Abstract
A communications system having a data transfer pipeline apparatus for transferring data in a sequence of N stages from an origination device to a destination device. The apparatus comprises dedicated memory having buffers dedicated for carrying data and a master control for registering and controlling processes associated with the apparatus for participation in the N stage data transfer sequence. The processes include a first stage process for initiating the data transfer and a last Nth stage process for completing data transfer. The first stage process allocates a buffer from a predetermined number of buffers available within the memory for collection, processing, and sending of the data from the origination device to a next stage process. The Nth stage process receives a buffer allocated to the first stage process from the (N−1)th stage and to free the buffer upon processing completion to permit reallocation of the buffer.
