Satellite communication system overwriting not validated message stored in circular buffer with new message in accordance with address stored in last valid write address register

摘要

A system for storing and managing messages received at a satellite communications system is disclosed. Messages are sent from a plurality of transmission sources to the system. The message data is received at a plurality of interfaces that verify the accuracy of the data sent, store it in a plurality of RAMs, and then signal a processor that a new message is available for execution. The RAMs are each part of separate message buffers that keep track of the addresses of valid, stored messages and the addresses of the last messages read from memory.
