The Huawei video platform widely supports the ARM architecture. What are the characteristics of the ARM architecture?
A . flat with RISC instruction set length of a national, flexible, and simple addressing modes, high efficiency
B . Many registers are used most of the data operations are completed in the registers, the instruction execution speed is faster
C . It is a new entrant in the field of data center and its ecology is still in a stage of rapid development
D . Using the ARM architecture, the same functional performance occupies a small chip area, low power consumption, higher integration, and more hardware CPU cores have better concurrent performance

Answer: ABCD
