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.

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. 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.

SPP is a confidence-based lookahead prefetcher. It creates a signature associated with a page address by com-pressing the history of accesses. http://staff.ustc.edu.cn/~jpq/nvm/2024-DATE-LSP-Collective%20Cross-Page%20Prefetching%20for%C2%A0NVM.pdf

WebSignature Path Prefetcher (SPP) [21] improves VLDP design too. However, it gains performance improvement mainly by increasing the prefetcher depth, which lead to more timely prefetching. LSTMP can be more timely by issuing multiple prefetches upon one demand access, but the main performance gain comes from accuracy improvement. dynamic earth christmas party 2022WebPresented a comprehensive review of PPF using an underlying Signature Path Prefetcher MNIST Digit Detection using Verilog Sep 2024 - Dec 2024.
