AMBA总线apb总线的verilog代码以及相关的中断控制。(AMBA bus apb bus verilog code and associated interrupt control.)

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.

计数器是数字系统中使用最多的时序电路，它不仅能用于对时钟脉冲计数，还可以用于分频、定时、产生节拍脉冲和脉冲序列以及进行数字运算等。(Counter is the most frequently used sequential circuit in digital system. It can be used not only for counting clock pulses, but also for frequency division, timing, generating beat pulses and pulse sequences, and performing digital operations.)
