匯編器在微處理器的驗證和應用中舉足輕重，如何設計通用的匯編器一直是研究的熱點之一。本文提出了一種開放式的匯編器系統設計思想，在匯編語言與機器語言間插入中間代碼CMDL（code mapping description language）語言，打破匯編語言與機器語言的直接映射關系，由此建立起一套描述匯編語言與機器語言的開放式映射體系。基于此開放式映射體系開發了一套匯編器系統，具有較高層次上的通用性和可移植性。【關鍵詞】指令集，CMDL，匯編器，開放式
Design of Retargetable Assembler System Liu Ling FENG Wen Nan Wang Ying Chun Jiang An Ping Ji Li Jiu IME of Peking University, 100871【摘要】An assembler plays a very important role in the field of microprocessor verifications and applications, thus how to build a retargetable assembler system has been a hotspot in this field for long time. This paper presents a new method about the retargetable assembler system design.It provides a kind of language CMDL, code mapping description language. During the process of assembling, assembler languages are firstly translated to CMDL, and then mapped to the machine codes. In an other word, CMDL is inserted between assembler languages and machine codes during the translation procedure. As a medium code, CMDL has a lot of features, such as high extraction, strong descript capabilities. It can describe almost all attributes of assembler languages. By breaking the direct mapping relationship between assembler languages and machine codes, the complexities of machine codes are hided to the users, therefore, the new retargetable assembler system has higher retargetable level by converting the mapping from assembler languages and machine codes to assembler languages and CMDL, and implementationof it becomes easier. Based on the new mapping system structure, a retargetable assemblersystem is developed. It proved the whole system has good retargetability and implantability.【關鍵詞】instruction set, symbol table, assembler, lexical analysis, retargetability

【功能】
1：多用戶統計系統，防止刷新,速度快,適用廣泛
2：綜合統計,最近訪問,地區分析,地址分析,屏幕大小,來訪頁面,訪問次數,操作系統,當前在線,IP地址,瀏覽器,年報表,月報表,周報表,歷史報表,日報表等
3:可以精確的跟蹤統計每一位來訪者的IP與在線時間-同一IP在線每隔5分鐘才能增加一個計數(你也可以修改時間，在stat.jsp頁你把ExTime改為你想要的時間，即 int ExTime=5 )。
4：提供詳細IP數據包，讓你清楚的知道來訪者是來是何方。
最好的是它時時性，你可以監控道現在有誰在瀏覽你的網站，瀏覽你的那個欄目
