|Architecture and classification|
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.
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
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 3110
- TI OMAP3
- TI Sitara ARM Processors
- Conexant CX92755
