Abstract:
Embedded real-time systems are targeting for economical stack memory usage and predictable execution flows, what is challenging to unify. In this paper, we propose CoStack, a collaborative stack sharing approach across tasks. CoStack allows defining a collaborative stack memory that can be used by a higher prioritized task if the stack runs out-of-memory. Thus, CoStack virtually reduces the stack memory consumption, leading to a lower memory requirement, and concurrently remains predictable, what is desired for real-time systems. This paper presents an experimental evaluation of CoStack, the synthesized results in a Field Programmable Gate Array (FPGA) and some implementation details of CoStack.
