Patent ID: 8095740

Claim:
A method for one of inputting data into a message memory of a communication module and outputting data from the message memory of the communication module, the method comprising: providing a connection between the message memory and a buffer memory assemblage, wherein data is configured to be transferred in a first transfer direction to the message memory and in a second transfer direction from the message memory, wherein the buffer memory assemblage has an input buffer memory in the first transfer direction and an output buffer memory in the second transfer direction, and wherein the input buffer memory and the output buffer memory are each divided into a partial buffer memory and a shadow memory; providing a defined register including a first message identifier for a message stored in the partial buffer memory and a second message identifier for a message stored in the shadow memory; and for each transfer direction, performing: inputting the data into the respective partial buffer memory; and transposing access to the partial buffer memory and the shadow memory, so that subsequent data is enabled to be inputted into the shadow memory while the previously inputted data is being transferred from the partial buffer memory in the corresponding transfer direction, wherein the data are transferred in a message that is provided with the first message identifier, and wherein the transposition of access to the partial buffer memory and the shadow memory occurs when the first message identifier is written into the defined register; and upon the transposition of access to the partial buffer memory and the shadow memory, transposing access to the first message identifier and the second message identifier in the defined register.
