"Endian" in Processors?

Status
Not open for further replies.
Little Endian and Big Endian, is the way that the processor stores data in the memory.

When you have data that is bigger than 8 bits, for example:

int data=0x1234; // 16 bits long
long data1=0x12345678 // 32 bits long

If your processor is big endian, the data will be stored in memory as:

int data = 0x1234
Dir 0 = 0x12
Dir 1 = 0x34

long data1 = 0x12345678

Dir 0 = 0x12
Dir 1 = 0x34
Dir 2 = 0x56
Dir 3 = 0x78

But, if the processor is Little endian, data will be stored as

int data = 0x1234

Dir 0 = 0x34
Dir 1 = 0x12

long data1 = 0x12345678

Dir 0 = 0x78
Dir 1 = 0x56
Dir 2 = 0x34
Dir 3 = 0x12

Hope it helps you
