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.

當RS-485用于多主通信的總線系統時，多個主機同時發送數據，將會導致數據沖突。為了避免沖突發生，介紹了一種RS-485電路，用簡單硬件實現了總線狀態的檢測，大大降低了數據沖突概率。另外，為了避免總線上的干擾信號影響系統設備，通常需要實現總線與設備內部電路隔離，為此，文中提出了一種新的RS-485電路隔離方案。

以SPI總線技術為基礎，用微控制器S3C2450X和電平轉換芯片MAX3088設計了一個RS-422接口電路，將SPI單端非平衡傳輸信號轉換為RS-422差分信號。在保證SPI同步傳輸的高效性和高速性的同時，還增強了信號的抗干擾能力。 主要使用9 個信號主機輸入G從機輸出C 主機輸出從機輸入 串行時鐘C 或外設片選或從機選擇信號由從機在主機的控制下產生信號用于禁止或使能外設的收發功能為高電平時\" 禁止外設接收和發送數據為低電平時\" 允許外設接收和發送數據! 圖1 所示是微處理器通過與外設連接的示意圖!

This algorithm was developed by Professor Ronald L. Rivest of MIT and can be found presented in several languages. What I provide to you here is a C++ derivative of the original C implementation of Professor Rivets. The library code itself is platform-independant and has been tested in Redhat Linux. I ve included the sample code and makefile that I used for the Linux test. The demo, however, was written with Visual C++ 6 on a Windows 2000 platform.
