The quality of an embedded application depends not only on how well it satisfies functional requirements but also on performance efficiency of the system.
In embedded systems, non-functional requirements like memory requirements, play a very important role, and often impact significantly the embedded system's performance and overall cost of implementation. Embedded Systems usually have constrained resources like memory. Hence, choosing a correct method of verifying memory requirements is extremely critical.
This Paper will give an overview of methodologies for performing different Memory Analyses to determine the correctness and consistency of memory requirements for airborne software and verifying efficient memory usage as required by the RTCA DO-178B guidelines. Different memory analyses methodologies like Memory Map Analysis, Stack Analysis and Heap Analysis are explained with current technology involved.
