aynchronous fifo 项目

一份带有FIFO缓存的UART源码，采用verilog编写，实现批量数据的传输，数据缓存量可以通过修改源码中的FIFO的深度来改变。(This is a UART with FIFO. The UART is programmed using verilog, it can transmit or receive batch data. The amount of data buffered can be changed by changing the depth of FIFO.)

按键可调占空比的PWM波产生程序。语言：VHDL(Button adjustable duty cycle of the PWM wave generator. Language: VHDL)

RSA加密算法IP，用verilog实现，结构清晰，注释全面，其中包括verilog的源代码，testbench和日文的设计说明文档 ./RSA_tb.v ./RSA1024_RAM.v ./RSASpec2007Oct11.pdf

说明：  利用FPGA实现对外设按键的控制，例如用户库用按键控制跑马灯的效果(FPGA is used to realize the control of external keys, such as the effect of user database using keys to control the running horse lamp)

关于数字电压表的vhdl实现，有仿真程序，可以下载到板子中。(Vhdl digital voltage meter on the implementation of a simulation program can be downloaded to the board.)

说明：  简单的单周期CPU设计，实现的指令有：算术运算指令、逻辑运算指令、移位指令、比较指令、存储器读/写指令、分支指令、跳转指令、停机指令。(Simple single-cycle CPU design,The instructions implemented are as follows:Arithmetic operation instruction, logical operation instruction, shift instruction, comparison instruction, memory read/write instruction, branch instruction, jump instruction, stop instruction.)

有限状态机的一段式、二段式以及三段式写法的对比

stepper motor vhdl pin assignments and code

利用SCCB和FPGA实现视频采集的论文，对相关开发人员具有很强的参考价值！ (FPGA implementation using the SCCB and video collection of the papers, the relevant developer has a strong reference value ! )

xilinx FPGA设计需要的DDR2文件，可以应用于实际设计中(xilinx FPGA design needs DDR2 files that can be applied to the actual design)
