phones can run on different architectures and still have the apps be compatible because the dalvik engine can be compiled for each different architecture.
Now, the "core" in this sense is the specific implementation of that architecture. The easiest analogy to that I can think of, is that intel and AMD CPU's both use the x86 architecture, but their implementations are way different. They are designed far different from one another, but in the end they speak the same language more or less.
There are variations to the ARM "language" which is indicated by the revision number (ARMv7) just as there are variations to the x86 "language." For example, you have x86 32-bit and you have x86 64-bit, and then there are extensions to x86 such as SSE, 3dnow, etc. It's a little more complicated than that, but that's the general idea.
Hi, i'm fairly new into this, but it got me interested, i've been reading about some "cheap high performance" processors, such as de renesas ev2 and the rk2918, with the ev2, some manofacturers do say that it is possible to use android honeycomb, the ev2 is a decent for the price dual core procesor, with a gpu that performs really close to the qualcomm mali that was on the first ipad (about 15m p/s) , the cpu is arm9. The rockchip does excel in 3d performance, its neon gpu is said to be able to get 60m p/s, while the processor itself is not bad, is A8 clocked at 1.2 ghz, single core. With this being told, i'm wondering if rk2918 devices will be able to run smoothly the soon to be released ics, or atleast the honeycomb (its source has not been released yet), or even though the ev2 has a worse gpu, is still a better pick? thanks in advance for your comments (except if they are insults)
Still wondering if processors suck as the rk2918 or the ev2 will be good enough to run a newer release of android, other than gingerbread, regards.
Hello, Good Day.!!
Hey guys i am little bit confuse about my Xperia mini Hardware
According to GSM ARENA The phone has
Chipset Qualcomm QSD8255 Snapdragon
CPU 1 GHz Scorpion
GPU Adreno 205
What does the CHIPSET stands for i mean what is the work of chipset? is it a Mainboard??
Some people said the phone has Snapdragon processor but here it says Scorpion.Snapdragon is a processor or a chipset??
http://wiki.answers.com/Q/What_is_t...the_functioning_of_processor_chip_and_chipset
http://en.wikipedia.org/wiki/Snapdragon_(system_on_chip)
Snapdragon is a chipset, Scorpion is a CPU. Every computer nowdays has both CPU and chipset, including smartphones. Also, in smaller/portable devices GPU can be embedded into chipset. IIRC Snapdragon is one chip that contains it all, CPU, GPU and Chipset.
Motherboard is a board that contain those chip(s)
The trends we are seeing in this part of the World (Asia) with the New Crop of "Value for Money" Smartphones is MediaTek Processors...
Be it Lenovo, Alcatel or all major vendors in Asia, China, Indonesia...they are starting to go with these Processors...
Having said that We see a lot of Bad Mouth about this brand of Proccy....so what the real deal?
All of us would agree when we are looking at a dual core smartphobe at under 200 $ prce bracket.....we cant expect a Snapdragon S3!
And looks like all new VFM Samrtphones from China OEM or other places who rebrand OEM are ending up being MediaTek!
Starting this thread to get some discussion going for more enlightenment....
Current MediaTek Proccys in Market :
- MT6575 : Single core Cortex-A9 solution with an unidentified 5-series PowerVR GPU
- MT6577 : Dual Core 1GHz Cortex™-A9 application processor from ARM, a PowerVR™ Series5 SGX GPU
MediaTek breaks into Top 5 in Smartphones Procy sales Worldwide!

bad mouth about mediatek, well i don't think so. mediatek processors should be at par with any other processors but the problem is afaik they dont release their kernel sources and they are still stuck with their sgx 531t gpu which is almost at par with our adreno 205 but not any better. however i might be wrong. i read about this a long time back and i dont remember the exact source.

I'd suggest to move the whole discussion to "Android General". There you will certainly find more people to discuss your particular issues and do not spam this board. Thank you....even if I sound like forum police now :laugh:
