Abstract: DSP(Digital Signal Processor) is fit for the field of digital signal processing with the requirement of high performence of real time.This paper proposes an AGU(Address Generation Unit) which can satisfy the special addressing modes of DSP.This AGU also can supports parallel instruction,and realize the operations of arithmetic and address in parallel,which improves the digital signal processing speed efficiently.

Key words: address generation unit, addressing mode, digital signal processor
