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.

WebVLDP [9] is a recent prefetcher that tracks complex address patterns. It uses a multilevel delta history to ﬁnd a more accurate match for the future accesses. Another recent work called Signature Path Prefetcher (SPP) [10] also maintains a signature for each page. These signatures are made using the delta history. WebFeb 2, 2024 · In 2011, Proactive Instruction Fetch (PIF) showed that a hardware prefetcher could effectively eliminate all of the instruction-cache misses.

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.

WebSign an image using your private key and upload the image, the signature, and a reference to your public key certificate (the verification metadata). The Image service then verifies that the signature is valid. Create an image in the Compute service, have the Compute service sign the image, and upload the image and its verification metadata.

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).
