本論文係有關基於鏈結串列之霍夫轉換直線偵測演算處理器之軟/硬體整合設計與實現,研究工作包含四大部分:
第一部分為在分析演算法特性並考量嵌入式系統之記憶體資源限制後,發展出基於鏈結串列之霍夫轉換直線偵測演算法,並以C程式語言撰寫相關軟體,以驗證其功能之正確性。
第二部分為設計與開發基於鏈結串列之霍夫轉換直線偵測演算處理器,其組成包括控制單元、來源資料記憶體、有效像素邏輯、座標暨記憶體位址產生器、霍夫參數產生器和基於鏈結串列之霍夫轉換直線偵測演算副處理器。最後,將上述硬體設計整合於可程式系統單晶片中,並實現於Altera FPGA開發板上。
第三部分為實現與驗證基於鏈結串列之霍夫轉換直線偵測演算處理器軟/硬體整合設計,藉由NIOS II整合式開發環境撰寫相關軟體及驅動程式,並進行功能驗證與分析。
第四部分為演算法及演算處理器執行效能之評估。
整體而言,本論文的目標為研究基於鏈結串列之霍夫轉換直線偵測演算法及其演算處理器之軟硬體整合設計與實現,並將之實現於Altera FPGA開發板上,以證實其能顯著地改善原始演算法之執行及記憶體效能。
This thesis is related to the hardware/software codesign and implementation of a linked-list-based Hough-transform algorithmic processor for line detection. The research includes four parts:
The first part is to analyze the property of the algorithm and, after considering that the embedded systems have limited memory resources, a linked-list-based Hough-transform algorithm for line detection has been developed. Also the C language is used to write the program for implementing and verifying the proposed algorithm.
The second part is to design and develop a linked-list-based Hough-transform algorithmic processor for line detection. This algorithmic processor consists of a control unit, a source data buffer, a valid-pixel logic, a coordinate-and-address generator, a Hough-parameter generator, and a linked-list-based Hough-transform algorithmic subprocessor. The algorithmic processor is integrated onto a SOPC-based chip and implemented on an Altera FPGA development board.
The third part is about the hardware/software codesign of a linked-list-based Hough-transform algorithmic processor for line detection. Software and driver programs are developed by using the NIOS II integrated development environment to verify and analyze the function of this algorithmic processor.
The fourth part is to evaluate the performance of the algorithm and the algorithmic processor.
In conclusion, the goal of this thesis is: (1) to develop a linked-list-based Hough-transform algorithm for line detection; (2) to finish the hardware/software codesign and implementation of the HT-based algorithmic processor. Finally, by implementing this algorithmic processor on an FPGA development board, both the modified algorithm and the related algorithmic processor are proved to be more memory-efficient and have better performance.
