![]() ![]() Random Seed - Fills the buffer with random data.Running - It enables you to pause and unpause the game.To load it, select F12 menu and choose load board *.MEM option. It is a simple file containing 2200 x 1125 bytes (visible + invisible area) representing pixels. Loading a boardįirst, copy the board image to your SD card. You can either generate some random seed from the menu (F12, turn random seed on and off) or load an existing board. rbf to the root of your SD card and load it. Also, some cool feats like this amazing digital clock can be constructed.Ĭopy. This is how one of the possible implementations looks like. The fascinating thing is that it is Turing complete and it could, in theory, calculate anything your computer could. That's it! Interesting application note on LFSRs can be found here. The entire game logic can be simplified to one line: Rows are implemented by using altshift_taps component from Intel/Altera, providing a very simple shift register interface (clock, in, out). There are probably better ways to do this, but this one seemed simple enough to use. The whole process then repeats indefinitely. This future cell is shifted into the large shift register and the original cell keeps getting shifted to old row 1 to be used for remaining calculations. This enables direct access to all neighbor cells of cell (1,1) and it is possible to determine the fate of this cell in the next generation. Rows 1 and 2 are deliberately 2 pixels short, and have two separate registers added in front of them. The entire game is implemented as two small shift registers for rows 1 and 2 and a large one which holds the remaining rows. This is not a highly complex FPGA project and should not be viewed as such - it is more of an educational attempt to practice and learn. There are many clever techniques to achieve higher GoL framerates, but the limiting factor is what you can view them on and for most people that's 1080p at 60Hz. The project is designed to run on the MiSTer platform, a very popular and widespread retro gaming system based on the Terasic DE10-Nano FPGA board featuring Intel Cyclone V FPGA chip. ImplementationĬlick on the image to see the project's video output!Īiming for simplicity, the highest possible resolution is aimed at with as few lines of code as possible. Any dead cell with 3 live neighbors becomes aliveįollowing these rules, a new board state can be calculated from the current one and the process goes on indefinitely.Any cell with more than 3 neighbors dies (overpopulation).Any cell with less than 2 neighbors dies (underpopulation).The next grid state is calculated from the present one following few simple rules: It is a game with 0 players placed on an infinite grid where each cell can either be "alive" or "dead". Sadly, he recently passed away due to complications from Covid-19 and this little project is a tribute to him. ![]() Conway (1937 - 2020), an English mathematician is well known for creating a cellular automaton known as the Game of Life. ![]()
