A Branch Target Address Cache (BTAC) stores a plurality of entries, each BTAC entry associated with a block of two or more instructions that includes at least one branch instruction having been evaluated taken. The BTAC entry includes an indicator of which instruction within the associated block is a taken branch instruction. The BTAC entry also includes the Branch Target Address (BTA) of the taken branch. The block size may, but does not necessarily, correspond to the number of instructions per instruction cache line. |
