[solved] – Question 78714

The table below represents the same scenario as part 2 using a write-back cache…
Index V Tag Data Dirty
000 Y 01 Mem[01000] N
001 N N
010 Y 10 Mem[10010] N
011 N N
100 N N
101 N N
110 Y 11 Mem[11110] N
111 Y 00 Mem[00111] N

a) Show the modified table after the following the following sequence of cache accesses (listed by address): {0x1F, 0x1D, 0x08, 0x18, 0x1E}. Assume that underlined accesses correspond to cache writes, while all others correspond to cache reads.
b) Which of the accesses from part 3a result in a read hit?
c) Which of the accesses from part 3a will immediately change a value in memory?
