Abstract


Integrated circuit design and manufacturing technology continues to evolve the digital signal processor is used more and more widely used in communications, computing , consumer electronics and other fields . Meanwhile , the digital signal processing algorithm constantly tends to be complicated , only the signal processor has been difficult to improve performance in some cases to rely on the method of optimization software . In addition, increasing competition a higher demand on the flexibility and development cycle of the digital signal processor . This paper presents the structure of a digital signal processor design and function expansion . The processor has a higher flexibility , data path and instruction set extensions can be based on application requirements . Papers in accordance with the top-down design method , Firstly, the overall structure of the processor core , based on a based on scalable thought completion of the address generating means for decoding module and pipeline control unit to achieve , at the same time to solve the competition the flexibility of the process of verification of this structure . On the basis of the completion of the processor core design , the fast Fourier transform circuit for an extended unit of the digital signal processor function expansion . After large-scale functional verification demonstrates the feasibility of the design of the proposed extension and expansion unit performance optimization results . Test results show that , with high speedup , and parallel the design extended digital signal processor in the implementation of the fast Fourier transform operations . In this paper, the design method of the digital signal processor , a good attempt and exploration, and experience to design more powerful , more flexible structure of the digital signal processor .
