WP369可擴展式處理平臺-各種嵌入式系統的理想解決方案 ：Delivering unrivaled levels of system performance,flexibility, scalability, and integration to developers,Xilinx's architecture for a new Extensible Processing Platform is optimized for system power, cost, and size. Based on ARM's dual-core Cortex™-A9 MPCore processors and Xilinx’s 28 nm programmable logic,the Extensible Processing Platform takes a processor-centric approach by defining a comprehensive processor system implemented with standard design methods. This approach provides Software Developers a familiar programming environment within an optimized, full featured,powerful, yet low-cost, low-power processing platform.
Calculation of the Differential Impedance of Tracks on FR4 substrates
There is a discrepancy between calculated and measured values of impedance for differential transmission lineson FR4. This is especially noticeable in the case of surface microstrip configurations. The anomaly is shown tobe due to the nature of the substrate material. This needs to be considered as a layered structure of epoxy resinand glass fibre. Calculations, using Boundary Element field methods, show that the distribution of the electricfield within this layered structure determines the apparent dielectric constant and therefore affects theimpedance. Thus FR4 cannot be considered to be uniform dielectric when calculating differential impedance.
Cimatron E 7.0教程
使用Cimatron E 起草應用，建立部分或者組裝圖圖表是可能的，由2D 風景組成。在畫的每一個內有一條或更多床單，起草的符號和注釋可能被增加并且編輯。 這些畫圖表包含象 起草標準那樣的具體的特性，意見歸因于，框架，模板等等。在各種各樣的起草的概念將的這個練習過程中沿著邊討論Cimatron E的動態的能力。
1、打開一份起草的資料
Open up the Drafting application within Cimatron E.
2、現在起草應用的Cimatron 打開
資料在Cimatron E里使用起草被叫為一張畫。 有一條床單的一張畫被創造一份起草的資料自動創 造。
3、建立床單
一條床單包含一個一個模型，部分或者會議的2D 意見的布局。 除2D之外幾何學建立使用 sketcher，起草符號，注釋能被增加給床單。 無限的床單的數量能被歸入一張畫允許一象要求 的那樣安排許多意見。
This project is created using the Keil ARM CA Compiler.
The Logic Analyzer built into the simulator may be used to monitor and display any variable or peripheral I/O register. It is already configured to show the PWM output signal on PORT3.0 and PORT3.1
This ARM Example may be debugged using only the uVision Simulator and your PC--no additional hardware or evaluation boards are required. The Simulator provides cycle-accurate simulation of all on-chip peripherals of the ADuC7000 device series.
You may create various input signals like digital pulses, sine waves, sawtooth waves, and square waves using signal functions which you write in C. Signal functions run in the background in the simulator within timing constraints you configure. In this example, several signal functions are defined in the included Startup_SIM.INI file.
How to Use Tables With the JTable (in the API reference documentation) class you can display tables of data, optionally allowing the user to edit the data. JTable doesn t contain or cache data it s simply a view of your data. Here s a picture of a typical table displayed within a scroll pane
