The Cortex-A8 was first introduced in 2005 and was the first processor to support the Armv7-A architecture. Since its introduction, the Cortex-A8 processor has been superseded by the Cortex-A15 and Cortex-A17 processors, but it represents a turning point upwards in the race for efficient high-performance 32-bit compute, and it is still widely deployed in many embedded applications.

The Cortex-A8 processor was the first to use the Armv7-A architecture. Armv7 incorporated three key elements: the Neon single instruction multiple data (SIMD) unit, Arm TrustZone security extensions, and the Thumb-2 instruction set for reduced code size via a mix of 16-bit and 32-bit extensions. The Cortex-A8 implements the extended ISA in the first ever fully superscalar design from Arm. It has a full dual-issue pipeline, meaning the Cortex-A8 can simultaneously issue any two instructions that occur sequentially in the instructions stream whose arguments do not have unresolved dependencies.
The processor has a number of features which make it ideal for use in high-performance end products. A symmetric, superscalar pipeline allows for full dual-issue capability and high-frequency configurations. There is an advanced branch prediction unit with over 95% accuracy, and an integrated L2 cache provides optimal performance in demanding systems. The Cortex-A8 supports Neon technology, allowing it to take advantage of accelerated multimedia and DSP processing.
The Arm Cortex-A8 processor has the ability to scale in speed from 600MHz to greater than 1GHz, meeting the requirements for power-optimized mobile devices needing operation in less than 300mW and performance-optimized consumer applications.
