There is an increasing interest of using the Programmable arrays for performing different hardware. In this paper we give an alternative approach and the applications of the Programmable Gate Arrays. We show the field and the domain where they are more adequate and wihch kind of Programmable array is more efficient to apply. The DPGA and the FPGA are both Programmable Gate Array. They have more possibilities then the conventional devices such as 64 bits microprocessor, however a microprocessor coupled with a programmable array has more opportunity and their implementation is increasing. It is impossible to enumerate all possible uses of Programmable Gate Array. However we use the parameters Latency and throughput. Finite State Machine(FSM), control of data path, processor coupled with a programmable array to build up an alternative approach of the devices and their applications.
