- Drive a speculative version of the branch signal into the IF stage to drive address muxing - The speculative signal is the same as the regular branch signal but assumes all conditional branches are taken - This breaks the timing path from branch condition calculation into address muxing (and therefore PMP error calculation) - When the branch is not taken, any external request we might otherwise have made is suppressed - This has a minor performance cost (0.8% without I$, ~0% with I$) Signed-off-by: Tom Roberts <tomroberts@lowrisc.org> |
