Nvidia Corp. on Monday introduced what it calls the world’s highest-performing application processors for tablets and smartphones. The new chip is among the first quad-core system-on-chip devices for mobile applications that packs ARM Cortex-A15 cores. The latest Tegra 4 also features a number of photography-related advantages.

Nvidia Tegra 4, previously code-named “Wayne”, features four ARM Cortex-A15 general-purpose cores as well as custom second-generation low-power general-purpose cores.  The chip also incorporates 72 custom Nvidia GeForce stream processors that provide six times graphics processing performance of previous-gen Tegra 3. The new application processor also fully supports output to ultra high-definition screens with up to 4K resolution (3840*2160). Tegra 4 offers exceptional graphics processing, with lightning-fast web browsing, stunning visuals and new camera capabilities through computational photography, according to Nvidia. The new SoC is made using 28nm process technology.

"Tegra 4 provides enormous processing power and efficiency to power smartphones and tablets, gaming devices, auto systems and PCs. Its new capabilities, particularly in the area of computational photography, will help improve a whole range of existing products and lead to the creation of exciting new ones," said Phil Carmack, senior vice president of the Tegra business at Nvidia.

Tegra 4 also enables worldwide 4G/LTE voice and data support through an optional chipset, the fifth-generation Nvidia Icera i500 processor. More efficient and 40% the size of conventional modems, i500 delivers four times the processing capability of its predecessor.

Among the Tegra 4 processor's advantages is its computational photography architecture, which automatically delivers high dynamic range (HDR) photos and video by fusing together the processing power of the GPU, CPU and the camera's image-signal processor. Its HDR capability captures images, including those taken with a flash, the way they are seen by the human eye – with detail in both bright and dark areas.

Designed for maximum energy efficiency, Tegra 4 includes a second-generation battery saver core for low power during standard use, and Prism 2 display technology to reduce backlight power while delivering superior visuals.

Tegra 4 consumes up to 45% less power than its predecessor, Tegra 3, in common use cases. And it enables up to 14 hours of HD video playback on phones.

Unfortunately, today Nvidia only formally introduced Tegra 4 and it is unclear when the first devices with the novelty inside are expected to become available.

I think this processor is very interesting.

[Ernest_at_the_Beach]

What is computational photography architecture?

[Democrat_media]

4 processors on a smart phone. But democrats say the private sector doesn’t work.

And meanwhile the government schools are still teaching with chalk I assume? LOL

Vizio's got a nice surprise at CES this year: one of the only tablets with a Tegra 4 processor inside you can find anywhere in the world, outside of some death vault at Nvidia headquarters. We used it.

The 10.1-inch slate—just a prototype for now—boasts an eye-pleasing 2560 x 1600 resolution, and was terrifically light given the horsepower inside. Unfortunately, there wasn't really much to do to stress all of that horsepower. The tablet was pretty naked, without any games, Internet connectivity, or very much in the way of processor-gulping apps to fire up. But all the apps I could find on the thing—Flipboard, the camera, Chrome—all exploded into view instantly. This thing will open apps very, very quickly. HDR camera snaps were, as promised, instantaneous, 1080p video playback was as smooth as it'd be on any full PC or laptop, and speeding through hi-res photos (the only stress test I could muster) didn't lag even slightly.

Without a big budget game to run on this thing, it's too early to be impressed, but the faint signs of awesomeness we can spot in the Tegra 4 in its infancy are exciting. The. Thing. Is. Fast.

Dunno, probably can’t afford any.

From PCMAG:

Nvidia's Tegra 4 Will Fix Your Cameraphone Photos

**************************EXCERPT****************************

LAS VEGAS—Don't you hate it when you take a picture outdoors and the blue sky turns white? Nvidia's new Tegra 4 processor for phones and tablets may be able to fix up your photos, as well as speeding up everything from Web page loads to games.

"Because our phone is now our most important camera, the ability to capture that magical moment comes and goes," Nvidia CEO Jen-Hsun Huang said here at CES. "In life, you only get one shot."

I’m guessing, and hoping, it’s doing more with imagers than just measuring light intensity per pixel - it’s doing calculations on that data to elicit even more imaging information. Remember news not long ago about a camera which took pictures that could be re-focused after the fact by the viewer? That’s just the start.

I keep envisioning adding a light sensor to each pixel on a display panel. Knowing the precise position of each, and operating fast enough, methinks one could grab intensity data and then, with some hardcore math & optical physics, take a large-frame photo - without a lens. Petty among other applications, we could finally have video conferencing where each person actually looks like they’re looking at the other and not annoyingly off-screen.

Do you know if any of these (pre-)processors are including dedicated Java,etc., interpreters,etc., and if that is assisting the speed?
