譯碼樹 的英文怎麼說
中文拼音 [yìmǎshù]
譯碼樹
英文
decoding tree-
Random fields on tree axe applications on trees of theory of random process - a new math model, which develeped from coding and encoding problem in information theory
樹上的隨機場是隨機過程理論在樹-這一最新的數學模型上的應用，它產生於信息理論的編碼和譯碼問題According to the program structure of ansi c, some syntax - tree - nodes are designed in front - end, including function, block, data structure, type, expression, identifier and so on. syntax tree is divided into three levels, namely program level, function level and block level, which are useful for analysis of syntax and semantic in compiler as well as transferring syntax tree into rtl. retargetable compiler mainly includes intermediate representation, machine description and interface technique between compiler and machine description
編譯前端的實現技術包括詞法分析、語法語義分析和中間代碼生成技術等，針對ansic的程序結構，分別設計了函數、塊、數據結構、類型、表達式、標識符等語法樹結點，並將語法樹分成編譯層次、函數聲明和塊三個不同層次，使語法樹具有清晰的層次結構，有利於編譯程序的語法和語義分析，以及從語法樹到rtl中間表示的轉換。I described how the jibx 1. x binding compiler generates bytecode based on a code generation tree structure constructed from the binding definition
中，我描述了jibx 1 . x綁定編譯器如何基於代碼生成樹結構產生位元組碼，這種樹結構是根據綁定的定義構建的。To control the process of adding all the methods and classes described in the last section, the jibx binding compiler first creates an internal representation of each binding in the form of a code generation tree structure
為了控制上一節中描述的所有方法和類的添加過程， jibx綁定編譯器首先用代碼生成樹結構的形式，創建了每個綁定的內部表示形式。You can add new rules, either by writing java code and recompiling pmd or, a little more simply, by writing xpath expressions that are resolved against each java class s abstract syntax tree
您可以添加新規則：可以通過編寫java代碼並重新編譯pdm ，或者更簡單些，編寫xpath表達式，它會針對每個java類的抽象語法樹進行處理。You would never use a scanner to analyze an entire java source ; for that you would turn to something quite familiar to compiler aficionados : the jdt s abstract syntax tree framework
您決不會使用掃描程序分析整個java源代碼；因為您會轉而使用一些對編譯器迷而言十分熟悉的工具： jdt的抽象語法樹（ abstract syntax tree ， ast ）框架。Tree code decoding
樹碼譯碼Decoding algorithm of unequal error protection block code based on tree topology
基於樹狀圖的不等保護分組碼譯碼演算法It also can cooperate with acars system to provide data for oil consume analyse and technique evaluate, etc. this article discuss the working principle and realization of airplane flight safety real time monitor system, the core technology of real time database ( tplus tree index ) in detail, etc. while decoding module is one of the key modules, this article also introduces a high efficiency and easy extending qar data decoding arithmetic, the design and apply to background database, and the relative data load method in this module
本文對飛機飛行安全狀態實時監控系統的工作原理、實時數據庫的關鍵技術（ tplus樹索引）和飛機飛行實時監控系統的實現等，進行了詳細的探討。由於譯碼模塊是該系統的核心模塊之一，同時本文也介紹了一種高效的可擴展的qar數據譯碼平臺的設計和實現，以及后臺數據庫的設計和應用。同時本文也介紹了高效的數據導入的方法以及數據庫的性能優化。( 3 ) combined with probability statistic knowledge, introduce the basic theory of message passing algorithm ; analyse the classical decoding algorithm of ldpc codes, including sum product algorithm which based on probability and llr, and min sum algorithm. ( 4 ) research message passing process on the tree ; according spa, turn the flooding schedule to serial schedule based on c - nodes and v - nodes, namely serial algorithm and, analyse de and complexity ; simulations show that the both serial algorithms could improve decoding performance, improve convergence property, reduce complexity
（ 4 ）研究了和積譯碼演算法在樹上的消息傳遞過程;在ldpc碼經典譯碼演算法基礎上，將洪水消息傳遞機制轉換成基於校驗節點的串列消息傳遞機制和基於變量節點的消息傳遞機制，分別對應串列譯碼演算法和串列譯碼演算法，並對密度進化和譯碼復雜度等方面進行分析;模擬結果表明，兩種串列譯碼演算法都使譯碼性能得到明顯提高，改善了消息收斂特性，降低了譯碼復雜度。分享友人
