在點(diǎn)陣上顯示自己的名字Verilog代碼Vivado仿真

名稱：在點(diǎn)陣上顯示自己的名字Verilog代碼Vivado仿真

軟件：Vivado

語言：Verilog

代碼功能：

在點(diǎn)陣上顯示自己的名字

1、實(shí)驗(yàn)任務(wù)

在16x16點(diǎn)陣上,編寫 Verilog程序?qū)崿F(xiàn)循環(huán)顯示你自己的“名字”的漢字。

2、實(shí)驗(yàn)結(jié)果與現(xiàn)象

在點(diǎn)陣模塊上循環(huán)依次顯示你自己的“名字”,每個(gè)漢字顯示的時(shí)間約為0.5秒。

3、問題與思考

(1)怎樣讓漢字左旋轉(zhuǎn)和右旋轉(zhuǎn)

(2)怎樣讓漢字左移動(dòng)和右移動(dòng)。

(3) Verilog程序中哪部分,影響每一列的顯示時(shí)間?

(4) Verilog程序中哪部分,影響每一個(gè)字的顯示時(shí)間?
