Disclosed is method and apparatus (20) for improving the performance of a pipeline system in which a FIFO (24) is incorporated in the pipeline between an upstream processing module (22) and a downstream processing module (26), each of the modules (22, 26) having access to a common external memory (32), this being typical in many ASIC arrangements. The method commences with detecting when the FIFO (24) is substantially full and transferring commands from the upstream module (22) to the external memory (32). Commands received by the downstream module (26) from each of the FIFO (24) and the external memory (32) are interpreted to determine a source of following ones of the commands.
