基本上,一些架构(X86,说的就是你)除了内存之外,还有一个特殊的、独立的地址空间用于I/O,有其特殊的、不同的指令:在8086上,你会用MOV来读写主内存,用IN/OUT来读写设备。一些设备(最重要的设备:PS/2控制器、软盘、串口...)有一个固定的端口号,其他设备在启动时由BIOS分配一个端口号。在过去,通常的做法是...

PC1:64位 -> 56位 PC2:56位 -> 48位 IP置换、FP置换:64位 -> 64位 E扩展置换:32位 -> 48位,这个置换增加了数据的长度,因此叫“扩展”或“扩张”置换。 P置换:32位 -> 32位 以IP置换为例,置换表长这样: 这个表指出,通过IP置换的新数据的第1位是原始数据的第58位,第2位是原始数据的第50位…...
