Abstract


Digital signal processing is the process that converting the true signal to the information that a computer can process.For example,people’s voice,that is a continuous signal,in addition,in real life there are many such signals,such as optical signals, pressure signals and temperature, etc., while the digital signal processor (DSP) is developed based on these.after the development of these yesrs, DSP’s frequency is gradually increased, and more strengthen capacity, 3G era is to promote the further improvement of DSP processing. The future development of software radio technology, will set higher requirements to the performance of DSP capability.Now FPGA is developing very fast, and is playing an increasingly important role in some areas, so the FPGA’s performance and ability is needed more higher requirements.Many FPGA has been integrated within the DSP, to addressing the signal processing operations. The design is based on the internal FPGA hardware DSP IP, users can use this IP to complete the necessary DSP functions. In this paper the design of DSP to do this in detail.In the hardware DSP, using a multi-stage pipeline, the internal structure of high-speed multiply accumulate, including two improved BOOTH multipliers. Concern to the design verification, using the hierarchical verification strategy, Modelsim is used to simulation and Altera’s FPGA chip is used to verified, Finally use DC synthesis software of synopsys compony to synthesis.and carried out automatically by Astro layout of synopsys compony.
