1. Page p in the main memory gets mapped to frame f in the cache if and only if p mod 128 = f.
2. Since many pages in the main memory can get mapped to the same frame f in the cache, we need some way to identify which page is in a frame. If the frame is f, the possible pages are all those p in the range 0 to 4095 where p mod 128 is f. For instance, pages 0, 128 and 256 all get mapped to frame 0. Define tag = p/32. So, if tag for frame 0 is 0, it means frame 0 has page 0. If tag for frame 0 is 1, it means frame 0 has page 128. If tag for frame 0 is 2, it means frame 0 has page 256.
