Cortex-A8
The ARM Cortex-A8 is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture. Compared to the ARM11, the Cortex-A8 is a dual-issue superscalar design, achieving roughly twice the instructions per cycle. The Cortex-A8 was the first Cortex design to be adopted on a large scale in consumer devices. Features Key features of the Cortex-A8 core are: * Frequency from 600 MHz to 1 GHz and above * Superscalar dual-issue microarchitecture * NEON SIMD instruction set extension * 13-stage integer pipeline and 10-stage NEON pipeline * VFPv3 floating-point unit * Thumb-2 instruction set encoding * Jazelle RCT (also known as ThumbEE instruction set) * Advanced branch prediction unit with >95% accuracy * Integrated level 2 Cache (0–4 MiB) * 2.0 DMIPS/MHz Chips Several system-on-chips (SoC) have implemented the Cortex-A8 core, including: * Allwinner A1X * Apple A4 * Freescale Semiconductor i.MX51 * Rockchip RK2918, RK2906 * Samsung Exynos ...

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 (ISAs) for central processing unit, computer processors. Arm Holdings develops the ISAs and licenses them to other companies, who build the physical devices that use the instruction set. It also designs and licenses semiconductor intellectual property core, cores that implement these ISAs. Due to their low costs, low power consumption, and low heat generation, ARM processors are useful for light, portable, battery-powered devices, including smartphones, laptops, and tablet computers, as well as embedded systems. However, ARM processors are also used for desktop computer, desktops and server (computing), servers, including Fugaku (supercomputer), Fugaku, the world's fastest supercomputer from 2020 to 2022. With over 230 billion ARM chips produced, , ARM is the most widely used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
