貪吃蛇游戲DE1SOC開(kāi)發(fā)板VGA貪食蛇游戲VHDL

名稱：貪吃蛇游戲DE1SOC開(kāi)發(fā)板VGA貪食蛇游戲VHDL（代碼在文末下載）

軟件：Quartus II

語(yǔ)言：VHDL

代碼功能：

經(jīng)典貪食蛇游戲VGA

要求：

1、實(shí)現(xiàn)經(jīng)典的貪食蛇游戲。

2、通過(guò)4個(gè)按鍵控制蛇的方向。

3、果實(shí)可以隨機(jī)產(chǎn)生。

4、每吃到一次果實(shí)，加一分，且蛇變長(zhǎng)。

5、使用VGA顯示游戲圖像。

本代碼采用分模塊設(shè)計(jì)，包括：

• 蛇控制模塊
• 隨機(jī)信號(hào)產(chǎn)生模塊（果實(shí)）
• 計(jì)分模塊
• 導(dǎo)航狀態(tài)機(jī)模塊
• 通用計(jì)數(shù)器模塊
• VGA控制模塊
• 主狀態(tài)機(jī)模塊

本代碼已在DE1-SOC開(kāi)發(fā)板驗(yàn)證，其他開(kāi)發(fā)板可以修改管腳適配，開(kāi)發(fā)板如下：
