FPGA简:讲述了FPGA的基本概念、结构、发展

Basic VHDL code to create a sine wave generator for an FPGA board.

伪随机序列发生器的vhdl算法 设计一个伪随机序列发生器，采用的生成多项式为1+X^3+X^7。要求具有一个RESET端和两个控制端来调整寄存器初值（程序中设定好四种非零初值可选）(m sequence vhdl)

VHDL的源码100例，包括加法、减法、存储、触发等，是初学者、开发人员的必备手册-VHDL source code of the 100 cases, including the addition, subtraction, storage, trigger and so on, is for beginners, developers must Manual

LPDDR2 SDRAM memories compliant to JEDEC JESD209-2.

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.)

说明：  用于FPGA的学习，大家值得借鉴，可以好好学习一下(this is for fpga and you can use this.)

用vhdl实现双向移位寄存器 仿真环境MAXPLUS-II，QUARTUS--bidirectional use VHDL simulation environment shift register Segments-II, QUARTUS-

32位bit输入的CRC32校验，verilog的代码，以及modelsim的testbench代码(The encode of CRC32 with 32bit-inputs based on verilog, and according encode of testbench)

主要编写了一组二进制数据通过根升余弦滤波器后的波形，但并没有使用ISE内部的FIR滤波器内核，该程序相当于编写了一个根升余弦滤波器。(Mainly prepared a set of binary data through the root raised cosine filter waveform after, but did not use the ISE internal FIR filter kernel, the program is equivalent to the preparation of a root raised cosine filter.)

64QAM调制,采用硬件语言verilog实现,其中调用了DDS的IP核(64QAM modulation, using language verilog hardware implementation, which is called the IP core of the DDS)
