Cortex-A17
The ARM Cortex-A17 is a 32-bit processor core implementing the ARMv7-A architecture, licensed by ARM Holdings. Providing up to four cache-coherent cores, it serves as the successor to the Cortex-A9 and replaces the previous ARM Cortex-A12 specifications. ARM claims that the Cortex-A17 core provides 60% higher performance than the Cortex-A9 core, while reducing the power consumption by 20% under the same workload. ARM renamed Cortex-A12 to a variant of Cortex-A17 since the second revision of the A12 core in early 2014, because these two were indistinguishable in performance and all features available in the A17 were used as upgrades in the A12. New features of the Cortex-A17 specification, not found in the Cortex-A9 specification, are all improvements from the third-generation ARM Cortex-A, which also includes the Cortex-A7 and Cortex-A15: * Hardware virtualization and 40-bit Large Physical Address Extensions (LPAE) addressing * Full-system coherency, bringing support for ...

ARM Cortex-A12
The ARM Cortex-A12 is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture. It provides up to 4 cache-coherent cores. The Cortex-A12 is a successor to the Cortex-A9. ARM renamed A12 as a variant of Cortex-A17 since the second revision of the core in early 2014, because they were indistinguishable in performance. Overview ARM claims that the Cortex-A12 core is 40 percent more powerful than the Cortex-A9 core. New features not found in the Cortex-A9 include hardware virtualization and 40-bit Large Physical Address Extensions (LPAE) addressing. It was announced as supporting big.LITTLE, however shortly afterwards the ARM Cortex-A17 was announced as the upgraded version with that capability. Key features of the Cortex-A12 core are: * Out-of-order speculative issue superscalar execution pipeline giving 3.00 DMIPS/MHz/core. * NEON SIMD instruction set extension. * High performance VFPv4 floating point unit. * Thumb-2 instruction set enc ...

List Of ARM Cores
This is a list of central processing units based on the ARM family of instruction sets designed by ARM Ltd. and third parties, sorted by version of the ARM instruction set, release and name. In 2005, ARM provided a summary of the numerous vendors who implement ARM cores in their design. Keil also provides a somewhat newer summary of vendors of ARM based processors. ARM further provides a chart displaying an overview of the ARM processor lineup with performance and functionality versus capabilities for the more recent ARM core families. Processors Designed by ARM Designed by third parties These cores implement the ARM instruction set, and were developed independently by companies with an architectural license from ARM.

ARM Holdings
Arm is a British semiconductor and software design company based in Cambridge, England. Its primary business is in the design of ARM processors (CPUs). It also designs other chips, provides software development tools under the DS-5, RealView and Keil brands, and provides systems and platforms, system-on-a-chip (SoC) infrastructure and software. As a "holding" company, it also holds shares of other companies. Since 2016, it has been owned by Japanese conglomerate SoftBank Group. While ARM CPUs first appeared in the Acorn Archimedes, a desktop computer, today's systems include mostly embedded systems, including ARM CPUs used in virtually all smartphones. Systems such as iPhones and Android smartphones frequently include many chips, from many different providers, that include one or more licensed Arm cores, in addition to those in the main Arm-based processor. Arm's core designs are also used in chips that support all the most common network-related technologies. Processors ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Large Physical Address Extensions
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of reduced instruction set computer (RISC) instruction set architectures for computer processors, configured for various environments. Arm Ltd. develops the architectures and licenses them to other companies, who design their own products that implement one or more of those architectures, including system on a chip (SoC) and system on module (SOM) designs, that incorporate different components such as memory, interfaces, and radios. It also designs cores that implement these instruction set architectures and licenses these designs to many companies that incorporate those core designs into their own products. There have been several generations of the ARM design. The original ARM1 used a 32-bit internal structure but had a 26-bit address space that limited it to 64 MB of main memory. This limitation was removed in the ARMv3 series, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Virtualization
In computing, virtualization or virtualisation (sometimes abbreviated v12n, a numeronym) is the act of creating a virtual (rather than actual) version of something at the same abstraction level, including virtual computer hardware platforms, storage devices, and computer network resources. Virtualization began in the 1960s, as a method of logically dividing the system resources provided by mainframe computers between different applications. An early and successful example is IBM CP/CMS. The control program CP provided each user with a simulated stand-alone System/360 computer. Since then, the meaning of the term has broadened. Hardware virtualization ''Hardware virtualization'' or ''platform virtualization'' refers to the creation of a virtual machine that acts like a real computer with an operating system. Software executed on these virtual machines is separated from the underlying hardware resources. For example, a computer that is running Arch Linux may host a virtual machi ...

AnandTech
''AnandTech'' is an online computer hardware magazine owned by Future plc. It was founded in 1997 by then-14-year-old Anand Lal Shimpi, who served as CEO and editor-in-chief until August 30, 2014, with Ryan Smith replacing him as editor-in-chief. The web site is a source of hardware reviews for off-the-shelf components and exhaustive benchmarking, targeted towards computer building enthusiasts, but later expanded to cover mobile devices such as smartphones and tablets.For instance by: * * * * * Its investigative articles have been cited by other technology news sites like PC Magazine and The Inquirer. Some of their articles on mass-market products such as mobile phones are syndicated by CNNMoney. The large accompanying forum is recommended by some books for bargain hunting in the technology field.
