先说明一下内存地址数字情况,主要是为了方便记忆。 可以访问的内存为4G。 0x40000000是1GB处;0x00040000是256K处,0x00020000是128K处,0x90000000是2GB多的地方。 1M->0x00100000, 2M->0x00200000, 8M->0x00800000 16M->0x01000000, 32M->0x02000000 256M->0x10000000 64K->0x00010000 4K->0x00001000 这个是个快速记忆的方法,你可以根据地址中1的位置和其后0的个数来快速知道换算后的地址是在多少兆的地方。比如,1的后面5个0,代表1M的大小,6个0,代表16M,以此类推。 |
