The data center is a specific device network for global collaboration. It is used to transfer, accelerate, calculate, store and display data information on the basis of Internet.   In recent years, the development of general CPU has been slow, while the scale of data processing and Web service has increased exponentially. Customizable hardware is being used to accelerate common computing, and fast-changing industries require that the customizable hardware be programmable repeatedly to perform new types of computing tasks. FPGA, as a reconfigurable system, has been deployed on a large scale in data centers in recent years.
