在ＶＨＤＬ上编写了UART通信协议，对于ＦＰＧＡ开发有很大帮助...

（1）能够测试10HZ~10MHZ的方波信号； （2）电路输入的基准时钟为1HZ，要求测量值以8421BCD码形式输出； （3）系统有复位键； （4）采用分层次分模块的方法，用Verilog HDL进行设计，并对各个模块写出测试代码； （5）具体参照说明文档（包含源代码，仿真图，测试波形，详细的设计说明）(A square wave signal capable of testing 10HZ~10MHZ; (2) the reference clock input by the circuit is 1HZ, and the measured value is output in the form of 8421BCD code; (3) the system has a reset key; (4) adopt the method of layering sub sub module and design with Verilog HDL; (5) write test simulation program.)

说明：  This paper analyzes the cryptography scheme of the Trust Platform Model(TPM). The focus of the discussion would be the comparison of elliptic curve cryptography and the nowadays widely used 2048-bit RSA in evaluating which would be better suited to be used on TPM. A TPM implementation scheme based on ECC is proposed, which includes encryption and decryption schemes, signature and verification scheme, key agreement scheme. Corresponding examples of TPM commands would also be given.
