ARM Cortex-A7
ARM Cortex-A7 is a processor commonly found in devices such as the Raspberry Pi 2 micro-computer. It is the successor to Cortex-A8 and is part of the big.LITTLE architecture. The Cortex-A7 is fully feature-compatible with Cortex-A15 and features a dual-issue, in-order microarchitecture. Key features include the NEON SIMD extension and VFPv4 Floating Point Unit.
Some notable chips that use the Cortex-A7 include Allwinner A20, A31, A83T, and H3, Broadcom BCM23550 and BCM2836, NXP Semiconductor QorIQ Layerscape LS1, Freescale i.MX 6 UltraLite, and Mediatek MT6570, MT6582, MT6592, among others. The Cortex-A7 is widely used in various electronic devices due to its performance and efficiency.
