With the development of computer technology, the processing capability of CPU with traditional architecture cannot address the various computing tasks. There is still room for the performances of heterogeneous computing to be promoted. This study analyzes the idea of "applications make structures, structures make efficiencies", clarifies the conception of mimicry computing, which is based on multidimensional reconfiguration function and dynamic changeable operation system, and then uses the characteristics of programmable hardware, dynamic reconfiguration, and low power of FPGA to design a mimicry computing server which is based on FPGA, and also utilizes the core circuit and critical technology of this mimicry computing server.
