was forced by the Instruction Queue. The IQ is also responsible for providing conditional branch prediciton direction based on a static scheme and dynamic data provided by the L2 Branch Prediction Unit. If the conditional branch target is not found in the Target Array and the IQ predicts that the branch is taken, then the IQ will force the Branch Address Calculator to issue a
BACLEAR
. Each
BACLEAR
asserted by the BAC generates approximately an 8 cycle bubble in the instruction fetch pipeline.
