This project is for Bilkent EEE-102: Introduction to Digital Circuit Design course's term project. I designed a basic CPU which has RISC architecture concept and 3D graphic unit generating 3D objects from lines constituting them instead of planes. All design is implemented on BASYS 3 FPGA card with VHDL. The code of the video game run on the design is written by machine language of the CPU. The shift registers used in controllers unit are 74HC165. VGA communication part is taken from: http://www.ece.ualberta.ca/~elliott/ee552/studentAppNotes/1998_w/Altera_UP1_Board_Map/vga.html
