The ARM Cortex-A8 is a processor core designed by ARM Holdings implementing the ARM v7 instruction set architecture. Compared to the ARM11 core, the Cortex-A8 is dual-issue superscalar, achieving roughly twice the instructions executed per clock cycle.

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 (optional)
• VFPv3 Floating Point Unit (optional)
• Thumb-2 instruction set encoding
• Jazelle RCT
• Advanced branch prediction unit with >95% accuracy
• Integrated level 2 Cache (0-4 MB)
• 2.0 DMIPS / MHz

Implementations

Several system-on-chips (SoC) have implemented the Cortex-A8 core, including:

• Apple A4
• Freescale Semiconductor i.MX51 ^[1]
• Samsung Hummingbird
• Rockchip RK29xx ^[2]
• TI OMAP3
