indirect addressing

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；

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。

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。
