Experimental results show that,compared with full redundancy which replicates full error flow graph,partial redundancy can reduce register usage by 6.25%, reduce power dissipation by over 17%,reduces total execution cycles by nearly 26%,and improves performance by over 22%,at the cost of 6.25% lower nodes coverage.

实验显示，与复制全部错误流图的完全冗余相比，在结点覆盖率降低6.25%的情况下，部分冗余算法最多能够减少寄存器的使用数量6.25%，减少功耗超过17%，减少执行时间接近26%，同时提高性能超过22%。

After power is ON, a central processing unit reads a register value stored in the UIM card detached/attached history detecting unit through a peripheral circuit.

The primitive polynomial of 3-12 pseudo-random sequence generator is obtained after the deductions. The better nonlinear feedback function of all states pseudo-random sequence generator can be picked out according to the characteristic of pseudo- random sequence signal, then using all states of shifting counter through modifying the linear shift register feedback network to realize the all states pseudo-random sequence signal.
