虛編址
英文
virtual addressing-
Adopting the method of top - down, the virtual memory is divided into memory mange related unit ( segment unit and page unit ) and protection mode related unit ( protection test unit, debug test unit and exception detect unit ). data buses and control bused are designed separately for all of the units. vhdl codes are written and simulated
Amex86的虛擬存儲器採用自頂向下的設計方法，把虛擬存儲器劃分為地址管理相關單元（又包括分段單元和分頁單元） 、保護模式相關單元（又包括保護測試單元、調試異常單元利異常檢測單元等） ，分別確立其數據通路和控制通路，完成了vhdl的編碼和模擬工作，通過測試程序模擬驗證了其功能的正確性並測定了基本性能。In this thesis, first, we present the theory of sess system, the generation of the sess spreading code and its characteristics and the acquisition theory of conventional spread spectrum communication system. an efficient acquisition scheme based on periodically transmitting the synchronization head, which is composed of binary chaotic codes, using the matched filter and automatic decision threshold - level control based on a so - called constant false alarm criterion for sess system is present. the acquisition model of sess system is built and simulated in the awgn channel, the raleigh fading channel and imulti - address interfere condition
本文首先概述了自編碼擴頻通信的原理、自編碼擴頻序列的產生方法及其特性和擴頻通信系統編碼同步的理論，然後針對自編碼擴頻通信系統提出了擴頻序列捕獲方案:周期性地加入混沌序列同步碼，並採用恆虛警率匹配濾波器捕獲法;在加性白高斯噪聲通道、瑞利衰落通道和多址干擾情況下進行了模擬，分析了各種捕獲性能:在選擇性能最優的混沌序列、適當的序列長度、虛警概率及門限值的情況下，可以獲得較短的捕獲時間和較大的捕獲概率。The compiler can perform optimizations with indirect calls, such as hoisting the load of a virtual method address out of a loop
，編譯器可以使用間接調用執行優化，如提升循環外虛方法地址的加載。
