− | The miss flag (indicates whether the prediction made by the Branch Predictor was incorrect (asserted). Assertion of this flag indicates that the prediction was incorrect. If unasserted, the values in this interface are undefined.

− | The value is copied from the B_Unit (Bunit_Br_DoneType miss field).

− | BoolType taken (1 bit)
| + | BoolType taken (1 bit) |
− | The taken flag indicates, when the Branch instruction is actually executed, the result of the branch condition. If taken is asserted, the executed branch instruction indicated that the branch should have been taken; if unasserted, the branch should not have been taken. (e.g. Br Taken = 1; Br Not Taken = 0);

− | The target_PC is the branch target address calculated by the FU when the branch instruction is executed.
