ABSTRACT:
Index prediction is used to access data in a memory array. A virtual address is received at an input. The virtual address is translated to a physical address. The memory array is accessed at a predicted address. A portion of the predicted address is compared to a portion of the physical address. If the portion of the predicted address is different from the portion of the physical address, then the predicted address was an incorrect prediction. The memory array is accessed at the physical address.
