Efficient memory control for avionics and embedded systems

Abstract

Abstract: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 portion of the computer memory that is actually used. The other portion can be temporarily shut down and turned on again when needed. Such a shut down can notably reduce the electricity consumption of the avionics systems.

Can Flight Data Recorder Memory Be Stored on the Cloud?

“…A common difficulty is when FDRs run out of memory space (Weisberg & Wiseman, 2013). Because the designers of the FDR are concerned about this lack of memory, they design the FDRs' memory management process to make a constant effort to reduce the used memory space (Wu, Banachowski, & Brandt, 2005).…”

Virtual Memory Systems Should use Larger Pages

“…A small page size will be selected for a small spatial locality with the purpose of saving memory and a large page size will be selected for a large spatial locality with the purpose of enlargement of the TLB coverage. The spatial locality of an information segment can be analyzed as we suggested at [13].…”

Noise Abatement at Ben-Gurion International Airport

“…The actual altitude is measured by an altimeter [5] and recorded in the flight data recorder [6]; yet, the altitude of an airplane can be calculated according to this equation:…”
