中文摘要 | 本文提出一個以可重組式硬體電路實現歌曲內容檢索系統,本系統採用一個 近似字串比對硬體電路架構,藉由一個簡單的shift-and-or 演算法則為基礎發展的 硬體電路。此系統具有低面積、高效能及低功耗等優點。數據結果顯示本文所提 出硬體架構在大量資料庫或允許錯誤增加之情況下,以硬體執行shift-and-or 演算 法的CPU 運算時間遠比在Pentium IV 以軟體執行低。系統硬體電路架構在Altera 開發板上,量測本電路的功率損耗,在工作頻率增加時,功率損耗只有些微增加。 經由Altera Quartus PowerPlay Early Power Estimator 量測,當工作頻率從10MHz 增加到50MHz,功率損耗的變化從1156.73mW 到1192.32mW,代表本系統之功 率損耗會因工作頻率不同而呈現線性之變化。 |
英文摘要 | This paper proposes a FPGA(field programmable gate array) design and implantation of music retrieval system. The system adopts a novel hardware architecture for approximate string matching. The architecture is based on a simple shift-and-or algorithm. It has the advantages of low area cost, high throughput. and low power. Numerical results show that the proposed architecture has significantly lower CPU time over its software counterpart running on Pentium IV for large database and/or edit distances. Data Result show that the proposed architecture has significantly lower CPU time over its software counterpart running on Pentium IV for large database and/or edit distances. The target FPGA device is Altera Development Board. The power of measurement electric circuit exhausts. As the operating frequency rises to increases from 10MHz to 50MHz, the power consumption only raises from 1156.73mW to 1192.32mW. Representing systematic power consumption will present the linear change because frequency is different. |
