Abstract: Multicore dynamically reconfigurable Cache is an important way to solve the Cache-power troubled．Existing Cache-power simulator does not support multi-core dynamic reconfigurable Cache-power research, reconfigurable multi-core dynamic power consumption model of the Cache was researched to find the methods and ideas that can calculate reconstruction Cache. CACTI was used to build the structure of the various components Cache power model to more accurately estimate reconfigurable Cache-power．In Simics simulator,building dynamically reconfigurable Cache,running the test,comparing conventional architectures,reconfigurable Cache power consumption can be obtained a 10.4% decrease．Also it is found that the decrease in power consumption is more than just Dynamically Reconfigurable Cache contribution,but the contribution by the integrated system,prompting a comprehensive consideration of the overall system power consumption and performance in a low-power design,to avoid one-sided consideration of the Cache structure,leading to the improvement of the overall power consumption.
