做fft需要耗费的时钟周期计算如下s_axis_data_tlast- s_axis_data_tvalid ,在ip核中可看到: m_axis_data_tdata:高位为实部,低位为虚部,由于本程序在always内将值给fft_real端口,所以会延迟一个时钟周期,实际为41,fft_real为42; m_axis_data_tvalid:当fft结果输出时拉高,输出2048个点的数据后拉低; m_a...
which is used by the LUT equation. This pin has either been left unconnected in the design or the connection was removed due to the trimming of unused logic. The LUT cell name is: fft_inst/xfft_0_inst/U0/i_synth/axi_wrapper/gen_status_channel.status_fifo/gen_non_real_time.fifo/fifo...
3.在Implementation窗口里,将Control Signals设置ARESETN,在Throttle Scheme设置为Non Real Time 4.Add IP,搜索hls,将搜索到的两个IP添加进设计,然后连接HLS和FFT block的端口(连接如下),然后给hls_real2xfft的din_V_V 接口和Hls_xfft2real的dout_V 接口 选择Make External,添加外部接口并分别命名为eal2xfft_...

zstar_fft_sim文件中用测试脚本的形式,将matlab生成的1000个点cos数据time_domain_cos.txt文本导入,送给FFT IP核进行运算,输出FFT结果的实部和虚部分别存储在fft_result_real.txt和fft_result_image.txt文本中(仿真测试结果位于project\zstar_ex67\zstar.sim\sim_1\behav文件夹下)。
同时,嵌入了RPU(Real-time Processing Unit,实时处理单元),双核Cortex-R5F,主频最高为600MHz。EG和EV系列还嵌入了GPU(Graphics Processing Unit,图形处理单元)Mali-400MP2,主频最高为667MHz。在此基础上,EV系列增强了视频处理功能,嵌入了硬核视频编解码处理单元VCU(Video Encoder/Decoder),可支持H.264/H.265,如...
