To save storage space, the game has made a new algorithm design, define a onedimensional array, using a operation state of motion debts storage reading information. Concrete realization, hardware system platform using the 51 series microcontroller, carrying LCD, keyboard and speakers, constitute a lightweight portable game system. 51 series microcontroller mature technology, powerful, wide application. Using single chip microputer as control core can be simplified the hardware circuit and software programming control by microcontroller hardware circuit function, reduce the energy consumption and reduce the cost. The C programming language used in the software, flexibility, accelerated greatly software development speed, shorten the development cycle, and for transplantation. In order to improve the efficiency of development and hardware stability, using a powerful hardware simulation software Proteus, relying on the software provides a simulation environment collocation Keil software development debug environment as simulation debugging success. The article introduces the use ofavariety of hardware features， the game features and the detailed design,software design of the specific ideas， details ofvarious modules， some modu les of the program flow chart， state transition graph,a key part ofthe code details and so on． KeyWords： Greedy Snake； 51MCU； Game III 術 語 表 ALU 算數(shù)邏輯單元。 關鍵詞： 貪吃蛇； 51 單片機；游戲 II Greedy Snake Game Based on 51 MCU design Abstract: With the development of science and technology, modern life rhythm, people more and more quick work life pressure also will increase. Design of a simple operation, the vivid novel strong, easy to carry, entertaining the small game, in a busy work life play this paragraph small game over, not only can adjust people39。為提高開發(fā)效率和硬件穩(wěn)定性，采用了功能強大的硬件仿真軟件 Proteus，依托該軟件提供的仿真環(huán)境搭配 Keil 作為軟件開發(fā)調(diào)試環(huán)境進行仿真調(diào) 試成功。使用單片機作為控制核心，可
