椭圆曲线参数，方便椭圆曲线取基点和阶，a,b的值免去不必要的运算。-Elliptic curve parameters to facilitate take bp and bands of the elliptic curve, a, the value of b to avoid unnecessary operation.

In FS16i/18i/160i/180i/160is/180is-MODEL A and FS15i-MODEL A/B, FANUC will apply a new 3MB SRAM module to systems provided September 2005. Because FANUC adopt the ECC check function instead of the parity check function for increasing reliability
