Communication system including a first-in-first-out buffer

摘要

A communication system is described for the transfer of messages between a source device and a destination device. There is provided an end-around coupled series of storage control sections, it being possible to chain a non-branching series of messages to each section. There is provided a "busy/not-busy" indicator, a pointer mechanism for indicating a current storage control section for each of the devices, and a notification device which enables the source device with a "signal" in order to signal an activity. Suitable control prevents deadlock and also individual starvation situations.
