Correlated address prediction
摘要:
A microprocessor having a correlated address predictor, and methods of performing correlated address prediction. A first table memory can be populated by a plurality of buffer entries. Each buffer entry can include a first buffer field to store a first tag based on an instruction pointer and a second buffer field to store an address history. A second table memory can be populated by a plurality of link entries. Each link entry can include a first link field to store a link tag based on an address history and a second link field to store a predicted address. A first comparator can be in communication with the first table memory and an instruction pointer input. A second comparator can be in communication with the first table memory and the second table memory. An output in communication with the second table memory.
