In the face of above cases, this paper attempts to break through the bottleneck of data security with another way. Through study of Error Correction Code and Finite Field theoretics, this paper tries to apply the Reed-Solomom arithmetic based on Finite Field Galois Field to Redundant Array of Independent Disk, and tries to realize a simple RAID6 level programme, thereby could offer an idea for securer storage device.

By analyzing the bode diagram of HAPF system and minimizing the capacity of HAPF, the paper presents a frequency dividing control method based on fuzzy-PI. In this mean generalized integrator is used for frequency dividing integral and fuzzy arithmetic is for adjusting PI coefficients timely. Compare with other kinds of control methods, the proposed one is more simple and easier realization.

In SLDMINV the invariance of the Krylov subspace is invoked, making the main computation reduced into almost real arithmetic, and thus lowering the computation amount markedly. In the meantime, the iteration is performed in the Krylov subspace generated from the inverse of the coefficient matrix and so the convergent speed is enhanced greatly, leading to two orders of the magnitude improvement over standard SLDM.
