Abstract
A method and arrangement for transferring an indeterminate quantity of data from a target data bus to a requesting data bus. A memory block read command is provided to the target bus by an initiating device coupled to an initiating bus. Successive data segments are repeatedly transferred from the target device into a data buffer which is coupled between the initiating and target buses. The data segments are concurrently transferred from the data buffer to the initiating bus while other data segments are being transferred from the target bus into the data buffer. The transfer is terminated upon receipt of the entire desired data block at the initiating bus, and any read-ahead data remaining in the data buffer after this termination is discarded. The concurrent data transfer is allowed when the memory block read command is not in a delayed completion state, and the command response and requested data are next in the response queue.
