DDR SDRAM控制器verilog代码及中文说明文档

Used for Time shifting discrete signals, it can do both integral and fractional sampling period delay. Original.

说明：  能实现输入0.5 1 5块钱的累加，然后对应购买的商品价格进行比较，显示找的钱数或错误灯(MY English is very good)

通信中加扰/解扰算法。FPGA源代码，verilogHDL语言实现，包含测试程序。(Perturbation/perturbation algorithm. FPGA source code, verilogHDL language implementation, including test procedures.)

说明：  ZYNQ中 PS 端 CAN接口的基本使用方法，并通过 CAN接口实现与 PC 端 CA N调试软件之间的数据接收和发送(The basic use method of PS end can interface in zynq, and the data receiving and sending with PC end can debugging software through can interface)

support for Coldfire m5441x processors.

RISC-V 芯片设计规范,很有参考价值，开源芯片设计必备参考资料，希望对大家有帮助。(The RISC-V Foundation is chartered to standardize and promote the open RISC-V instruction set architecture)

加法器，输入两个整数，用电路图形式将其逻辑原理呈现出来，该加法器为8位运算，每一位都对应一张电路图，可展示其完整过程(Adder, input two integer, with circuit diagram form its logical principle appear, this adder is 8 bit arithmetic, each corresponding to a circuit diagram, can show the complete process)

pid算法控制电机运动，实现fpga与dsp的双口RAM通信(PID algorithm to control motor movement, the realization of FPGA and DSP dual port RAM communication)

APB总线协议转I2C总线协议的接口IP，verilog代码实现，包含详细testbench(APB bus interface to I2C bus interface IP，verilog code )

Verilog HDL 写的SVPWM 算法的实现，使用的是altera 风暴系列的FPGA，占用资源1w+逻辑宏单元(Verilog HDL ，SVPWM)
