Abstract
A prefetch controller is configured to communicate with a prefetch cache in order to increase system performance. The prefetch controller includes an instruction lookup table (ILT) configured to receive a first tuple including a first instruction ID and a first missed data address. The prefetch controller further includes a tuple history queue (THQ) configured to receive an instruction/stride tuple, the instruction/stride tuple generated by subtracting a last data access address from the first missed data address. The prefetch controller further includes a sequence prediction table (SPT) in communication with the tuple history queue (THQ) and the instruction lookup table. The prefetch controller includes an adder in communication with the instruction lookup table (ILT) and the sequence prediction table (SPT) configured to generate a predicted prefetch address and to provide the predicted prefetch address to a prefetch cache.
