高精度小数除法器设计与实现。 在FPGA开发板上实现小数除法器，输入输出信号N_in [15:0], D_in[15:0]，N_in[15:0]小于D_in，即被除数小于除数，输出商Q_out[15:0]中Q[15]一定为0，Q[14:0]为商的小数部分。输入和计算结果通过VGA显示。(Precision fractional divider design and implementation. In the FPGA development board fractional divider, input and output signals N_in [15: 0], D_in [15: 0], N_in [15: 0] less than D_in, ie the dividend is less than the divisor, quotient output Q_out [15: 0] in Q [15] necessarily 0, Q [14: 0] for the business of the fractional part. Input and calculation results display by VGA.)
