Efficient Memory Control for Avionics Systems
نویسندگان
چکیده
Modern aircrafts have seen a significant growth of avionics systems. Most of new aircrafts have systems for navigation, automatic flight control, collision avoidance systems, flight data recorder, weather radar system as well as communication and monitoring systems. All of these systems use embedded computer systems with increasing memory requirements. In order to reduce the electricity consumed by these systems, we suggest detecting the portions of the computer memory that is actually used. The other portion can be temporarily shut down and turn them on again when they are needed. Such a shut down can notably reduce the electricity consumption of the avionics systems.

متن کاملEconomical Memory Management for Avionics Systems
Unlike old-fashioned aircrafts that almost did not have avionics systems, up to date aircrafts have numerous avionics systems. Nearly all new aircrafts have devices for navigation, automatic flight control, collision avoidance systems, flight data recorder, weather radar system in addition to communication and monitoring systems. All of these devices employ embedded computer systems with growin...
متن کاملInteracting Process Classes: Modeling and Simulation
Many reactive control systems consist of a large number of similar interacting objects; these objects can be often grouped into classes. Such interacting process classes appear in telecommunication, transportation and avionics domains. In this paper, we propose a modeling and simulation technique for interacting process classes. Our modeling style uses well-known UML notations to capture behavi...

متن کاملMemory-Efficient Up-the-Ramp Processing with Cosmic-Ray Rejection
We introduce a memory-efficient method for processing up-the-ramp sampled data to reduce noise and remove cosmic-ray events. The method we describe includes initial processing in the readout electronics (onboard, in the case of a space mission) plus postprocessing downstream. This data processing approach can be used to record or downlink high-quality science data using a small fraction of the ...
