little endian
For load and store operations in registers and memories there are two arrangement systems in which the bytes are read, the endianness: The little-endian format and the big-endian format.
In contrast to Big Endian, Little Endian is a format for the transmission or storage of binary data in which the Least Significant Byte( LSB) comes first and is stored at the lowest memory address. Thus, the byte E3 of the hexadecimal number 6FE3 is stored in Little Endian format on the memory location with the lowest address.
Intel, DEC's VAX, DEC-Alpha and MIPS chips, among others, work according to this principle.
