籃球比賽計(jì)時(shí)器

在現(xiàn)今的體育比賽中，計(jì)時(shí)器起到至關(guān)重要的作用。為了滿足籃球比賽的計(jì)時(shí)需求，我們設(shè)計(jì)了一款基于FPGA的籃球計(jì)時(shí)器。設(shè)計(jì)各個(gè)功能子模塊，再通過適當(dāng)?shù)慕涌诤托盘柧€進(jìn)行通信和協(xié)調(diào)，最終實(shí)現(xiàn)籃球比賽計(jì)時(shí)器。

設(shè)計(jì)指標(biāo)：

可以進(jìn)行比賽計(jì)時(shí)，具有30秒倒計(jì)時(shí)，倒計(jì)時(shí)通過數(shù)碼管顯示;可通過按鍵對計(jì)時(shí)器清零、置數(shù)、啟動(dòng)和暫停。通過兩個(gè)數(shù)碼管顯示兩隊(duì)比分。

當(dāng)按下復(fù)位信號時(shí)，模塊復(fù)位，按下開始鍵時(shí)開始倒計(jì)時(shí)，按下暫停鍵暫停，再次按下開始鍵時(shí)繼續(xù)倒計(jì)時(shí)，直到倒計(jì)時(shí)為0后，LED閃爍報(bào)警。
