| Summary: | 碩士 === 國立臺灣大學 === 電子工程學研究所 === 106 === In recent year, increasing importance has been attached to FPGAs with the development of AI,VR. To simplify the development process on FPGAs, embedded Linux on FPGAs will be a good way. With UIO driver provided in Linux Kernel, we can mount our block design, that is, custom IP(Intellectual Property) core in Vivado as a device node, and program it in Linux userspace. However, there are some designs that UIO driver cannot recognize. The design with DMA(Direct Memory Access) is one of them. With this kind of design, because UIO driver is not working, we need "root" to control our IP, and providing root privileges to users is never a good solution. In this thesis, we modify UIO driver so that users can easily use designs with DMA in user-space.
