Abstract: To solve the problem of exponential space in the instruction-set automated design for the application specific instruction-set processor （ASIP）,a formular clustering integer linear programming model （CIM） is proposed,which can decrease the exploration space effectively utilizing function dependencies between instructions.In addition,implemental strategies are presented for the front-end and back-end in the whole design.The experimental results show that this instruction customization technique can effectively achieve the specific instruction-set automated design,and it can also increase the performance of the final synthesized processor.
