Abstract
A method of determining whether to issue a pre-fetch transaction in a memory control system comprising generating a pre-fetch threshold dependent on a demand load of a memory controller, calculating a probability measure of pre-fetch accuracy, comparing the threshold with the calculated probability measure, and determining whether to issue a pre-fetch transaction based upon the comparison of the threshold with the calculated probability measure is provided. A pre-fetch apparatus implemented in a memory control system comprising a pre-fetch threshold generator operable to output a pre-fetch threshold in response to a signal indicative of a memory controller demand load, and a comparator circuit operable to compare the pre-fetch threshold and a probability measure of pre-fetch accuracy, wherein the pre-fetch apparatus issues a pre-fetch transaction on the basis of the comparison by the comparator is provided.
