MEMORY OF THE X86 ARCHITECTURE IN A MICROPROCESSOR

The x86 architecture is little-endian, meaning that multi-byte values are written least significant byte first. (This refers only to the ordering of the bytes, not to the bits.) So the 32 bit value B3B2B1B016 on an x86 would be represented in memory as : Little endian representation B0 B1 B2 B3 For example, the 32 bits double word 0x1BA583D4 (the 0x denotes hexadecimal) would be written in memory as : Little endian example D4 83 A5 1B This will be seen as 0xD4 0x83 0xA5 0x1B when doing a memory dump.
