What is cortexa7?

Cortex-A7 is a low-power, high-performance ARMv7-A based microprocessor core from ARM Holdings. It is designed for efficient power usage and is typically used in mobile devices, such as smartphones and tablets. Cortex-A7 includes a NEON SIMD engine for accelerating multimedia and signal processing applications, and has a 1-4 core multi-processing capability. The Cortex-A7 is often paired with the Cortex-A15 core in big.LITTLE configurations to provide a balance of high-performance and power efficiency. It was first introduced in 2011 and has since been used in a wide range of devices.
