Running Doom on Our Custom CPU and Going Viral

# Summary A team successfully ran the classic 1993 video game Doom on a custom CPU they built from scratch at the logic gate level, deployed on an FPGA. To overcome the main barriers of insufficient memory (under 1MB vs. Doom's 14MB requirement) and processing speed, they integrated DDR3 memory with a cache system to supplement their original FPGA BRAM design, allowing them to run full published games beyond simple programs like Pong.
