BENTLY 3500/23E瞬態數據接口PLC模塊
作為參考,以下是一些快速轉換公式:段:偏移到線性地址線性地址=(段×16)+偏移到段的線性地址:偏移段=((線性地址÷65536)?余數)×4096偏移=余數×65536其中余數=(線性地址?65536)的小數部分請注意,單個位置有許多可能的段:偏移地址。上面的公式將通過將段強制到偶數64 KB邊界來提供唯一的段:偏移地址,例如$C00、$E000等。使用此公式時,確保正確舍入偏移計算。VMIVME-7740執行標準IBM PC/AT主板的所有功能,具有以下功能:?單插槽VMEbus 6U大小?包括高性能Intel Pentium III處理器?高達512 Mbyte的同步DRAM?64位AGP SVGA視頻圖形加速器—4 Mbyte SGRAM視頻內存—分辨率高達1600x1200x56k色?電池支持的時鐘/日歷?前面板重置開關和微型揚聲器?鍵盤和鼠標、Ultra IDE硬盤驅動器、軟盤驅動器、雙以太網、視頻、雙串行和USB的車載端口
For reference, here are some quick conversion formulas: Segment:Offset to Linear Address Linear Address = (Segment × 16) + Offset Linear Address to Segment:Offset Segment = ((Linear Address ÷ 65536) ? remainder) × 4096 Offset = remainder × 65536 Where remainder = the fractional part of (Linear Address ÷ 65536) Note that there are many possible segment:offset addresses for a single location. The formula above will provide a unique segment:offset address by forcing the segment to an even 64 Kbyte boundary, for example, $C000, $E000, etc. When using this formula, make sure to round the offset calculation properly.The VMIVME-7740 performs all the functions of a standard IBM PC/AT motherboard with the following features: ? Single-slot VMEbus 6U size ? Includes a high-performance Intel Pentium III processor ? Up to 512 Mbyte of Synchronous DRAM ? 64-bit AGP SVGA video graphics accelerator - 4 Mbyte SGRAM Video Memory - Resolutions up to 1600x1200x56k colors ? Battery-backed clock/calendar ? Front panel reset switch and miniature speaker ? On-board port for a keyboard and mouse, Ultra-IDE hard drive, floppy drive, dual Ethernet, video, dual serial, and USB
