作为一种RISC体系结构的微处理器，ARM微处理器具有RISC体系结构的典型特征。还具有如下增强特点： (l)在每条数据处理指令当中，都控制算术逻辑单元(ALU)和移位器，以使ALU和移位器获得最大的利用率； (2)自动递增和自动递减的寻址模式，以优化程序中的循环； (3)同时Load和Store多条指令，以增加数据吞吐量； (4)所有指令都条件执行，以增大执行吞吐量
-As a RISC microprocessor architecture, ARM RISC microprocessor architecture with typical characteristics. Also has the following enhanced features: (l) in which each data processing instructions, all the control arithmetic logic unit (ALU) and the shifter, ALU and shifter in order to maximize efficiency (2) auto-increment and auto- decrement addressing modes, to optimize the program cycle (3) Load and Store multiple instructions simultaneously to increase data throughput (4) conditional execution of all instructions in order to increase the execution throughput
