Abstract

Claims (23)

1. A processing module for processing user data instructions and control data instructions according to a communication protocol, the processing module comprising a first processor and a second processor wherein:

the first processor is configured to generate user data instructions including a synchronization instruction and control data instructions according to a first process to generate independently from the first process at least further user data instructions including a synchronization instruction and control data instructions according to a second process, to provide the user data instructions and the further user data instructions to be processed by the second processor to the second processor, and to signal validity and completeness of the generated further user data instructions by setting a semaphore; and

the second processor is configured to execute the synchronization instruction to check the semaphore after finishing processing of user data instructions, to process the further user data instructions if the semaphore is set, and to enter an idle state if the semaphore is not set.

2. The processing module of claim 1 ,

wherein the first processor comprises a microcontroller, and

wherein the second processor comprises a co-processor.

3. The processing module of claim 1 , wherein the communication protocol is a communication protocol of a mobile radio communication standard.

4. The processing module of claim 1 , wherein the communication protocol comprises a radio link control layer and a medium access control layer, and the instructions handle data of the radio link control layer and the medium access control layer.

5. The processing module of claim 1 , wherein the processing module further comprises a memory configured to store the instructions provided to the second processor.

6. The processing module of claim 1 , wherein the processing module further comprises:

an interface to a processing module external memory configured to store user data of a communication layer in a form of a source bit stream; and

an interface to a memory in which output data is stored in a form of a target bit stream generated by the second processor according to the instructions.

7. A method for synchronizing the processing of codes, the method comprising:

at least two processes each generating independently from each other codes comprising user data instructions and a synchronization instruction for processing user data according to a communication protocol;

a second of the two processes signaling validity and completeness of generated further code comprising user data instructions by setting a semaphore;

a further process executing the synchronization instruction to check the semaphore after processing of code comprising user data instructions, and

processing further code comprising user data instructions of the second of the at least two processes if the semaphore is set, and entering an idle state if the semaphore is not set.

8. The method of claim 7 , further comprising:

a first of the at least two processes signaling release of its code for processing; and

immediately processing the released code.

9. The method of claim 7 , wherein the code is processed by a co-processor.

10. The method of claim 7 , wherein the code is user data code of a communication protocol layer.

11. The method of claim 10 , wherein the communication protocol layer is a radio link control and/or media access control layer of a mobile radio communication standard.
