Webprefetching (VLDP) [45] and signature path prefetching (SPP) [33] are well known delta prefetchers. VLDP stores the history of deltas to predict future deltas. SPP is a state-of-the-art delta prefetcher that predicts the non-constant (irregular) strides (commonly known as deltas). SPP works based on the WebAn ideal prefetcher would have both high coverage and accuracy.

"WebThe theory behind this is: RSB is a stack with depth 16 which is filled on every call. On the return path speculation "pops" entries to speculate down the call chain. Once the speculative RSB is empty it switches to other predictors, e.g. the Branch History Buffer, which can be mistrained by user space and misguide the speculation path to a gadget.

Webbased lookahead prefetcher. SPP creates a signature associated with a page address by compressing the history of accesses. By correlat-ing the signature with future likely delta patterns, SPP learns both simple and complicated memory access patterns quickly.

WebPath signature（路径签名），或者叫signature of a path，目前在机器学习和时间序列分析领域中应用广泛。路径签名是粗糙路径理论（Rough Path Theory）的计算结果。很快你将知道路径签名是一个路径的特征，因此可以代替路径本身送入神经网络. WebThe traveling sales rep problem, on the other hand, is O(n!) because you can only find the absolute shortest path between 6 cities by checking all 6! (or 720) possibilities. In real life, we have algorithms that just give "good enough, probably the shortest" answers in much less than O(n!) time.
