증강현실을 위한 임베디드 시스템의 DMA 컨트롤러 설계

An Augmented Reality(AR) provides virtual information with a real environment, and the processor needs to access the memory for the AR system. However, the processor has the heavy workload as the technology improvement leads to increase the size of data. We need a specific module to reduce the workload to overcome the limitation. In this paper, we propose a Direct Memory Access(DMA) controller displaying image instead of the processor. We implemented the proposed DMA controller on a Field Programmable Gate Array(FPGA) and demonstrated the functionality of the DMA controller based on an Avalon Memory Mapped(Avalon-MM) interface. Also, the DMA controller is fabricated by using Magnachip/Hynix 0.35um CMOS technology and verified the feasibility of the embedded system.
