Reconfigurable fast memory management system design for application specific processors

This paper presents the design and implementation of the new active memory manager unit (AMMU) designed to be embedded into system-on-chip CPUs. The unit is implemented using VHDL in field programmable gate array (FPGA) technology. The modified buddy system is used as the hardware algorithm for memory management. A RISC compatible open-source CPU is deployed with the memory management unit to demonstrate the feasibility of implementation. The results indicate that the proposed AMMU achieves high performance in memory allocation and deallocation for software systems.
