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
