Method for high speed framing and a device having framing capabilities
View Patent ↗A device having framing capabilities, the device includes at least one memory unit adapted to store data and metadata required for framing the stored data; the device is characterized by including a framer that is connected to a framed data unit and to a data fetch unit; wherein the device is adapted to select between a first operation sequence and a second operation sequence; wherein the first operation sequence comprises a data chunk and metadata fetch operation followed by a data chunk frame operation and wherein the second operation sequence comprises a multiple data chunk fetch operation followed by multiple data chunk frame operations; wherein the data fetch unit and the framer are adapted to execute the selected operation sequence. A method for framing data, the method includes storing data and metadata required for framing the stored data at one or more memory devices. The method is characterized by executing an operation sequence out of a first operation sequence and a second operation sequence; wherein the first operation sequence comprises a data chunk and metadata fetch operation followed by a data chunk frame operation and wherein the second operation sequence comprises a multiple data chunk fetch operation followed by multiple data chunk frame operations.
1. A device having framing capabilities, the device comprises:
at least one memory unit configured to store data and metadata required for framing the stored data;
the device is characterized by comprising a framer coupled to a framed data unit and to a data fetch unit;
wherein the device is configured to execute a first operation sequence and a second operation sequence;
wherein the first operation sequence comprises a data chunk and metadata fetch operation followed by a data chunk frame operation; and
wherein the second operation sequence comprises a multiple data chunk fetch operation followed by multiple data chunk frame operations;
wherein the data fetch unit and the framer are configured to execute a selected one of a group comprising the first operation sequence and the second operation sequence.
2. The device according to claim 1 wherein the framer is adapted to output multiple framed data chunks during the multiple data chunk frame operation and wherein the framed data unit is configured to ignore at least one of these framed data chunks.
3. The device according to claim 1 wherein the framer is notify the framed data unit an amount of data chunks it concurrently outputs.
4. The device according to claim 1 wherein the framer is configured to output one framed data chunk or two framed data chunks concurrently.
5. The device according to claim 4 wherein the framer comprises a framer status unit configured to request the framed data unit to ignore a single data chunk that is outputted after certain data chunk frame operation and to receive pairs of data chunks that are outputted after a consecutive data chunk frame operation.
6. The device according to claim 1 wherein the framer includes a framed data chunk buffer for temporarily storing one or more framed data chunks.
7. The device according to claim 6 wherein the framer is configured to erase a stored framed data chunk after the stored framed data chunk is accepted by the framed data unit.
8. The device according to claim 1 wherein the framed data unit is configured to generate multiplexes that comprise framed data chunks associated with different communication channels and wherein the framer is adapted to concurrently output framed data chunks that belong to multiple multiplexes.
9. The device according to claim 1 wherein the device includes multiple framers, wherein each framer is included within a RISC processor.
10. The device according to claim 1 wherein the framer is configured to perform error correction operations.
11. A method for framing data, the method comprises:
storing data and metadata required for framing the stored data;
selecting between a first operation sequence and a second operation sequence;
executing the selected operation sequence of the first operation sequence and the second operation sequence;
wherein the first operation sequence comprises a data chunk and metadata fetch operation followed by a data chunk frame operation and wherein the second operation sequence comprises a multiple data chunk fetch operation followed by multiple data chunk frame operations.
12. The method according to claim 11 wherein the executing of the second operation sequence comprises generating multiple framed data chunks during the multiple data chunk frame operations and ignoring at least one of the multiple framed data chunks.
13. The method according to claim 11 wherein the method further comprises sending a notification relating to an amount of valid framed data chunks concurrently outputted by a framer.
14. The method according to claim 11 wherein the second operation sequence comprises two data chunk frame operations.
15. The method according to claim 14 wherein the second operation sequence comprises two data chunk frame operations; and wherein the executing comprises requesting to ignore a single data chunk that is outputted after a certain data chunk frame operation and requesting to receive a pair of data chunks that are outputted after a consecutive data chunk frame operation.
16. The method according to claim 11 wherein the executing comprises temporarily storing one or more framed data chunks.
17. The method according to claim 16 wherein the executing comprises erasing a stored framed data chunk after the stored framed data chunk is accepted by a framed data unit.
18. The method according to claim 11 wherein the executing is followed by repetitively generating multiplexes that comprise framed data chunks associated with different communication channels and wherein the executing comprises concurrently outputting framed data chunks that belong to multiple multiplexes.
19. The method according to claim 11 wherein the framer is configured to perform error correction operations.
20. The method according to claim 11 wherein the executing comprises executing at least one data chunk frame operation by a framer that is configured to frame a single data chunk per one data chunk frame operation.
