基于FPGA的hdb3编码实现

这是用verilog语言实现的1024点ff程序t-This is achieved using Verilog 1024 language ff procedures point t

说明：  该代码，只用了硬件描述语言Verilog在完成对SD卡控制器的编写，经济实用(The code, only the hardware description language Verilog in the completion of the SD card controller to prepare, economical and practical)

verilog jtag源码及原理，还有debug模块。边界扫描等(verilog jtag source and principle, as well as debug module. Boundary-Scan, etc.)

说明：  基于蜂鸟E203riscv系统的DMA外设代码(DMA code based on hbird_e203 system)

Ethernet 10GE MAC 以太网10G的MAC Verilog代码实现(Ethernet 10GE MAC)

超低速的光纤一体发接收发送器,同于以前的光纤一体化接头都只适用于2M以上的通讯,如需将232等低速信号用光纤传输出,需要加复杂的调制解调电路,网动光电新生产的这款光纤头主要针对低速信号,可以传送DC-500KPS的信号,极大地简化了硬件设计.(Ultra-low-fat whole-speed fiber-optic transmitter receiver with fiber-optic integration in the previous joint only applies to more than 2M communications, etc. For the 232 low-speed optical fiber transmission of signals, the need to increase the complexity of the modulation and demodulation circuit, the net move Photoelectric new production of this first major response to low-speed fiber-optic signal, DC-500KPS can send the signal, greatly simplifying the hardware design.)

(2,1,9)卷积编解码器，译码部分采用Vitebi译码算法，设计使用Verilog HDL语言，在Modelsim平台下仿真通过-(2,1,9) convolutional codec, decoding part decoding algorithm used Vitebi design using Verilog HDL language simulation in ModelSim platform through

说明：  matlab代码，利用Farrow结构设计分数延时滤波器，滤波器阶数和个数可分别进行设置，利用最大最小准则近似。(Matlab code, using Farrow structure design fractional delay filter, filter order and number can be set separately, using the maximum and minimum criterion approximation.)

说明：  基于altera fpga的fir IP核实现希尔伯特变换，有matlab仿真(Based on Altera FPGA fir IP core to achieve Hilbert transform, matlab simulation)
