说明：  bnn-fpga是FPGA上CIFAR-10的二进制神经网络（BNN）加速器的开源实现。 加速器针对低功耗嵌入式现场可编程SoC，并在Zedboard上进行了测试。 在编写CIFAR-10测试集中的10000张图像时，错误率是11.19％。(bnn-fpga is an open-source implementation of a binarized neural network (BNN) accelerator for CIFAR-10 on FPGA. The architecture and training of the BNN is proposed by Courbarieaux et al. and open-source Python code is available. Our accelerator targets low-power embedded field-programmable SoCs and was tested on a Zedboard. At time of writing the error rate on the 10000 images in the CIFAR-10 test set is 11.19%.)

read data of type character from flash memory

fpga模拟两路视频，简单拼接后，经过GPIF II接口传出给cy2014，测试usb的吞吐量(fpga generate two lane video, and transmit them through GPIF II interface. test cy2014)

使用VHDL语言实现的一个自动售货机的程序。适合VHDL初学者使用。(VHDL language using a vending machine program. VHDL suitable for beginners.)

说明：  实现二项混合式步进电机的驱动，和步进电机的细分程序。(The driving of binomial hybrid stepper motor and the subdivision program of stepper motor are realized.)

Comparator for Quartus

说明：  可以实现2PSK的信号调制，已经过Modelsim波形仿真(It can realize 2PSK signal modulation and has been simulated by Modelsim waveform.)

LDPC encoder and decoder, very simple
