a8259 可編程中斷控制 altera提供 The a8259 is designed to simplify the implementation of the interrupt interface in 8088 and 8086 based microcomputer systems. The deviCE is known as a programmable interrupt controller. The a8259 receives and prioritizes up to 8 interrupts, and in the cascade mode, this can be expanded up to 64 interrupts. An asynchronous reset and a clock input have been added to improve operation and reliability.

Modern electronic systems solve so many difficult problems that they often seem like magic. Nonetheless, these systems all have thesame basic limitation: they need a source of electrical power! Most of the time this is a straightforward challenge for the electronicdesigner, because there are many power-delivery solutions. Yet sometimes a deviCE has no direct power source, and running wiresor replacing batteries is impractical. Even when long-life batteries are usable, they eventually need to be replaced, which requires aservice call.

The high defi nition multimedia interface (HDMI) is fastbecoming the de facto standard for passing digitalaudio and video data in home entertainment systems.This standard includes an I2C type bus called a displaydata channel (DDC) that is used to pass extended digitalinterface data (EDID) from the sinkdeviCE (such as adigital TV) to the source deviCE (such as a digital A/Vreceiver). EDID includes vital information on the digitaldata formats that the sink deviCE can accept. The HDMIspecifi cation requires that deviCEs have less than 50pFof input capacitance on their DDC bus lines, which canbe very diffi cult to meet. The LTC®4300A’s capacitancebuffering feature allows deviCEs to pass the HDMI DDCinput capacitance compliance test with ease.

1. 簡介 ISIS中的屬性有非常大的用處。一個特定的對象的屬性是由一些關鍵字組成，比如，在ISIS中，我們使用封裝的屬性與PCB的封裝關聯。 對象，管腳，電路圖都有自己的屬性，如果你想很把這個功能強大的軟件用好你必須很清楚他們之間的聯系，這個軟件和以前你所用過的畫電路的軟件有些不同。 2. 對象屬性 對象屬性有兩個類型—系統屬性和使用屬性。在ISIS中的這些功能是由一些保留字所組成，不管是內部的程序比如ARES和VSM，或者你自己所使用的軟件都是有關聯的。 (1)系統屬性 系統屬性在ISIS中是由一些特殊含義的關鍵字所夠成。比如，一個元件中的deviCE屬性是根據元件庫在分配時候定義的。這些屬性一般是文本的—比如元件的REF和VALUE屬性可以直接從Edit Component對話框中訪問，但是別的比如deviCE屬性就是做為圖形操作所生成的結果。

We intend to develop a wifi enabled p2p file sharing system on a linux platform using jxta and java. The purpose is to build a system that can be ported to an embedded deviCE at a later stage and be used for p2p file sharing using the 802.11b standard. 我們旨在Linux平臺上使用jxta 和java來開發一個支持wifi的p2p文件共享系統。其目的是建造一個以后可以移植到嵌入式設備的系統，使用802.11b標準進行p2p文件共享。 來源: http://sourceforge.net/projects/linux-p2p-wifi/

顯存地址映射。只要知道該類PCI設備的Vendor號，deviCE號和索引號myIndex，就可以查找到該類PCI設備的MEMORY地址和IO地址，以及中斷級。并將第一個MEMORY地址給出它的從物理地址到虛擬地址的映射。
