量化卷積神經網路之視訊注視點超解析度成像處理器設計

為了解決full hd 4k的問題，作者黃成漢 這樣論述：

邊緣運算(edge computing)是將人工智慧應用到日常生活很重要的環節，用途包含醫療診斷、穿戴裝置、自駕車等等。相對於將資料傳輸到遠端伺服器處理的雲端計算，邊緣計算少了網路傳輸的延遲，更適合在需要即時處理的應用上。量化可將浮點數(floating-point)神經網路模型轉為bit數小的定點數(fixed-point)模型，可以提升運算效率，並減少存儲空間。而低功耗的藍芽模組(Bluetooth Low Energy, BLE)，成為邊緣裝置傳輸資料的主流。本論文中，我們首先提出了一套方法搜索定點數模型位元寬度(bit-width)以及剪裁值(clipping value)，降低量化

時造成的精確度損失。沒有引介其他參數和額外訓練過程，甚至可以在平均4 bit底下得到極佳的結果，微調量化後的模型權重後還可以達到相同甚至更高的精確度。為了使視訊傳輸達到藍芽低功耗(BLE)的低傳輸率，我們降低傳輸時的解析度，並使用注視點超解析度影片成像技術(foveated video super-resolution)，於邊緣裝置還原回高解析度。本論文提出一個基於卷積神經網路(CNN)的FVSR處理器架構，結合特徵暫存(feature buffer)，就我們所知，本論文為第一個使用空間與時域的特徵的設計。利用層融合(layer fusion)架構降低對DRAM的存儲次數，減少耗能以及存儲的延

遲時間。相比傳統算法，量化後的FVSR模型更能復原細節輪廓。我們使用Xilinx Ultrascale+ ZCU-106現場可程式化邏輯閘陣列(FPGA)驗證系統，使用了178 K個查找表(LUT)與231 K個正反器(flip-flop)，以及265 Kb區塊隨機存取記憶體(Block RAM)。在150 MHz的工作頻率下，本加速器可以15 FPS速率輸出Full HD的影片。

高硬體效能之高度視差範圍雙眼匹配系統之架構與演算法設計

為了解決full hd 4k的問題，作者吳思憲 這樣論述：

精準的3D資訊在電腦視覺的眾多應用中是關鍵技術之一，舉凡自駕車、機器人以及擴增實境。隨著影像解析度的提升，深度圖的視差範圍勢必也需要隨著提升。然而，過往的研究多半專注在如何在既有的測資中進行設計，深度圖的視差範圍(disaprity range)增加而緊接帶來的運算複雜度以及記憶體大小的需求增加並沒有著墨太多。絕大多數的硬體架構，並不適用於大視差範圍的情況，隨著視差範圍的增加，運算複雜度以及記憶體(SRAM)大小往往都會成長至無法負荷。在本論文中，我們著重在提供一個可用於大視差範圍的深度偵測系統演算法以及架構設計。本系統包含高硬體與記憶體效能的基於信心傳遞(Belief-propagatio

n)深度偵測模組以及佔用恆量記憶體的深度圖優化模組。第一個部分提出了用於信心傳遞深度偵測模組高硬體與記憶體的架構。信心傳遞深度偵測演算法因為其規律性以及優良的品質多被選為實現的演算法。然而，我們觀察到目前大多相關架構多因大量記憶體的需求限制以及陷於複雜度以及速度的兩難當中，而無法將其設計擴充支援至更高的視差範圍。這個部份我們提供了兩個技術來分別對應解決這兩個問題。首先，我們藉由觀察信心傳遞演算法的資料特性，設計出高記憶體效能的資料傳遞方式。其次，我們將原有的龐大樹狀比較器架構，置換成由可分享的單位組成，除了大幅降低硬體複雜度之外，同時仍保留低延遲的好處，在現有的架構中取得一個最好的平衡。在這個

部分的架構中，可以將所需要的記憶體降低67.8%。在視差範圍達到512時，更可以節省86.2%的邏輯閘，並且不會帶來對於品質的影響。透過實驗，可以顯示所設計的深度偵測架構更能夠適用於高視差範圍的情況。第二個部分我們提出了一個使用恆量記憶體的深度圖優化硬體架構，可支援極大的高視差範圍，簡稱為CMWMF。這個模組希望解決的是現有深度圖優化引擎都會面臨到的問題：隨著視差範圍隨著影像解析度提升，深度圖優化模組的運算複雜度以及所需要的記憶體大小也同樣的隨之提升。透過觀察以及善用自然圖片中絕大多數都是深度連續的特性，本篇論文提出了可有效降低記憶體需求的硬體架構。此外，我們也希望所提出來的架構能夠支援多種不

同的演算法。該架構包含兩項技術，分別為使用恆量記憶體的硬體架構以及可同時支援三種不同的演算法包含權重極值濾波器、權重中位數濾波器、權重平均濾波器。首先，我們藉由保留最具有指標性的資料，在避免儲存過多資料的同時可以同時降低對於結果的影響。其次，我們改善了權重中位數濾波器運算複雜度過大而難以設計硬體架構的問題，並且將三種不同的演算法融合成雷同的資料流動型態。如此一來，所提出的架構能夠支援三種不同的演算法。在架構中採用了索引檢查的機制用於查找並處理亂序的權重統計資料。融合了以上幾種技術，我們提出了一個使用恆量記憶體的深度圖優化硬體架構並且同時可支援三種不同的濾波器。最終結果該架構可以見少92.4%的

記憶體需求，並且以幾乎無法觀察到的品質下降作為代價。根據既有的測資包含KITTI、Middlebury以及實際由深度相機拍攝取得的深度圖證明，在我們所提出的方法中除了大幅降低演算法的需求之外，亦有保留足夠的資訊所以並沒有大幅的影響品質。
