Web13 uur geleden · It's timing, however, that animates Spectre. Spectre v2 – the variant implicated in this particular vulnerability – relies on timing side-channels to measure the misprediction rates of indirect branch prediction in order to infer the contents of protected memory. That's far from optimal in a cloud environment with shared hardware.

WebBranch prediction and branch target prediction are often combined into the same circuitry. – Robert Harvey. ... (Combined with the usual need for good normal branch prediction (taken vs. not-taken) for conditional indirect branches). A BTB can also predict where a jump is going before the jmp instruction is even decoded. Web8 nov. 2024 · I was wondering about this. Branch predictors I think generally can handle binary indirect branches -- where there are two immediately visible possible paths the branch could take. However, I was thinking, are branch predictors able to predict indirect function calls, like a virtual function call in C++?
