Thirdly , the theory and implementation of related database in the system , which including conception design , logic design and data protection , are discussed emphatically 接著,重點探討了關系數(shù)據(jù)庫的概念設計、邏輯設計的原理、數(shù)據(jù)保護及其在本系統(tǒng)的具體實現(xiàn)。
Besides the logic design , we also divide our system into two parts - background database and forward user ' s interface , and detail the technology design of the two parts respectively 除了對系統(tǒng)經(jīng)行了邏輯設計,在技術上我們將系統(tǒng)分為后臺的數(shù)據(jù)庫與前端用戶程序兩大部分分別經(jīng)行了詳細的論述。
With updated material and references in every chapter , microelectronics , second edition is an essential reference for work with microelectronics , electronics , circuits , systems , semiconductors , logic design , and microprocessors 最新的材料和參考資料,在每章,微電子,第二版是一個重要的參考與微電子,電子,電路,系統(tǒng),半導體,邏輯設計,以及微處理器。
Finally function and timing simulation are accomplished . in the hardware design , ftdi ' s ft245bm device is selected to accomplish usb interface . altera ' s epm7064 device is selected to accomplish jtag interface logic design 在接口電路硬件設計中,選用ftdi公司的usb控制芯片ft245bm ,實現(xiàn)usb物理層和鏈路層協(xié)議的解析, altera的可編程邏輯器件epm7064實現(xiàn)接口邏輯。
The main research work of this dissertation is as following : firstly , two ip logic designs have been accomplished in this dissertation , which are described by verilog hdl , and based on hld ( high - level - design ) technique 對如何編寫仿真測試程序的各種方法進行了介紹,其中著重介紹了一種結構化的仿真測試方法? ?總線功能模型( busfunctionmodel ) ,并將其應用本設計中。
