To NVIDIA Tegra 2 or why smartphone two kernels

From this article you can learn about the first smartphone on the basis of new system-on-a-chip from the NVIDIA company. In other words, it is a question of a dual-core processor in the ordinary smartphone or the mobile phone.
Let's understand a little that such for system on the Tegra 2 chip and what devices on it will appear soon.
NVIDIA Tegra 2 technology
The system on the chip (crystal) - in microelectronics is the electronic scheme carrying out functions of the whole device, for example, of the computer and placed on one integrated scheme. Simply speaking, the system on the chip is a high-grade microcomputer which can be used in the most different equipment, from mobile phones to TVs.
The physical size of the chip doesn't exceed a standard American coin in 25 cents that allows to use it in the most tiny devices.
Advantages of system on a crystal are obvious to the producer – he receives ready chips from the developer and integrates them into the production.
As a result it is not necessary to be engaged in creation of drivers, hardware "binding" for the processor etc. It is enough to take care of input-output devices. The cycle preceding a product yield on the market, decreases, - all in a prize. Thanks to the concept «system on the chip» announcements of new decisions on the basis of NVIDIA Tegra 2 appear almost each day.
Let's look that this system on the chip represents.
NVIDIA Tegra 2 unites in itself two computing kernels of Cortex A9, graphic and audio processors, and also the allocated coprocessors for video coding/decoding, controlers HDMI, USB, NAND and the screen. Generally, everything that is necessary for work, it was necessary to connect only the display, the periphery and the battery.
As we see, in SoC stuffing (or system on chip - system on the chip) is provided by system-on-a-chip a separate element for each more or less resursoyemky operation that should provide the solution of complex challenges which not on forces of CPU, and also to divide their streams between different hardware. Also the system on the chip spends an accumulator charge much more economically. After all it is not obligatory to load the central processor as, for example, when coding video, now it can do it in a force floor on full capacity.
But the most important, products on the basis of this System on Chip receive essentially new possibilities first of all connected with graphics. Founders of games can use more difficult cursors for 3D-pictures.
The second, not less hot problem which plainly didn't manage to be solved, - Flash. For producers of Android-devices this technology - one of few arguments against the leader of the market of tablets and the serious smartfonny player - Apple. But it is not enough to make Flash support programmno in system, the resources demanded for this purpose while were inaccessible to these types of devices. Formally it is in Samsung Galaxy Tab by means of which it is possible to watch, for example, video not at YouTube or Vimeo.
But here to pass usual Flash-game or is high-grade to load the website which has been completely constructed on Flash, already hardly. Simply there are no hardware resources. Well and, certainly, shooting and reproduction of Full of HD video. Though about, whether really it is necessary function or marketing dodge, the journalist and the representative of the company can argue to blue in the face.
All this products on the basis of NVIDIA Tegra 2 theoretically should be able.
Let's look on those from them which emergence in the market is expected soon.
Devices on the basis of NVIDIA Tegra 2
The main problem of decisions on the basis of System on Chip NVIDIA Tegra 2 - them still isn't present on sale. Though some tens which big share tablets as from known producers (make Motorola, LG, Dell), and sets of the companies, whose names about anything don't speak to the ordinary buyer are announced already.
On Mobile World Congress, passing from the stand to the stand, it was possible to test an easy deja vu. The same tablets, on the same Android 3.0 Honeycomb. One differ outwardly, others are similar as twin brothers. Also it is a big problem as for producers as they still have less space for maneuver, and consumers who can't understand plainly in what the difference between new devices and whether is available that in general.
Therefore to a course there are 3D-chambers, design and all the rest that doesn't concern directly direct mission of a product. The one will win who can begin earlier deliveries, develop more attractive design, and the most important to appoint acceptable cost.
Closest to real sales while LG Optimus Pad and Motorola Xoom. And here in price policy Motorola which promises to sell the younger Xoom Wi-fi version for $599, but while only in the USA is in the lead. We in the country the first will have a representative of a smartfonny ruler - LG Optimus 2x P990 (reproduces video with permission 1080p).
Device merits and demerits on the basis of NVIDIA Tegra 2
Experts tested NVIDIA Tegra 2 possibilities for LG Optimus 2x P990. Let's look that turned out.
Speed of the real device really appeared at height. Both in tests, and in usual work of Optimus 2x proved the good fellow. It actually is capable to "digest" HD video Full, and both to reproduce, and to write down. And games which support its possibilities, look absolutely in a different way, than on one-nuclear colleagues. Also you can look through absolutely quietly practically any Flash-video, and here with the sites created on the basis of this technology, problems nevertheless aren't excluded. No less than it is not necessary to hope that you will manage to play in any of numerous games which on the Internet more than it is enough. To be started that they can, and will be started, but here any of the tested projects isn't calculated on touch management.
Now about real shortcomings.
The most afflicting - autonomy improvements so it was not felt. Certainly, to do conclusions on the basis of the only thing and that not a final sample early. But, nevertheless, it is possible to argue that LG Optimus 2x is no more hardy, than his one-nuclear colleagues. About any gain of autonomy of speech isn't present in principle. And it, undoubtedly, main minus. Any productivity, Flash and HD videos won't be necessary to you, if phone completely is discharged in the middle of the working day.
As a result
At the same time for 2011 of Tegra 2 is a top decision, to wait which in models of an average price segment it is impossible. It will appear in Russia only in 2012, together with Tegra 3 exit, that is with the advent of chips of new generation.
In any case, Tegra 2 use in a number of models including in LG Optimus 2x, allows to achieve speed of operation of the interface, a number of appendices and functions which was unattainable in the previous leaders of any company. It is a new performance level.
