WebSignature path prefetching (SPP). This state-of-the-art delta prefetcher predicts irregular strides at the L2 cache [35]. SPP works by relying on the signatures (hashes of consecutive strides) observed within an OS page to index into a table that predicts future deltas. SPP uses a lookahead mechanism
