解釋
分段數據組-
After analyzing and comparing different partition rules, md32 pipeline architecture is finally defined, which meets the required instruction function, frequency and timing spec of md32. a complete set of creative design method for risc / dsp md32 micro - architecture is presented, such as parallel design, internal pipeline, central control, etc. thanks to the adoption of these design methodology, control path and data path are separated, circuit delay is reduced, and complex instruction operations are balanced among multiple pipeline stages
它們將若干復雜指令操作均勻分配在幾個流水節拍內完成，實現了任意窗口尋址等復雜指令操作，將整個處理器的數據通路與控制通路分離，減小了電路時延，從而滿足了risc dsp不同指令功能和系統時鐘頻率的要求，構成了統一的、緊密聯系的、協調的md32系統結構。 -
Consist of a column or set of columns from the table and are used to allow users to choose how to partition their data
由表中的一列或多列組成，用於使用戶可以選擇如何對他們的數據進行分區。 -
To the problem that finding rules in enormous data is very time - consumable and the expansibility of existed algorithms is not very good, the thesis proposes a new method to discompose large data table based on the concepts of positive region and the importance of attribute in rough set theory. existed algorithms of rule deduction can be applied directly on the tree structure obtained by partition and the times for computation will be reduced observably. validation of information entropy on the partition structure shows that the partition of data table will not lead to the loss of information, while the computing speed increases at the same time, which reflects the practicability and rationality about the partition of large data table
針對海量數據處理起來極為耗時，現有演算法拓展性較差的問題，基於rough集理論中的集合正域概念以及由此定義的屬性重要性概念，提出一種大型數據表分解演算法，現有的規則歸納演算法可直接在分解得到的樹型結構上應用，將大大降低知識發現的時間，並從信息理論的角度利用信息熵概念對該分解結構進行了驗證，分析了這種分解的實用性及合理性，揭示了這種分解結構在提高計算速度的同時不會損失信息量。 -
It is a difficult problem relates to the structure identification of the system and concerns with the partition of the input and output space and the rule generation of the raw sample data. rough set theory, introduced by zdzislaw pawlak in the early 1980s, is another new powerful mathematical tool to deal with vagueness and uncertainty. it can analyze the imprecise, inconsistent and incomplete information effectively, find out the connotative knowledge and detect the potential rule of the system under consideration
由z . pawlak提出的粗糙集理論是一種刻劃不完整性和不確定性的又一個強有力的數學工具，能有效地分析不精確（ imprecise ） 、不一致（ inconsistent ） 、不完整（ incomplete ）等各種不完備的信息，還可以對數據進行分析和推理，從中發現隱含的知識，揭示潛在的規律。 -
Finally, we set up the object oriented data modeling ( oodm ) of the data processing based on c + + object oriented technology ( oot ) and we implemented the unitary architecture designing, its function module partition based on the software framework theory and its program design and development
最後，通過使用軟體體系結構理論中的基於抽象數據類型的面向對象體系結構設計和基於事件隱式調用的結構設計兩種設計方法結合起來，進行各功能模塊的劃分、整體框架的設計，以及具體的的軟體設計和開發工作。 -
Thirdly, we need to build up database to keep the data for data mining, and based on the analysis of economic data warehouse, data table and the problems of data granularity, data partition and the structure of data warehouse, we set the star structure of regional macro economic analysis, and we design the fact table and dimension table for data warehouse. so we design and construct economic data warehouse and fulfill economic data entry, transfer, store and management
在這章中我們給出了一個關于pse的數據倉庫屬性的定義，即：數據倉庫是一種來源於各種渠道的單一的、完整的、穩定的、集成的數據存儲，這個儲存的數據本質上是面向主題的、集成的、非易失的和可動態更新的，數據的邏輯形式是提供公式數據和組織數據。 -
Isa is divided into three parts according to the design consideration of md32. rich addressing and operation modes are supported in md32 isa. risc / dsp pipeline partition rules are given based on the relations between instruction set and data path design
在md32設計中採用了具有自身特色的設計方法，探索出一套面向risc dsp指令結構的微結構設計原則和方法，如并行設計、內部流水設計、集中控制等。
