The present invention relates to a method and apparatus for pipelined processing of data. When a data packet containing information is received by a processor operating according to pipelined processing, bits are added to the data packet and an intermediate packet, comprising more bits than the received data packet, is generated. To the intermediate packet is associated information reference, the information reference comprising information regarding the length and position of the information in the intermediate packet. As the intermediate packet is processed, changes to the intermediate packet resulting in changes of the length or the position of the information in the intermediate packet will trigger changes of the information reference. When the intermediate packet exits the processor, superfluous bits are removed.

Method and apparatus for processing data in a pipeline, in which processing the length of information contained in the data packet and/or the position of the information in the data packet is altered

A method in a processor is presented, in which data is processed in a pipelined manner, the data being included in a plurality of contexts, comprising a first (), in addition to which a plurality of operations is adapted to be executed on the contexts. The method comprises executing an initial operation step () of a first operation on the first context (), and subsequently commencing an execution of an initial operation step () of a second operation on the first context before an execution on the first context () of a following operation step () of the first operation is completed.
