该程序由VC编制，实现FIR数字滤波器功能，为实现数字滤波编程提供了借鉴-The program prepared by the VC, functions of FIR digital filters, digital filter programmed to provide a reference

PLI是实现C程序和硬件语言，包括VHDL，verilog混合编程的接口规范，本例给出VC++环境示范例子，实现VERILOG可以调用C语言函数。-PLI is the specification to perform interface between C and HDL language. This example give a c function called by verilog!
