Memory controller that dynamically predicts page misses

摘要: A memory controller dynamically predicts whether a next cycle which is not yet available will result in page miss or hit condition. RAS lines are selectively precharged if the predicted to be miss. The keeps track of various combinations types cycles when type followed by non-memory pending cycle. For each such combination, determines percentage on Using this history, precharges certain combination indicates hits below threshold. If number exceeds threshold, precharging performed.
