An Adaptive Avionics Bus Compression Technique

In order to reduce the data bandwidth in an avionics data bus for effective avioniuc testing, Physical Optics Corporation (POC) proposes to incorporate two unique data processing techniques with a standard lossless data compression scheme. In particular, a neural network based data discrimination technique will be used to recognize the "good" data that is useful to avionic test programs. A genetic algorithm based data optimization techniqie will be used to maximize the data compression ratio even under bursty data traffic. It is expected that the proposed approach will reduce the bus bandwidth required by a factor of 4 - 10 times,while minimizing latency in telementry data streams. Computer simulation will be included in Phase I for a proof-of-principle study, and a trade-off design will be presented for the physical system implementation of POC's proposed approach.
