HiSilicon
HiSilicon () is a Chinese fabless semiconductor company based in Shenzhen, Guangdong and wholly owned by Huawei. HiSilicon purchases licenses for CPU designs from ARM Holdings, including the ARM Cortex-A9 MPCore, ARM Cortex-M3, ARM Cortex-A7 MPCore, ARM Cortex-A15 MPCore, ARM Cortex-A53, ARM Cortex-A57 and also for their Mali graphics cores. HiSilicon has also purchased licenses from Vivante Corporation for their GC4000 graphics core. HiSilicon is reputed to be the largest domestic designer of integrated circuits in China. In 2020, the U.S. instituted rules that require American firms providing certain equipment to HiSilicon or non-American firms who use American technologies that supply HiSilicon to have licenses and Huawei announced it will stop producing its Kirin chipset from 15 September 2020, onwards. HiSilicon has since been overtaken by Chinese rival UNISOC in terms of mobile processor market share. Branch HiSilicon (Shanghai) Technologies CO., Ltd HiSilicon (Shan ...

Jazelle RCT
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, ...

Apple A5
The Apple A5 is a 32-bit system on a chip (SoC) designed by Apple Inc. and manufactured by Samsung. The first product Apple featured an A5 in was the iPad 2. Apple claimed during their media event on March 2, 2011 that the ARM Cortex-A9 central processing unit (CPU) in the A5 is up to two times faster than the CPU in the Apple A4, and the PowerVR SGX543MP2 graphics processing unit (GPU) in the A5 is up to nine times faster than the GPU in the A4. Apple also claimed that the A5 uses the same amount of power as the A4. The last operating system update Apple provided for a mobile device containing an A5 (iPad 2 CDMA, iPhone 4S, and first-generation iPad Mini cellular models) was iOS 9.3.6, which was released on July 22, 2019 as they were discontinued with the release of iOS 10 in 2016. The latest operating system update Apple has provided for an Apple TV containing an A5 ( third-generation Apple TV and third-generation Rev A Apple TV) was Apple TV Software 7.9, which was releas ...

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 ...

QorIQ
QorIQ is a brand of ARM-based and Power ISA-based communications microprocessors from NXP Semiconductors (formerly Freescale). It is the evolutionary step from the PowerQUICC platform, and initial products were built around one or more e500mc cores and came in five different product platforms, P1, P2, P3, P4, and P5, segmented by performance and functionality. The platform keeps software compatibility with older PowerPC products such as the PowerQUICC platform. In 2012 Freescale announced ARM-based QorIQ offerings beginning in 2013. The QorIQ brand and the P1, P2 and P4 product families were announced in June 2008. Details of P3 and P5 products were announced in 2010. QorIQ P Series processors were manufactured on a 45 nm fabrication process and was available in the end of 2008 (P1 and P2), mid-2009 (P4) and 2010 (P5). QorIQ T Series is based on a 28 nm process and is pushing a very aggressive power envelope target, capping at 30 W. These are using the e6500 core with Alti ...

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 ...

Calxeda
Calxeda (previously known as Smooth-Stone) was a company that aimed to provide computers based on the ARM architecture for server computers. It operated from 2008 through 2013. In March 2011 Calxeda announced a 480-core server in development, consisting of 120 quad-core ARM Cortex-A9 CPUs. Calxeda claimed reduced energy consumption as well as better cost per throughput, compared to x86-based server manufacturers. They competed in the many-core server market against Intel and AMD, other recent ARM-based server vendors such as Marvell Technology Group (the Armada XP product), and the multi-core processor manufacturer Tilera. In November 2011 Calxeda announced the EnergyCore ECX-1000, featuring four 32-bit ARMv7 Cortex-A9 CPU cores operating at 1.1–1.4 GHz, 32 KB L1 I-cache and 32 KB L1 D-cache per core, 4 MB shared L2 cache, 1.5 W per processor, 5 W per server node including 4 GB of DDR3 DRAM, 0.5 W when idle. Each chip included five 10 ...

Apple A5X
The Apple A5X is a 32-bit system on a chip (SoC) designed by Apple Inc. and manufactured by Samsung. Apple used it only in the third-generation iPad. The A5X is a high-performance variant of the Apple A5. Apple claimed during their media event on March 7, 2012 that the quad-core PowerVR SGX543MP4 graphics processing unit (GPU) in the A5X is two times faster than the GPU in the A5, as the A5X GPU contains two more cores than the dual-core version GPU in the A5. The last operating system update Apple provided for a mobile device containing an A5X (third-generation iPad cellular models) was iOS 9.3.6, which was released on July 22, 2019 as it was discontinued with the release of iOS 10 in 2016. Design Apple designed the A5X chip specifically for the third-generation iPad to provide the additional graphical performance it required for its new Retina display. The A5X chip features a dual-core 45 nm ARM Cortex-A9 CPU with a clock rate of 1 GHz, and a quad-core 32 nm PowerVR ...
