Adaptive Digital filter based on Least Mean Square (LMS) algorithm is widely used in the field of Digital Signal processing to iteratively estimate the statistics of an unknown signal. Architecture of adaptive filter is based on three major computing elements namely multiplier, adder and delay unit...
However, designing digital signal processing systems for hardware requires design tradeoffs between hardware resources and throughput. You can speed up hardware design and deployment by using HDL-optimized blocks that have hardware-suitable interfaces and architectures, application examples that implement ...
将程序下载到工作频率为50 MHz的Altera Cyclone II EP2C8Q208芯片上。通过Signal Tap II逻辑分析仪,获得实验数据,并将其导入Matlab中进行处理、分析。计算可得,u相输出的实验与仿真结果相关系数为0.99,v也为0.99,可见实验结果和仿真结果高度一致,验证了实验的准确性。 据分析,分布式算法节省了74%的查找表(LUT),75%...
FDATool工具箱具有操作简单、灵活等优点,可以采用多种不同的算法设计实现不同的滤波器,只需要输入设计滤波器的各项参数即可[5]。在MATLAB开始菜单中找到Filter Design打开即可弹出FDATool界面。 根据工程要求,本文设计的滤波器阶数为100阶,通频带是0.5 MHz~9.5 MHz,采样频率选取20 MHz,设计方法采用Equiripple FIR。滤波...

Signal-processing algorithms can be challenging to convert while maintaining required precision, especially if you are writing RTL by hand. The Model-Based Design approach lets you easily explore and visualize different options and automates much of the process. This part of the tutorial sho...
Design.This is the process of creating the hardware logic itself, typically by writing register-transfer logic (RTL) using a hardware description language (HDL) such as VHDL®or Verilog®. The goal is to match the functionality of the algorithm while operating on a continuous stream of data...
