基于FPGA的神经网络硬件实现中的关键问题研究，适合用fpga研究神经网络的工程人员参考(FPGA-based hardware implementation of neural networks in the study of key issues for research with neural networks fpga reference works)

这是一个基于FPGA控制点阵板显示的益智趣味类小游戏，游戏中玩家通过键盘↑↓←→键控制控制人物上下左右移动，从起始点出发，目的是走到迷宫的出口。游戏有着友好的用户界面，而且有多种模式，多种地图供玩家选择。 1.普通不计时模式：玩家可以看到整个迷宫地图，游戏没有时间限制； 2.普通计时模式：玩家可以看到整个迷宫地图，必须在20秒内找到出口，否则游戏失败； 3.高级不计时模式：玩家并不能看到整个迷宫的地图，只能看到其周围的2步以内部分路径，其他路径需要靠自己移动来探索，这样就仿佛置身迷宫之中，更有可玩性，游戏没有时间限制； 4.高级计时模式：同样玩家：玩家并不能看到整个迷宫的地图，只能看到其周围的2步以内部分路径；必须在20秒内找到出口，否则游戏失败。

HARQ技术研究，以喷泉码为研究对象，结合LDPC纠错码而研究的。(HARQ technology research to fountain codes for the study, and research combined with LDPC error correction code.)

We present elliptic curve cryptography (ECC) coprocessor, which is dual-field processor with projective coordinator. We have implemented architecture for scalar multiplication, which is key operation in elliptic curve cryptography. Our coprocessor can be adapted both prime field and binary field, also contains a control unit with 256 bit serial and parallel operations , which provide integrated highthroughput with low power consumptions. Our scalar multiplier architecture operation is perform base on clock rate and produce better performance in term of time and area compared to similar works. We used Verilog for programming and synthesized using Xilinx Vertex II Pro devices. Simulation was done with Modelsim XE 6.1e, VLSI simulation software from Mentor Graphics Corporation especially for Xilinx devices.
