16bit vs 32bit vs 64bit Memory interfacing

Question

In 16 bit processor like 8086, we have the concept of big Endian and small Endian which is related to even and odd bank of memory used in memory address interpretation.

For 32 bit and 64 bit, such mechanism exist or not?

Answer 1

Big-Endian and Small-Endian are  two methods of memory  address interpretation. Every  processor uses one of them to interpret the memory address. The widely used method is Small-Endian.

Small-Endian - Lower address contain lower bits(LSB) and higher address contain higher bits (MSB).

Big-Endian - Lower address contain higher bits(MSB) and higher address contains lower bits(LSB)

Comments

Is it will also applicable on 32bit and 64bit processor? if yes then how?

Memory interpretation has no relation with the word size of a processor.
Memory interpretation tell us how the data is present in the memory cells.
Lets say that the memory is byte addressable and you have to store a hexadecimal number so it will take 2 memory cells to store that lets say their are two memory cells i.e. Cell0 and cell1 and the hexadecimal number is 2842H then 28 will be present in one memory cell and 42 is present in another cell.
Now using little endian
42 is present in cell0 and 28 is present in cell1.
Using big endian 28 is present in cell0 and 42 is present in cell1.
Every processor uses one of them.
Word size of the processor has no relation with this every processor uses memory interpretation.
