Abstract

Reliable General Purpose Dynamic Memory Management for Real-Time Systems
Hong Gao
Kelvin D. Nilsen
Traditional dynamic memory management techniques for
imperative programming languages are unsuitable for reliable
real-time applications because their worst-case time and space
requirements are insufficiently bounded.  This is demonstrated by
detailed measurements of several real-world workloads.
A special hardware-assisted real-time garbage collection system has
been designed to facilitate reliable use of dynamic memory in
hard real-time systems.  By analyzing the dynamic memory use of
application software, the real-time developer can prove compliance
with time and space constraints.  Analysis techniques are presented
and the real-time performance of the hardware-assisted garbage
collection system is compared to that of traditional allocators.
