Synopsys® Timing Constraints and Optimization User Guide

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.

URISC 处理器由数据单元和控制单元组成。数据单元中包含保存运算数据和运算结果的数据寄存器，也包括用来完成数据运算的组合逻辑电路单元。控制单元用来产生控制信号序列，以决定何时进行何种数据运算。控制单元要从数据单元得到条件信号，以决定继续进行那些数据运算，数据单元要产生输出信号，数据运算状态等有用信息。-URISC processor by the data unit and control unit. Data unit included in the preservation of data and computing the results of computing the data register, but also data used to complete a combination of computing logic circuit unit. Control unit used to generate the control signal sequence, to determine when and what data computing. Control unit from the data unit received condition signal to determine the continuation of the data computation, data unit to produce output signals, data, such as computing the state of useful information.

电子表，实现计时记分计秒的功能，同时可以对时分秒进行校正，实现调时功能。-Electronic watches, time points of dollars to achieve a second function, at the same time when the minutes and seconds can be calibrated to achieve when the transfer function.
