圖4-2 實驗評估板接腳
當系統的輸出、輸入接腳從實驗評估板接出來之後，需要適當的元件來做一 個 保 護 ， 避 免 有 不 小 心 誤 動 作 或 是 接 錯 時 會 影 響 到 實 驗 評 估 板 ， 所 以 使 用 PI3C34X245 [12] 來當作輸出、輸入的保護裝置元件，如圖 4-3，此保護裝置元件 有極短的延遲時間（Max：5ns）和非常大的頻寬（BW＞400MHz），所以很適合來當 作保護裝置元件。

圖4-3 保護裝置元件
接著需要將影像感測器接到這片母板，所以需要定義接腳，使其可以透過 FPGA
的效能，未來可以升級或擴充，介面電路如圖 4-4 所示。
另外還有液晶顯示器影像輸出裝置如圖 4-5 也是採用這種設計方式，先定義 FPGA 元件的接腳，來作為輸出裝置的通訊介面。
