摘要： Method in a pipeline processing stage in a processor, includes the steps of: receiving a first block from a first register and a first execution parameter associated with the first block from a second register, the execution parameter having a first value; inspecting a set of data being at least a part of the first block; and, if the set of data differs from a predetermined condition, storing a second execution parameter on a third register and a third execution parameter on the second register, where the second execution parameter has a second value and is associated with the first block and the third execution parameter has the first value and will be associated with a second block. The invention also relates to the pipeline processor, a module, an integrated circuit and a computer unit.

摘要： The present invention relates to a method and apparatus for pipelined processing of data packets. A pipeline in a processor comprises an access point providing simultaneous access to one or more devices, said devices mainly for data processing operations not provided by the pipeline. The access point comprises at least one FIFO store for storing data entering the access point, a response FIFO store for storing responses received from the device(s), and a synchronization mechanism adapted to synchronize the fetching of the first entry in the FIFO store(s) and the first entry in the response FIFO store. The synchronization mechanism could advantageously be a fixed time delay mechanism. When the fixed time initiated by the fixed time delay mechanism has elapsed, the first response in the response FIFO store is merged into the data stored in the first entry in the FIFO store(s) for storing data entering the access point.

摘要： The invention refers to a method and a processing system for a communications network. The method comprises the step of receiving a program code, comprising a plurality of instructions for the communications network, dividing the program code into a plurality of sequences (7), defining, based on the program code, a plurality of relocation objects (10), each corresponding to a dependency relationship between two or more of the sequences (7), and allocating the sequences (7) to a processor instruction memory (4). Preferably, at least one directed graph is formed, based on at least some of the sequences (7) and at least some of the relocation objects (10), and a longest execution path through the directed graph is determined. Sequences (7) in the instruction memory (4) can be moved and state preserving operations (NOP) can be entered, so as to make at least two execution paths equally long.
