Very Long Instruction Word Reconfigurable Cipher Processor (VLIW-RCP) has been developed into a new bottleneck where the contradiction between performance and power consumption is becoming fiercer. In this paper, first the power consumption analysis on instruction level of RCP based on the architecture of VLIW is made. Based on the analysis an energy-efficiency evaluation model for the VLIW-RCP is built and also the energy-efficiency evaluation method is purposed. Afterwards, the relation between instruction and energy-efficiency is explored by formula derivation and simulation experiment. As a result, this paper can be used to make a choice of improvement scheme for a new generation Green Computing Reconfigurable Cipher Processor (GC-RCP)
