Prototype Architecture for a VLSI Level Zero Processing System

International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, CaliforniaWhile the complete process of preparing telemetry data for delivery to NASA's customers requires a number of steps or levels (level 0,1,2...etc.), the initial processing, generally referred to as Level Zero Processing (LZP), poses a real technical challenge for NASA in the 1990s Space Station Freedom era. This challenge is the result of requirements to provide real-time or near real-time LZP products at rates up to 150 Mbps. In addition, increased use of sophisticated data formats places even more demand on NASA's future ground telemetry data systems. A new high speed Level Zero Processing system approach has been proposed for the Space Station Information System. By using a new processing algorithm, the complexity of database management necessary for reconstructing payload data streams has been significantly reduced. This new approach is based on the state-of-art distributed real-time processing and VLSI hardware systems and offers potential processing rates up to 150 Mbits per second (Mbps).International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
