In communication systems channel poses an important role. channels can convolve many different kind of distortions to our information. In perticular wireless channels multipath distortion is sevear. and more sevear is such distortion is random. To handle this, multipath affected channels require Equalizers at receaver end. such equalizer uses different learning Algorithms for identifying channels continuously. This project is VHDL implementation of LMS learning algorithm with pipelined architecture. so this implementation can work with higher data rates with less clock speed requirments and so with less power consumpiton It uses Fixed point arithmatic blocks for filtering so suitable for coustom asic.

The emphasis of this book is on real-time application of Synopsys tools, used to combat various problems seen at VDSM geometries. Readers will be exposed to an effective design methodology for handling complex, submicron ASIC designs. Significance is placed on HDL coding styles, synthesis and optimization, dynamic simulation, formal verification, DFT scan insertion, links to layout, physical synthesis, and static timing analysis. At each step, problems related to each phase of the design flow are identified, with solutions and work-around described in detail. In addition, crucial issues related to layout, which includes clock tree synthesis and back-end integration (links to layout) are also discussed at length. Furthermore, the book contains in-depth discussions on the basics of Synopsys technology libraries and HDL coding styles, targeted towards optimal synthesis solution.

To write data to the FIFO, present the data to be written and assert the write enable. At the next rising edge of the clock, the data will be written. For every rising edge of the clock that the write enable is asserted, a piece of data is written into the FIFO. If the FIFO has data in it, the value at the head of the FIFO is present on the FIFO data output. To read data from the FIFO, assert the read enable. At the next rising edge of the clock, capture the data output the FIFO will subsequently advance to the next piece of data stored in the FIFO.

用于仿真进入（由于使用的IN0通道，所以ADDA,ADDB,ADDC均接低电平），经过模/数转换后，产生相应的数字量经过其输出通道D0-D7传送给AT89C51芯片的P1口，AT89C51负责把接收到的数字量经过数据处理，产生正确的7段数码管的显示段码传送给四位LED，同时它还通过其四位I/O口P2.0、P2.1、P2.2、P2.3产生位选信号控制数码管的亮灭。此外，AT89C51还控制ADC0808的工作。其中，单片机AT89C51通过定时器中断从P2.4输出方波，接到ADC0808的CLOCK,P2.6发正脉冲启动A/D转换，P2.5检测A/D转换是否完成，转换完成后，P2.7置高从P1口读取转换结果送给LED显示出来[3]。简易数字直流电压表的硬件电路已经设计完成，就可以选取相应的芯片和元器件，利用Proteus软件绘制出硬件的原理，并仔细地检查修改，直至形成完善的硬件原理图。但要真正实现电路对电压的测量和显示功能，还需要有相应的软件配合，才能达到设计要求。
