3. Supplementary knowledge

3.1 Armv7-a and Armv8-a

The UK arm's CPUs now have two major architectures:
Armv7-a
Armv8-a

The CPU in the ARMV7-A architecture has several CPUs cortex A5, A7, A8, A9, A12, A15, A17. A5, A7, A8, A9 are low-consumption performance, A12, A15, A17 are high-consumption performance.
The ARMV8-A architecture has cortex A53, A57. A53 is low power consumption and performance, A57 high performance.

Armv7-a is a 32-bit architecture
The armv8-a is a 64-bit architecture (also 32-bit supported) and is nearly one-fold higher performance than armv7-a.

Qualcomm at this stage all CPUs are based on the armv7-a architecture of self-developed CPUs, such as 200, 400, 600, 800, 801, 805 and so on.
Qualcomm will formally enter the ARMV8-A structure at the end of the year, introducing 615 (8 core A53), 808 (2 core a57+4 A53), 810 (4 nuclear a57+4 nuclear A53)

All CPUs in the discovery phase are based on the armv7-a architecture of the arm public CPU, such as MT6582 (4-core A7), 6592 (8-core A7), 6595 (4-core a7+4-core A17)
At the end of the year, the ARMV8-A structure will be launched to launch the MT6752 (8 core A53).

The Samsung CPU is a public version of the CPU based on the ARMV7-A architecture.

Huawei HiSilicon CPU is a public CPU based on the ARMV7-A architecture.

Other CPU manufacturers such as Broadcom Bo Tong are also research and development based on the arm version of the CPU.

The Apple A7 CPU is a cyclone dual-core CPU developed independently of the ARMV8-A architecture. The upcoming A8 chip is also based on the ARMV8-A architecture, rumored to be a quad-core CPU.

3.2 cortex-a8

The ARM CORTEX-A8 processor is the first application processor based on the ARMV7 architecture and is the highest performing and power efficient processor ever developed by ARM. The rate of the CORTEX-A8 processor can be adjusted in the range of 600MHz to over 1GHz, to meet the requirements of power optimized mobile devices that need to work under 300mW, and to meet the requirements of consumer applications that require the performance optimization of Dhrystone MIPS.
