CS5460校准程序，控制器为C8051F310，SPI通信协议，可以作为电表芯片示例(CS5460 calibration procedure, the controller for the C8051F310, SPI communication protocol, as the meter chip sample)

11阶fir数字滤波器的verilog程序设计，线性相位，系数量化处理(11 order of fir digital filter verilog programming, linear phase, the coefficient quantization)

这个是讲pll的具体用法的,一般在fpga设计中都会用到 他,这个是lattice的xp2的pll的介绍,不过,fpga 都是相通的其他两家也差不多(Pll say this is the specific usage, the general design in the FPGA will use him, this is the lattice of the pll of xp2 introduction, however, fpga are connected to other two similar)
