Nvidia: Power Efficiency of Kepler - Result of Close Collaboration with TSMC.


It is not a secret that performance, cost and power efficiency of chips depend on actual design as well as on process technology. A good chip design and advanced process technology almost always result in a proper product. But to make the best chip, its design has to be tailored for process technology and vice versa. Apparently, this is exactly what Nvidia and TSMC have done to make Kepler architecture exceptionally power-efficient.
"Today, the primary constraint on processor performance is the power consumption budget. So our goal is always to develop solutions that deliver the highest performance within a fixed power budget. Having a more efficient process enabled us to add more processing cores, thus increasing performance. Put simply, greater efficiency equals greater performance and optimal performance per watt," said Joe Greco, senior vice president of the advanced technology group at Nvidia.
Kepler was in many ways an ambitious project because it introduced a new architecture at the same time as a new silicon process technology node. To maximize the efficiency of Kepler architecture, which Nvidia needed not only to sustain leading positions on the market of computer graphics, but also to continue its progress on the market of high-performance computing, Nvidia had tochange our silicon process development model with TSMC.
Back in the days Nvidia and Taiwan Semiconductor Manufacturing Company worked independently:  TSMC prepared the process technology, Nvidia worked on the design. For Kepler, Nvidia began working with TSMC three years before our product tape-out (when the processor design is complete and ready for manufacturing). Working in tandem, the two companies created a production qualification vehicle (PQV) to allow the TSMC process engineers and Nvidia design engineers to optimize the process before the product tape-out. Through repeated prototyping, the companies were able to optimize both the process and design, creating a more efficient Kepler design rather than simply a chip in a standard 28nm process.

This is not the first time when TSMC collaborates with its major customers to tailor process technology for their needs and also not the first  time when chip designs are optimized for a process technology still in development. As chips get more complex and manufacturing technologies get thinner, even closer collaboration between chip designers and contract makers of semiconductors will be needed to create great products.
TSMC’s 28nm high performance (HP) process, the foundry’s most advanced 28nm process which uses high-K metal gate (HKMG) technology and SiGe (Silicon Germanium) straining. HKMG is a process that uses a gate insulator film with a high dielectric constant which reduces power by reducing gate leakage compared to the previous generation SiON gate. SiGe straining is a chemical process to stretch the silicon atoms to improve the mobility or the effective frequency of the transistor. Both technical advances improve the performance per watt of the transistor translating to a more power efficient system.

TSMC’s 28nm HP process, seen under an electron microscope, is 30% smaller than 40nm and about 35% more energy efficient.
"We are extremely proud of what we accomplished with Kepler. It combines Nvidia’s world-class GPU engineering with TSMC’s very best 28nm process. But while Kepler was a key milestone, it is one point in a continuum. We continue to improve on what we developed and continue our collaboration with TSMC. In fact, we recently received our first version of an enhanced PQV for 20nm from TSMC. That process will yield even greater efficiency for Nvidia’s next next-generation GPUs," said Mr. Greco.

Intel Aims to Rigorously Compete Against Nvidia, Qualcomm, TI, Others


After attempts to make it into mass smartphones that have lasted for ten years, Intel is finally inside several devices that are about to hit the market. While only time will tell whether the first breed of Intel Atom-based smartphones will be a success, Intel itself claims that it entered the market of mobile phones very seriously and for the win.
"Intel does not go into markets to be a small player. It is a billion-unit market, so there is a huge opportunity for us," said Stacy Smith, chief financial officer of Intel, in an interview with Bloomberg news-agency.
Starting from the Q2 2012 several companies, including Lava (which is already selling its devices), Orange and ZTE, in addition to Motorola Mobility and Lenovo, plan to release their x86 smartphones based on Intel Atom Z2460 platform in different parts of the world. The first three companies intend to use Intel's reference design and add their proprietary features to them in a bid to differentiate themselves from others, whereas Lenovo and Motorola/Google have their own developments based on Intel Atom system-on-chip with their own set of capabilities.
“As of a week ago, we had zero share. As of this week, it is zero-point-something, because the first phones are selling,” said Mr. Smith.
At present, Intel only sells application processors for smartphones, which means that its clients have to use third-party baseband processors to enable network connection. In the future, Intel will integrate its baseband capabilities into its system-on-chips for smartphones, which will not only allow it to target mainstream smartphones, but will put it directly against powerful ARM partners, such as Qualcomm, Texas Instruments and Nvidia (which is supposed to release its WWAN-enabled Tegra in early 2013). Will Intel's chips be competitive? Only time will tell.
Intel smartphone reference design is based on Atom Z2460 system-on-chip (Atom core at 1.60GHz, PowerVR-based graphics core with OpenGL ES 2.0, OpenGL 2.1, OpenVG 1.1 support clocked at 400MHz with hardware accelerated high-definition 1080p video playback, 32-bit LPDDR2 memory controller and so on) supporting HSPA+ with the Intel XMM 6260 communication processor. The reference design smartphones have 4.03" screens, 8MP cameras and use Google Android 4.0 operating system.

Apple is Ten Years Behind Microsoft with Security Technologies - Antivirus Developer.


As Apple Macintosh computers get more popular among end-users, more and more viruses and malware emerge for the platform, which has been known for its invulnerability, and more Mac personal computers get attacked. To make the matters worse, Eugene Kaspersky, the head of Kaspersky Lab, a leading PC security company, claims that Apple is significantly behind Microsoft when it comes to security.
"I think they are ten years behind Microsoft in terms of security. For many years I have been saying that from a security point of view there is no big difference between Mac and Windows. It has always been possible to develop Mac malware, but this one was a bit different. For example it was asking questions about being installed on the system and, using vulnerabilities, it was able to get to the user mode without any alarms," said Eugene Kaspersky, chief executive officer of Kaspersky Lab, in an interview with CBR web-site.
It has always been a matter of time before mass malware for Apple Macintosh platform would emerge. Recent record sales of Macs have just catalyzed designers of viruses to develop  malicious software for Apple computers. The problem is that Microsoft is ready to fight the problems all the time and release appropriate patches within hours after a problem transpires. Apple could not react instantly on the recent Flashback and Flashfake outbreaks.
"Apple is now entering the same world as Microsoft has been in for more than 10 years: updates, security patches and so on. We now expect to see more and more because cyber criminals learn from success and this was the first successful one," said Mr. Kaspersky.
Essentially, Apple will have to do what Microsoft did ten years ago. It will have to reconsider update policy, create rapid-response security teams and invest more into security of its Mac OS in general.
"They will understand very soon that they have the same problems Microsoft had ten or 12 years ago. They will have to make changes in terms of the cycle of updates and so on and will be forced to invest more into their security audits for the software. That is what Microsoft did in the past after so many incidents like Blaster and the more complicated worms that infected millions of computers in a short time. They had to do a lot of work to check the code to find mistakes and vulnerabilities. Now it's time for Apple [to do that]," concluded one of the world's top security experts.

Western Digital Confirms Development of Hybrid Hard Drives.


Western Digital on Thursday confirmed that it had started development of hybrid hard drive (HHD), which combines rotating magnetic media and NAND flash in a single storage solution. With the acquisition of Hitachi GST and its expertise with solid-state drives, it is likely that the HHD initiative at WD will speed up.
"We are continuing investments in strategic growth areas such as SSD, hybrid drives and the digital home," said John Coyne, chief executive officer of WD, during quarterly conference call with financial analysts.
Last year Western Digital said that it started to evaluate feasibility of hybrid drives as solid-state drives did not, in WD's opinion, provide the right value proposition for the client PC market. The destiny of the hybrid drive initiative at Western Digital has so far been unclear.
Apart from Samsung Electronics and Toshiba Corp., which are the world's largest makers of flash memory, neither of leading-edge makers of hard disk drives - Hitachi, Seagate and Western Digital - have unveiled broad lineups of solid-state drives for consumers. By contrast, various suppliers of branded memory modules have already launched large families of own-brand SSDs. Moreover, OCZ Technology, formerly known for memory modules, even managed to become a leading manufacturer of both client, server and enterprise solid-state storage solutions, posing a threat to hard disk drives.
So far, only Seagate Technology has released Momentus XT hybrid hard drive with 8GB of single-level cell (SLC) NAND flash memory and 750GB rotating media. Momentus XT uses Adaptive Memory technology to identify data usage patterns, and then move the most frequently retrieved information to solid state memory for faster access. Adaptive Memory effectively tailors hard drive performance to each user and the applications they use.
No details about forthcoming hybrid hard drive from Western Digital are available today.

AMD, Globalfoundries, Others Set to Use Fully-Depleted SOI with 14nm, 20nm Chips.

Soitec, a leading designer of materials for semiconductors, has announced its fully depleted (FD) product roadmap comprising two products designed for both planar and three-dimensional (FinFET) approaches to building transistors. Industry checks by X-bit show that AMD, Globalfoundries and some other companies are interested in FDSOI for 20nm chips.

"Our fully depleted product roadmap addresses the critical needs of the semiconductor industry and solves key challenges facing manufacturers today. Whichever path chip vendors choose to follow – planar or FinFET – Soitec provides solutions that address cost, performance, power-efficiency and time-to-market issues. FD-2D enables immediate and significant performance leaps, while FD-3D makes FinFET a reality for the entire industry at accelerated schedules and reduced risk," said Paul Boudre, chief operating officer of Soitec.

Based on industry checks, X-bit labs believes that Globalfoundries and other partners will use fully-depleted SOI with its 20nm processes and more advanced technologies for making chips, including those designed by Advanced Micro Devices.



Fully-depleted wafers from Soitec, pre-integrate critical characteristics of the transistor within the wafer structure itself. Soitec’s FD wafers offer an early, low-risk migration at the 28nm node down to 10nm and beyond, lowering costs and enabling significant advances in the performance and power efficiency of mobile devices such as smartphones and tablets.

Soitec’s FD-2D product line enables a unique planar approach to fully depleted silicon technology as early as the 28nm node, in which chipmakers can continue to leverage their existing designs and process technologies. FD-2D also enables immediate gains in performance and energy efficiency for mobile and consumer multimedia chips.

The company’s FD-3D product line facilitates the introduction of three-dimensional (FinFET) architectures with reduced time and investment, and drives substantial simplifications in the transistor fabrication process, targeting nodes below 20nm.

Soitec’s proprietary Smart Cut layer transfer technology is said to generate thin layers with high quality and uniformity, bringing the ability to tune starting wafers to successive technology nodes and delivering key advantages as chip manufacturers pursue the best performance, efficiency and manufacturability results.

Microsoft to Redesign Iconic Windows Logotype: Rumours

Microsoft Corp.'s next-generation Windows 8 operating system will not only bring support for ARM-based microprocessors and a new user interface, but will also reportedly change the iconic logotype of Windows itself. The new Windows logo will allegedly get two-dimensional "Metro" style and will look like a set of single-color tiles.



CnBeta web-site has managed to obtain a series of screenshots that depict alleged new Windows logotype stylized for Microsoft Corp.'s new Metro style, which is a key part of Windows Phone and Windows 8 for tablets operating systems. TheVerge web-site has been able to verify the authenticity of the new design and confirmed that the new logotype will replace the legendary flag logotype of Windows.


Evolution of Windows logo: from Windows 1 to Windows 3 to Windows XP to Windows Vista to Windows 8

The alteration of the Windows logo will once again mark transformation of Windows as an operating system and a fundamental change of Microsoft's focus. What is unclear is whether the new logo in particular and Metro style in general will truly be as attractive as traditional interfaces for Windows users.
