Cortex-A7
The ARM Cortex-A7 MPCore is a 32-bit microprocessor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2011. Overview It has two target applications; firstly as a smaller, simpler, and more power-efficient successor to the Cortex-A8. The other use is in the big.LITTLE architecture, combining one or more A7 cores with one or more Cortex-A15 cores into a heterogeneous system. To do this it is fully feature-compatible with the A15. Key features of the Cortex-A7 core are: * Partial dual-issue, in-order microarchitecture with an 8-stage pipeline * NEON SIMD instruction set extension * VFPv4 Floating Point Unit * Thumb-2 instruction set encoding * Jazelle RCT * Hardware virtualization * Large Page Address Extensions (LPAE) * Integrated level 2 Cache (0–1 MB) * 1.9 DMIPS / MHz * Typical clock speed 1.5 GHz Chips Several system-on-chips (SoC) have implemented the Cortex-A7 core, including: * Allwinner A20 (dual-core A7 + Mali-400 MP2 GPU) * ...

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 ...

Raspberry Pi
Raspberry Pi () is a series of small single-board computers (SBCs) developed in the United Kingdom by the Raspberry Pi Foundation in association with Broadcom. The Raspberry Pi project originally leaned towards the promotion of teaching basic computer science in schools and in developing countries. The original model became more popular than anticipated, selling outside its target market for uses such as robotics. It is widely used in many areas, such as for weather monitoring, because of its low cost, modularity, and open design. It is typically used by computer and electronic hobbyists, due to its adoption of the HDMI and USB standards. After the release of the second board type, the Raspberry Pi Foundation set up a new entity, named Raspberry Pi Trading, and installed Eben Upton as CEO, with the responsibility of developing technology. The Foundation was rededicated as an educational charity for promoting the teaching of basic computer science in schools and developin ...

ARM Architecture
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, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. Pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QorIQ
QorIQ is a brand of ARM-based and Power ISA-based communications microprocessors from NXP Semiconductors (formerly Freescale).
