Abstract
A prefetcher, an operating method of the prefetcher, and a processor including the prefetcher are provided. The prefetcher includes a prefetch address generating circuit, an address tracking circuit, and an offset control circuit. The prefetch address generating circuit generates a prefetch address based on first prefetch information and an offset amount. The address tracking circuit stores the prefetch address and a plurality of historical prefetch addresses. When receiving an access address, the offset control circuit updates the offset amount based on second prefetch information, the access address, the prefetch address, and the historical prefetch addresses, and provides the prefetch address generating circuit with the updated offset amount.
