- A new parameter and a run-time control bit (DataIndTiming and data_ind_timing) enabling different behaviour for running security critical code sections. - In the new mode, all branches act as if taken, with not-taken branches executing as a branch to the next instruction. - This should give similar execution time/power characteristics regardless of the branch condition. - Note that with the BranchTargetALU, branches stall an extra cycle in secure mode to avoid factoring the branch-taken decision into the branch target address mux.
