我用过的verilog hdl写的SDRAM core源程序,经过测试应用

对数计算源程序，能够在FPGA中计算某数的对数(Determined on the basis of the source, calculated in the FPGA to a certain number of log)

设计一个十进制计数器模块，输入端口包括 reset、up_enable 和 clk，输出端口为 count 和 bcd，当 reset 有效时（低电平），bcd 和 count 输出清零，当 up_enable 有效时（高电 平），计数模块开始计数（clk 脉冲数），bcd 为计数输出，当计数为 9 时，count 输出一 个脉冲（一个 clk周期的高电平，时间上与“bcd=9”时对齐）(Design of a decimal counter module, input port, including the reset up_enable clk, output port for the count and bcd, when reset is active (low), the bcd and count output cleared up_enable active (high), count module starts counting the (the CLK pulse number), the BCD count output when the count 9, the count output of the high level, the time of a pulse (a clk cycle with " bcd = 9" when aligned))

奇数分频-此程序对输入频率sysclk有奇数（X）分频的功能(Odd frequency- this program has an odd number of input frequency sysclk (X) frequency function)

基于状态机的优秀SPI输出程序（以DAC7512为基础，可修改）(VHDL code about SPI)

have a good documenty

quartus ii 环境下，一个完整的利用TEXTIO仿真的源代码，包括读数据文件和输出数据到文件。(Under quartus ii environment, a complete simulation using TEXTIO source code, including reading data files and output data to a file.)

MCP4725实现的i2c驱动程序，通过DA转换实现函数发生器(MCP4725 come ture i2c drive program,Through da conversion function generator in English)

适用于满足I2C协议的flash读/写操作程序，只需要设置要读/写的字节数，就可以直接使用！-Applicable to meet the I2C protocol flash read/write operations, only need to set to read/write number of bytes can be used directly!
