It is used LUT as the hardware realized algorithm and is adopted hardware description language(VHDL) and hierarchical,modular design methods to plot entire multi-level functional module and complete all levels of the module design and combine all modules to the whole filter system.It designs FIR filter in parallel and series base on the CPLD.Using MAX + PLUS II software to design,include inputting and processing and checkout for the every administrative levels functional module.It is used waveform editor to draw out the simulation waveform.Let the compiled VHDL program download to the object device.The whole design process is done on the computer,it is facile and fexible,and it reduces the design cycle.
