Aiming at the conflict between the RAM access and the design performance,in the four layer C-to-VHDL reconfigurable compiling framework which is based on Low Level Virtual Machine(LLVM) framework,this paper proposes an optimization algorithm for RAM access.By analyzing the load and store instruction in LLVM's IR and the data dependence,it creats a dedicated data path to optimize the process of reading and writing to RAM.Experimental results show that the optimized algorithm can effectively reduce the access number to RAM.
