ARM 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 core, the Cortex-A8 is a dual-issue superscalar design, achieving roughly twice the instructions executed per clock cycle. The Cortex-A8 was the first Cortex design to be adopted on a large scale for use in consumer devices.
