Bosses, several problems-CodePudding

a 32-bit word long memory using small side (low byte address as word), store 32-bit int variable x, 12345678 h, the address is 00002000 h, then the address byte content for the storage?

the answer is 78 h, why? , what's the use of 00002000 h?

CodePudding user response:

Because it is a small back-end storage, low in the lower address,

Well, I know, low is 78 h

What is the use 00002000 h? Is the low address? Why is that?

CodePudding user response:

The small end:
00002000 h: 78
00002001 h: 56
00002002 h: 34
00002003 h: 12

Main:
00002000 h: 12
00002001 h: 34
00002002 h: 56
00002003 h: 78

00002000 h: 78
00002001 h: 56
00002002 h: 34
00002003 h: 12

00002000 h: 12
00002001 h: 34
00002002 h: 56
00002003 h: 78

So the first address is 00002000 h, 12345678 h, is it
