The process of ECC includes the selection of base field and coordinates, scalar multiplication and field operation.
ECC算法中基域的选择、坐标系的选择、标量乘法和域算术运算的实现。

A field inversion is the most expensive operation on scalar multiplication, and the number of inversion determines the performance of scalar multiplication.
求逆是标量乘法中最耗时的运算，求逆运算次数的多少直接决定标量乘法的性能。

Usual scalar calculation method can not be well used to make parallel operation on a vector computer.
