基于FPGA的频率计设计。通过FPGA运用、 HDL编程，利用FPGA(现场可编程门阵列)芯片设计了一个8位数字式等精度频率计，该频率计的测量范围为0-100MHZ，利用QUARTUS II集成开发环境进行编辑、综合、波形仿真，并下载到CPLD器件中，经实际电路测试，仿真和实验结果表明，该频率计有较高的实用性和可靠性。-Frequency counter FPGA-based design. By using FPGA, VHDL programming, the use of FPGA (fi

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 coproc
