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, and is capable of at most 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 extensionCortex-A8 Specification Summary; ARM Holdings. 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
