A VANET research program

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.

这是我上大三时的电子设计题目，叫秒表的功能实现。利用ISE软件进行编程，代码是VHDL语言的，可以实现时（0-9）分（0-59）秒（0-59）即最大10小时的计数，对于不同开发板，可以适当修改代码，使之成为更加广泛的计数器。代码纯原创，请下载。
