Method, apparatus, and computer program product for controlling data transfer

摘要

A method, apparatus, and computer program product are described for controlling data transfer. A next data packet to be transferred is retrieved. A determination is made regarding whether a data bus busy signal is asserted. If the data bus busy signal is asserted, a determination is made regarding whether a data bus grant signal is asserted. If the data bus grant signal is asserted, the next data packet is transferred on the next cycle after a last cycle of data transfer of a previous data packet.
