+ Designing Video Game Hardware in Verilog
+ ++ This book attempts to capture the spirit of the ''Bronze Age'' of video games, when video games were designed as circuits, not as software. +We'll delve into these circuits as they morph from Pong into programmable personal computers and game consoles. Instead of wire-wrap and breadboards, we'll use modern tools to approximate these old designs in a simulated environment from the comfort of our keyboards. +At the end of this adventure, you should be well-equipped to begin exploring the world of FPGAs, and maybe even design your own game console. You'll use the 8bitworkshop.com IDE to write Verilog programs that represent digital circuits, and see your code run instantly in the browser. +
