摘要
所研究的芯片是128点定点FFT处理器,该处理器主要应用于超宽带无线通信系统.采用一种适合于128点快速傅里叶变换(FFT)的混合基-22/2的按频率抽取算法,并在此基础上设计一种并行运算与流水线结构相结合的硬件系统.详细描述了系统状态机的设计,最终实现了一个满足时序和设计工艺要求,达到了以下指标:工作频率66 MHz,芯片面积3.54 mm2,功耗为71.6 mW的高性能的FFT的IP处理器核.
We introduces the design of 128 -point fixed -point FFT processor which is primarily applied in the MB- OFDM based UWB system,and based on the radix- 22/2 arithmetic of 128 -point Fast Fourier Transform （FFT） , a parallel and pipeline hardware architecture of FFT processor was designed . Then the state machine of the FFT controller was designed. Finally a FFT IP controller core with high performances was realized, which meets the demand timing and design technology and the whole system reaches the following target： the 66 MHz working frequency, the 3.54 mm2 area and the 71.6 mW power dissipation.
