Abstract: In this paper，a static management allocation strategy for scratchpad memory is proposed based on the energy hotpot of application.With instruction，data and global variable，this method transforms the application into a graph consisting of many distinct nodes based on WECFG，then computes the nodes access energy consumption and the nodes energy density，if nodes is placed in SPM，by SPM’s average access energy consumption.It converts the Integer Iinear Programming（ILP） problem of SPM static allocation to a 0-1 backpack problem.Experiments show that this approach reduces about 34.8% energy consumption than that system without SPM.
