一个双向总线的vhdl实现-a two-way bus VHDL achieve

该例子是基于sopc的IIC总线设计完整设计，分为硬件和软件部分，软件部分是用c语言编写的。该项目是个以完成的项目，据有较高的参考和经济价值。该例子是原来做过的项目。 整个项目是在Quartus II 7.0和nios IDE环境下开发。 (This example is based on the IIC bus design sopc complete design, divided into hardware and software, the software part is written in c language. The project is to complete the project, according to the reference and a higher economic value. The example is a project originally done. The whole project is in the Quartus II 7.0 and the nios IDE development environment.)

fft变换三个中的一个（站长：三个代码算一个）-one of the three fft transfermation code

it contains pdf file which has vhdl program of uart (universal asynchoronus receiver and transmitter). which very simple and easy to understand

本文介绍了在数字下变频(DDC) 中的抽取滤波器系统设计方法和具体实现方案。采用CIC 滤波器、HB 滤波器、FIR 滤波器三级级联的方式来降低采样率。通过实际验证,证明了设计的可行性(This article describes the digital down conversion (DDC) of the decimation filter system design methods and concrete realization of the program. Using CIC filter, HB filter, FIR filter cascade three-level approach to reduce the sampling rate. Through the actual authentication, to prove the feasibility of the design)

异步的fifo,写时钟和读时钟相互独立，能够对数据进行缓存处理。希望对大家有用(Asynchronous fifo, write clock and the read clock independent of each other, capable of processing the data cache. I hope useful)

以前学习VHDL语言时做的一个电子闹钟程序，可以实现时，分，秒的计时以及定时，校时，闹钟，整点报时的功能。-VHDL language before learning to do procedures in an electronic alarm clock, you can realize hours, minutes and seconds of time and from time to time, school time, alarm clock, the whole point timekeeping function.
