A novel multimedia extension architecture was proposed to reduce the time overhead of datapermutation caused by conventional SIMD multimedia extension architecture.
为了减少传统SIMD多媒体扩展体系存在的数据置换时间开销，该文提出了一种新的多媒体扩展体系。

Topographic model, deposit solid model, rock and fault solid model are built based on the study on datapermutation and vectorization of original modeling data of Tongchang Copper Mine.
And it ensured the data security and integrity in the protocol entities exchange through encryption, authentication, digital signature and one-way permutation function.
