Earlier this year, NVIDIA showed off a roadmap for its Tegra line of mobile system on a chip (SoC) processors. Namely, the next generation Tegra 4 mobile chip is codenamed Wayne and will be the successor to the Tegra 3.

Tegra 4 will use a 28nm manufacturing process and feature improvements to the CPU, GPU, and IO components. Thanks to a leaked slide that appeared on Chip Hell, we now have more details on Tegra 4.

The 28nm Tegra 4 SoC will keep the same 4+1 CPU design* as the Tegra 3, but it will use ARM Cortex A15 CPU cores instead of the Cortex A9 cores used in the current generation chips. NVIDIA is also improving the GPU portion, and Tegra 4 will reportedly feature a 72 core GPU based on a new architecture. Unfortunately, we do not have specifics on how that GPU is set up architecturally, but the leaked slide indicates that the GPU will be as much as 6x faster than NVIDIA’s own Tegra 3. It will allegedly be fast enough to power displays with resolutions from 1080p @ 120Hz to 4K (refresh rate unknown). Don’t expect to drive games at native 4K resolution, however it should run a tablet OS fine. Interestingly, NVIDIA has included hardware to hardware accelerate VP8 and H.264 video at up to 2560x1440 resolutions.

Additionally, Tegra 4 will feature support for dual channel DDR3L memory, USB 3.0 and hardware accelerated secuity options including HDCP, Secure Boot, and DRM which may make Tegra 4 an attractive option for Windows RT tablets.

The leaked slide has revealed several interesting details on Tegra 4, but it has also raised some questions on the nitty-gritty details. Also, there is no mention of the dual core variant of Tegra 4 – codenamed Grey – that is said to include an integrated Icera 4G LTE cellular modem. Here’s hoping more details surface at CES next month!

Ziilabs might not be a name you recognize now, but it is one you were likely familiar with at one time.  That is the current name of 3DLabs which was purchased by Creative back in 2002 and is now responsible for SoC development at Creative, especially integrating the StemCell media processor into the ARM chips which make the basis of the mobile processors.  Intel paid $30 million for physical resources and assets along with $20 million for patents, giving them the ability to move from their current solution for Atom processors, PowerVR to the StemCell architecture.  Could it be possible that with a stronger Atom that Intel might be able to power more cell phones and take a larger share of that market as well?  Check out more at The Inquirer.

"CHIPMAKER Intel will license patents from Ziilabs and purchase assets from the UK based chip designer.

Ziilabs is a UK based subsidiary of Creative Technology focusing on system on chip (SoC) designs for smartphones and tablets. While the firm has yet to register on the public conciousness, it clearly has been on Intel's radar for a while and announced a $50m asset sale and patent licensing deal."

ARM has made some serious impact on the mobile market with their Mali GPU on their SoC, with Jon Peddie Research reporting they have doubled their market share over the past year.  That number is even more impressive when you pair it with the 91.3% growth in the mobile GPU market.  Another player, Vivante, quadrupled their share of the market and while their products are found primarily in Asia you may recognize them as a member of the HSA.  Their success comes at a cost to Imagination and Qualcomm, both of whom have seen their market shares drop. NVIDIA is currently making up 2.5% of the GPU market for tablets and smartphones which is not too bad when you consider that the other four main players all license their processors out while NVIDIA remains the sole provider of its Tegra SoCs.  Get more numbers at The Inquirer.

Apple's A6 Processor Uses Hand Drawn ARM Cores to Boost Performance

Subject: General Tech, Processors, Mobile | September 27, 2012 - 12:26 PM |
Tagged: SoC, PowerVR, iphone, arm, apple, a6

Apple's latest smartphone was unveiled earlier this month, and just about every feature has been analyzed extensively by reviewers and expounded upon by Apple. However, the one aspect that remains a mystery is the ARM System on a Chip that is powering the iPhone 5. There has been a great deal of speculation, but the officially Apple is not talking. The company has stated that the new processor is two times faster than its predecessor, but beyond that it will be up to reviewers to figure out what makes it tick.

After the press conference PC Perspective's Josh Walrath researched what few hints there were on the new A6 processor, and determined that there was a good chance it was an ARM Cortex A15-based design. Since then some tidbits of information have come out that suggest otherwise, however. Developers for iOS disovered that the latest SDK suggest new functionality for the A6 processor, including some new instruction sets. That discovery tended credence to the A6 possibly being Cortex A15, but it did not prove that it wasn't. Following that, Anandtech posted an article that stated it was in a licensed Cortex A15 design. Rather, the A6 was a custom Apple-developed chip that would, ideally, give users the same level of performance without needing significantly more power – and without waiting for a Cortex A15 chip to be manufactured.

Finally, thanks to the work of the enthusiasts over at Chipworks, we have physical proof that, finally, reveals details about Apple's A6 SoC. By stripping away the outer protective layers, and placing the A6 die under a powerful microscope, they managed to get an 'up close and personal' look at the inside of the chip.

Despite the near-Jersey Shore (shudder) levels of drama between Apple and Samsung over the recent trade dress and patent infringement allegations, it seems that the two companies worked together to bring Apple's custom processor to market. The researchers determined that the A6 was based on Samsung's 32nm CMOS manufacturing process. It reads APL0589B01 on the inside, which suggests that it is of Apple's own design. Once the Chipworks team sliced open the processor further, they discovered proof that Apple really did craft a custom ARM processor.

In fact, Apple has created a chip with dual ARM CPU cores and three GPU cores (PowerVR). The CPU cores support the ARMv7s instruction set, and Apple has gone with a hand drawn design. Rather than employ computer libraries to automatically lay out the logic in the processor, Apple and the engineers acquired from its purchase of PA Semi have manually drawn out the processor by hand. This chip has likely been in the works for a couple of years now, and the 96.71mm^2 sized die will offer up some notable performance improvements.

It seems like Apple has opted to go for an expensive custom chip rather than opt for a licensed Cortex A15 design. That combined with the hand drawn layout should give Apple a processor with better performance than its past designs without requiring significantly more power.

At a time when mobile SoC giant Texas Instruments is giving up on ARM chips for tablets and smartphones, and hand drawn designs are becoming increasingly rare (even AMD has given up), I have to give Apple props for going with a custom processor laid out by hand. I'm interested to see what the company is able to do with it and where they will go from here. 

Chipworks and iFixIt also took a look at the LTE modem, Wi-Fi chip, audio amplifier, and other aspects of the iPhone 5's internals, and it is definitely worth a read for the impressive imagery alone.

GLOBALFOUNDRIES goes 3D with 14nm FinFET transistors

Subject: General Tech | September 21, 2012 - 01:58 PM |
Tagged: 14nm, FinFET, 3d transistors, GLOBALFOUNDRIES, SoC

Intel was first out of the gate with their 3D transistors, which they dubbed Tri-gate and which the rest of the world refers to as FinFET as the normal 2D transistor is flipped on its side in a position reminiscent of a fin.  This leads to much more efficient power usage, perfect for mobile designs and needed as the transistor density at 14nm is going to be quite high.  GLOFO's 14nm eXtreme Mobility will work in conjunction with the current 20nm process used to fabricate SOCs and will be the basis of many lines of chips, such as ARM who have signed a multiyear contract with GLOFO.  Check out DigiTimes for more.

"Globalfoundries has announced the launch of a new technology designed for the expanding mobile market. The new 14nm-XM offering will give customers the performance and power benefits of three-dimensional "FinFET" transistors with less risk and a faster time-to-market, helping the fabless ecosystem maintain its leadership in mobility while enabling a new generation of smart mobile devices, according to the foundry."

Kontron Readying Mini-ITX Form Factor ARM System

Subject: General Tech | July 14, 2012 - 02:39 PM |
Tagged: quad core, arm, SoC, Android, xbmc, htpc, mini-itx

This week has been rife with ARM computers. The latest ARM system comes in the form of a mini-ITX form factor motherboard and quad core ARM processor combination from embedded system manufacturer Kontron. Named the KTT30/mITX, it measures 17 cm x 17 cm, the little motherboard provides a plethora of IO ports and the relatively short (depth-wise) motherboard would be great in a HTPC box, assuming the software is there (an XBMC release ported over from the Raspberry Pi build would be nice to see, for example).

kontron.jpeg

The motherboard is paired with a quad core ARM Cortex A9 processor running at 900 MHz, video hardware acceleration coprocessor, and up to 2GB of DDR3L memory. It is reportedly capable of playing back 1080p H.264 videos. Internal connectors include two SD card clots, a SIM card socket, and two mPCIe connectors. Rear board IO includes three USB 2.0 ports (one micro, two regular-sized type A), an HDMI port, Gigabit Ethernet NIC, S/PDIF audio, two RS232 serial ports, and three analog audio output jacks.

It looks like a neat little board, though only if the price is right. If it is prohibitively expensive, it may be bumping up against AMD’s APU and accompanying motherboards. And because the APUs can utilize x86-64 software, that is a big positive in its favor. With that said, if this board is cheap enough, it could make sense as the base of a cheap HTPC.

Has Atom finally found its home ... in cell phones?

Subject: General Tech | June 21, 2012 - 01:43 PM |
Tagged: Medfield, SoC, atom z2460

Intel will be focusing a lot of attention on the mobile phone market this year, already they have started in Asia but hopefully it won't be too long until we start to see them here in North America.  Currently their Medfield SoC is fabbed on the 32nm process but we can expect to see 22nm chips with lower power consumption in the very new feature.  Companies unfamiliar to the West, such as Lava, Orange and ZTE are already either selling a phone or are about to release one, but those do not define the limits of the market.  DigiTimes describes their plans for the coming year as aggressive but with ARM already deeply entrenched in this market we have yet to see if this is the market where Atom will really find a successful niche.

"Intel's Medfield platform-based smartphones have recently received attention from handset players and telecom carriers such as Orange, Lenovo, Motorola Mobility, ZTE and India-based Lava International.

Lava International already launched its 4.03-inch Xolo X900, featuring Atom Z2460 processor (1.6GHz), 1GB memory, 16GB storage capacity, 8-megapixel camera and a battery that allows users to connect to the Internet through 3G for five hours and talk for eight hours. The smartphone is priced around US$400."

Samsung Teases Exynos 4 Quad Core Mobile Processor

Subject: General Tech | April 26, 2012 - 11:47 PM |
Tagged: SoC, Samsung, quad core, galaxy s 3, Exynos 4, Android

Samsung has an event scheduled for May 3rd called Mobile Unpacked where it will be unveiling their latest Galaxy series smartphone. It seems as if the company was too excited about the new hardware to wait because they have teased small bits of information on the processor. The new chip has been named the Exynos 4 and is a quad core processor running at 1.4 GHz.

img_4quad_1.png

Based on a 32nm HKMG (High-K Metal Gate) process node, Samsung claims the SoC uses 20% less power than it’s 45nm predecessors. The quad core processor is more power efficient thanks to the lower process node and the ability of the chip to turn individual cores off when not in use. As far as performance, the company claims the new quad core part is twice as fast as the older dual core 45nm chips. The Exynos 4 also has an integrated image signal processor for high quality camera processing and support for multi format codec (MFC) decoding. The MFC engine allows the chip to process a variety of 1080p HD video files.

A few things that are noticeably absent from the Samsung product page include any specific performance numbers, architecture details, and benchmarks. Samsung is keeping a tight lid on that information until the release but once reviewers get their hands on the Galaxy III independent benchmarks are soon to follow. The comparison between the Exynos 4 and NVIDIA’s Tegra 3 should be interesting.
