Raspberry Pi Goes 64-bit

The Pi 3B is based on the Broadcom BCM2837 SoC, which includes a quad-core Cortex-A53 and is capable of 1.2GHz clock frequency. Cortex-A53 comply with the ARMv8A instruction set architecture and support both 64- and 32-bit addressing as well as providing backwards compatibility with the ARMv7 instruction set architecture.
