Parallel processing spacecraft communication system

摘要: An uplink controlling assembly speeds data processing using a special parallel codeblock technique. A correct start sequence initiates of frame. Two possible sequences can be used; and the one which is used determines whether polarity inverted or non-inverted. Processing continues until uncorrectable errors are found. The frame ends by intentionally sending block with an error. Each codeblocks in has channel ID. ID separately processed parallel. This obviates problem waiting for error correction processing. If that number zero, however, it indicates represents critical command only. That handled way, independent software. Otherwise, further double buffering techniques to avoid problems from overrun. When overrun does occur, system takes action lose only oldest data.
