AMD, which has become one of the first supporters of ARM architecture processors use in the server segment, releasing a Seattle family of products is now necessary to select the right words when talking about the obvious change of priorities .  A rare event with AMD representatives complete without mention of the fact that the demand on ARM-compatible solutions in the server segment is growing not as active as expected, and with limited material resources it makes sense to focus on the promotion of x86-compatible solutions . Barclays Technology Conference was not without mention of AMD's plans in promoting ARM architecture - at least for the reason that Qualcomm recently unveiled its first 10-nm processor for server applications. CFO Devinder Kumar immediately made it clear that the development of products with ARM architecture is not one area of activity for which the company is prepared to commit resources.  The ability to expand its presence in the segment of x86-compatible processors for server and game application currently has a higher priority for AMD. However, Mr. Kumar said that AMD has products with ARM architecture   - obviously referring to the server processors Seattle.  He also admitted that the third "certified" product, which will begin to fill the budget of AMD in the near future,  will be the product with the ARM architecture.  The first two, as we know,  gaming console Sony PlayStation 4 components Pro and Microsoft Project Scorpio - the latter will be released in the second half of next year.   By the way, the existence of such "exceptions to the rule," explained very simply.  For the development of AMD custom products paying customers, their own funds for this purpose it is not distracting.   Select Rating : Currently 10.00/10 1 2 3 4 5 6 7 8 9 10 46827 Rating: 10.0/10 (6 votes cast) Create products with ARM architecture is not a priority for AMD investments	Add Comment ( 1 ) CREATE PRODUCTS WITH ARM ARCHITECTURE IS NOT A PRIORITY FOR AMD INVESTMENTS

POSTER: computer news   ||   AMD ZEN SEV PROTECTION FOUND POTENTIAL VULNERABILITIES	DATE:2016-12-10
In October, AMD has officially published the data on the built-in processor architecture Zen protection of virtual machines.  Cloud services, as you might guess, are doing the work with remote services of a universal phenomenon and, therefore, become a stumbling block to malicious actions.  AMD has decided to go at the head of the data protection process at the processor level and its cache.  Thus, the server Zen version  will have built-in Secure data encryption blocks Memory Encryption (SME) and Secure Encrypted Virtualization (SEV).  Documentation explaining how to work blocks are already in the public domain. Interestingly, based on the available data, two German security specialist could be found in the work of the mechanism of AMD Secure Encrypted Virtualization three potential vulnerabilities.  a number of issues SEV technology recognized by them promising, but challenging.  Looking ahead, we note that AMD has commented on the accusations in the shortcomings that Zen-generation products on the market yet, so can not speak about the vulnerability.  S Before we talk about vulnerability, we recall that the SEV encrypts the data in the cache processor 128-bit AES-keys (with  key for each virtual machine).  The data is decrypted when loaded into the processor cache is encrypted and after unloading.  Encryption and decryption work for memories and for applications.  This allow to protect against attacks from a potentially vulnerable hypervisor. On paper it looks nice, but experts presented three scenarios, in which case the SEV protection may not work.  Firstly, in the case of SEV does not provide encryption command control blocks, gave itself the hypervisor, which will bypass the SEV.  Second, the values of the general-purpose registers in Zen is not encrypted, which leads to the potential leakage of critical data.  Third, the realized investment management method such as nested page tables allow vulnerable hypervisor to control the virtual machine and apply the so-called replay attack (memory replay attacks).  Once again I emphasize that all three scenarios exist only on paper, but what prevents implement them?

POSTER: computer news   ||    EUROPEANS PRESENTED A PROMISING FRAMEWORK FOR THE 5-NM TRANSISTORS	DATE:2016-12-10
In The conference IEEE International Electron Devices Meeting 2016 (IEDM) in San Francisco, the representatives of the European research center CEA-Leti (Grenoble, France) presented two interesting document: NSP: Physical Compact Model for Stacked-planar and Vertical Gate-All-Around MOSFETs and Vertically Stacked-Nanowires MOSFETs in a Replacement Metal Gate Process with Inner Spacer and SiGe Source / Drain .  The first document describes a theoretical model of  transistor with a stack structure and encompassing  gate, and the second is about the practical implementation of the 5-nm transistor stack structure with silicon nanowires and silicon-germanium gate (pictured below). In the first paper, researchers presented and proved the validity of methods of calculation of the surface potential inclusive gate (Gate-All-Around, GAA), taking into account many factors, including negative quantum effects, as well as taking into account the round, square and rectangular configurations gate FinFET transistors and conventional planar transistors .  The model also includes calculations of the transitional structures using nanowires and nanosheets (NanoWire / NanoSheet, NW / NS). For the proof of the model and the possibility to produce transistors with nanowires with the norms of 5 nm or less, researchers have created a stack of the transistor structure with built-in splitter.  Separator in practice shown to be effective in reducing spurious interference from adjacent gates.  Moreover, in practice the shutter implemented manufacturing technology of silicon and germanium.  This technology is sure developers can replace the current manufacturing process technology with transistors and metal gate insulator with high dielectric constant (HKMG).

POSTER: computer news   ||    ON MONDAY, XIAOMI WILL INTRODUCE AN ELECTRIC VEHICLE	DATE:2016-12-10
Chinese company Xiaomi  no stranger  experiment with different kinds of products - from light bulbs to air purifiers and televisions.  Now Xiaomi,  has become famous in the first place thanks to their smartphones, ready to enter the new market.  Next week it will introduce an electric vehicle. Xiaomi Company has published a teaser announcing the date of the next presentation.  It will be held on Monday, 12 of December.  On this day, Xiaomi will present its new product under the sub-brand MIJIA.  According to our colleagues, on December 12, we will see a new electric vehicle created by Xiaomi.  This can be either an electric bicycle or a motorcycle, and a full electric vehicle.   Xiaomi teaser hints at the fact that the new product will get cruise control, electronic anti-lock system E-ABS and perforated brake discs.  We can only wait for Monday to see what Xiaomi prepared for its customers .
