    • 　　語音翻譯是未來語音與語言技術一個重要的應用，本篇論文提出一個基於ARM微處理器的可程式化系統晶片設計應用於可攜性的語音翻譯，此可程式化系統晶片具有小面積、低成本、即時處理、高可靠度與具靈活性的特性，我們利用一個例句式模板檢索演算法來加快處理速度與節省記憶體需求量，在所提出的語音翻譯可程式化系統晶片設計中，包含了基於AMBA匯流排的可程式化系統晶片架構設計、數位/類比轉換電路設計(包含類比印刷電路板與數位控制電路矽智產)、模板檢索矽智產設計與系統中之軟體處理程序設計，並將整個設計實現於ALTERA公司的EPXA10F1020C2發展平台，在40 MHz的工作時脈下，ㄧ個100句模板的翻譯動作將會在0.5秒內完成，此系統的最大頻率可達46.22 MHz，使用的邏輯元件為19,318 (佔EPXA10全部邏輯元件的50%)。

    　　Spoken language translation is a prospective application of speech and language technology. This thesis presents an ARM-based system on a programmable chip (SOPC) design for a portable spoken language translation application. This SOPC is characterized by small size, low cost, real-time operation, high reliability and flexibility. We adopt the example-based template retrieval algorithm to speed up process and to reduce memory requirement. For SOPC realization of the proposed SLT system, this work designs the AMBA-based SOPC architecture, the AD/DA conversion circuit (include analog PCB and logic controller IP), the template retrieval IP and the software procedures of the SOPC. We implement the entire design with ALTERA EPXA10F1020C2 device. The translation process can be completed within 0.5 second at a 40 MHz clock frequency while the number of templates is 100. The maximum frequency is 46.22 MHz, and the usage of logic elements is 19318 (50% of the total logic elements of EPXA10 device).
