ARM 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 the ...

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 ...

Floating-point
In computing, floating-point arithmetic (FP) is arithmetic that represents real numbers approximately, using an integer with a fixed precision, called the significand, scaled by an integer exponent of a fixed base. For example, 12.345 can be represented as a base-ten floating-point number: 12.345 = \underbrace_\text \times \underbrace_\text\!\!\!\!\!\!^ In practice, most floating-point systems use base two, though base ten (decimal floating point) is also common. The term ''floating point'' refers to the fact that the number's radix point can "float" anywhere to the left, right, or between the significant digits of the number. This position is indicated by the exponent, so floating point can be considered a form of scientific notation. A floating-point system can be used to represent, with a fixed number of digits, numbers of very different orders of magnitude — such as the number of meters between galaxies or between protons in an atom. For this reason, floating-poi ...

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. Timeline The following table lists each core by the year it was announced.
