Figure 1 illustrates ARRAY1, the 1024-by-1024 array of eight-byte elements, where the program references 20 elements, then skips over the next 1004, and so forth in a forward direction throughout the array. The reference pattern includes a reference unit of 160 and a gap of 8032 bytes. The reference units begin on every other page boundary.

Every other consecutive page of the data does not come into central storage; those pages contain only the "skipped over" data.
