Surge in 64-bit computing with ARMv8-A

The latest iPhone5S from Apple is powered by 64-bit SoC A7. A7 significantly boasts iPhone5S performance compared to previous iPhone models. The 64-bit computing is more of a need in high definition video and audio processing. 64-bit computing enables more human interface capabilities to computers and mobile phones, including the speech and visual interface. The 64-bit also makes computation faster in IPv6 networks powering Internet of Things (IoT). What is really pushing 64-bit computing is the availability of 64-bit processor IP core and architecture from ARM. The 64-bit ARMv8-A architecture features larger registers, media instructions, security and cryptography related instructions, and increased addressing range. The two 64-bit processor cores from ARM includes Cortex-A57 and ARM Cortex-A53. Both Cortex-A57 and ARM Cortex-A53 were already popular in designing power efficient servers. They are now competing with x86-based 64-bit servers. Another important factor in driving ARM based servers is the Linux OS support from software companies. The not-for-profit Linaro is making toolchains and software images for AArch64 (the 64-bit execution state of ARMv8) available for Linux OS based server developers. Broadcom has announced the architecture for a new generation of multicore processors based on 64-bit ARM processor cores and ARMv8-A architectural license, Broad...
