GPU support in MSIM

This thesis presents the design and implementation of graphical device support for the MSIM simulator, addressing the limitation of text-only output in the existing system. We developed two complementary graphical devices: a non-DMA device with individual pixel addressing and a DMA-based device utilising Direct Memory Access for full-screen rendering. We were inspired by current and past graphical devices, chose an appropri- ate graphics library for the task, and designed interfaces that balance educational and practical use. The resulting implementation of the devices enables students and MSIM users alike to create simple graphics applications, display memory contents, print text, and render simple shapes.
