基于FPGA实现数控机床高速运动的DDA设计

用FPGA实现的模糊控制器 部分用VHDL编写的源程序-Using FPGA to achieve some of the fuzzy controller using VHDL source code prepared

这里面有许多vhdl的例子，相信对这语言的初学者受益匪浅-There are many examples of vhdl, I believe that beginners benefit from this language

This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM. As of this time, the DDR interface only works up to 120 MHz. At 130, DDR data can be read but not written. NOTE: the test bench cannot be simulated with DDR enabled because the Altera pads do not have the correct delay models. * How to program the flash prom with a FPGA programming file 1. Create a hex file of the programming file with Quartus. 2. Convert it to srecord and adjust the load address: objcopy --adjust-vma=0x800000 output_file.hexout -O srec fpga.srec 3. Program the flash memory using grmon: flash erase 0x800000 0xb00000 flash load fpga.srec-This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM.

串联型有源电力滤波器的 PSCAD仿真，能检测到谐波电压，本仿真的优势是能针对电压跌落或者升高进行自动补偿。(PSCAD simulation of Series type APF (Active Power Filter),this project can dectect the drop of voltage and compensates auomaticly.)

利用VHDL语言编写的一个16分频器，另外可以在程序中修改为任意2N的分频器-use VHDL prepared a 16 dividers, Also in the revision process to be arbitrary 2 N Divider

fpga核心源码，有利于学习，适合初学者学习-fpga core source code, there is conducive to learning, suitable for beginners to learn

基于quartus的3-8译码器,可作为大型系统的译码器模块-Based on quartus a 3-8 decoder can be used as large-scale system decoder module

通过编写verilog语言完成数据的在液晶LCD1602显示(By writing verilog language to complete the data displayed on the LCD LCD1602)
