indirect addressing

With structure of microcontroller, introduced ways of code optimization, they are technology of OOT and constructed indirect addressing mode with RAM, save considerable code room

结合单片机的结构，介绍了几种代码优化的方法，采用OOT技术和用RAM构造间接寻址方式，可以省下可观的代码空间

The device realizes real time data processing using complex sequence FFT algorithm and bit reversed indirect addressing mode in DSP.

采用复序列快速傅立叶算法，结合DSP处理器中反向进位的间接寻址方式实现了采样数据的快速处理；

X-DSP offers seven basic addressing modes, they are immediate addressing, absolute addressing, accumulator addressing, direct addressing, indirect addressing, memory-mapped register addressing, and stack addressing.

X-DSP提供七种基本寻址方式，分别为立即寻址、绝对寻址、累加器寻址、直接寻址、间接寻址、存储器映射寄存器寻址和堆栈寻址。

Finally, in indexed register indirect addressing mode, both the base and the index are stored in registers.

最后，在索引寄存器间接寻址模式中，基址和索引都保存在寄存器中。
