A method for transferring packets of a communication protocol via a memory-based interface between two processing units. The method includes providing, in each of the processing units, a send area including a read index section, a write index section, and a send buffer, and a receive area including a read index section, a write index section and a receive buffer. Each processing unit repeats as sending steps: reading a read index from the receive area; writing at least one send packet into the send buffer (from a starting write address to an ending write address, the ending write address maximally corresponding to a buffer address assigned to the read read index, and writing a changed write index into the send area.
