利用verilog语言设计实现8路FIR滤波-Using verilog Language Design and Implementation of 8-channel FIR filter

基于用户自定义模块的实时时钟的设计；Qsys硬件设计；(Custom real-time clock module-based design Qsys hardware design )

本书简要介绍了Verilog硬件描述语言的基础知识，包括语言的基本内容和基本结构 ，以及利用该语言在各种层次上对数字系统的建模方法。书中列举了大量实例，帮助读者掌握语言本身和建模方法，对实际数字系统设计也很有帮助。本书是Verilog HDL的初级读本，适用于作为计算机、电子、电气及自控等专业相关课程的教材，也可供有关的科研人员作为参考书。(This book briefly introduces the Verilog hardware description language basics, including basic elements of language and basic structure, and the use of the language at various levels on the digital system modeling. The book lists a large number of examples to help readers master the language itself and the modeling of the actual digital system design is also helpful. Verilog HDL book is a primer for a computer, electronic, electrical and automatic control and other specialized courses related to materials, but also for the researchers as a reference.)

使用Altera公司的FPGA进行VHDL开发。使用quartus2 9.0软件在EP1C3T144C8开发板上实现对4x4键盘的输入控制，并显示在一个8段式数码管上。-The use of Altera" s FPGA-VHDL development. Use quartus2 9.0 software EP1C3T144C8 the development board to realize 4x4 keyboard input control, and displayed in an eight-stage digital pipe.

基于fpga的电子血压计。pdf文档，好用，内容清楚简单，转载而来(Electronic sphygmomanometer based on fpga)

stm32与fpga之间的通信，协议是SPI的，可双向通信（双向通信需要自己例化，只例化了fpga到stm32）(Communication between STM32 and FPGA, the protocol is SPI, two-way communication (two-way communication needs to be taken as an example, only FPGA to STM32))
