Abstract
A method of issuing a data retrieval command to a re-order unit in a bus bridge is described. The method requires maintaining an indication of the available (or unreserved) capacity in a data buffer into which a data package is received from a memory resource in response to a data retrieval command. Data packages are furthermore dispatched, relative to other data packages, in the order in which a corresponding data retrieval command is issued from a requesting device. The size of a data package requested by each data retrieval command is determined prior to issuance thereof to the re-order unit. The size of each data package is then compared to the then available capacity in the data buffer, and the relevant data retrieval command is only issued to the re-order unit if the available capacity in the data buffer is sufficient to accommodate the data package requested by the relevant data retrieval command.
