Mapping Variables to Memory

Mapping Variables to Memory

When you're trying to learn how to address memory, the first challenge is to have a clear mental picture of the storage (the mapping) of variables to memory locations.

Use the following data declarations, and assume that the offset of arrayW is 0000:

.data

arrayW WORD 1234h,5678h,9ABCh ptr1 WORD offset arrayD arrayB BYTE 10h,20h,30h,40h arrayD DWORD 40302010h

file. Print this table, and fill in the hexacecimal contents of every memory location with the correct 32-bit, 16-bit, and 8-bit values.
