ABSTRACT:
A method and apparatus for transferring data between devices on a bus is described, the apparatus comprising a producer device having an output, and a first data management device having an input and a bus interface. An the output of the producer device is coupled to an input of the data management device. An output of the data management device is coupled to the bus. The preferred method of the present invention includes the steps of causing the data management device to receive data packets from the producer device in single address-data phases, grouping at least two data packets destined for consecutive memory addresses, reorganizing the data within the first-in, first-out memory so that the at least two data packets destined for consecutive memory addresses are consecutive in the first-in, first-out memory, and transferring the data group over the bus using a single arbitration phase, a single address phase,. and a number of data phases corresponding to the number of data phases in said group. The present invention allows data from devices which do not support burst data transfers to be transferred in bursts.
