Recently, the flexible spin-lock model (FSLM) has
been introduced, unifying spin-based and suspension-based resource
sharing protocols for real-time multi-core platforms.
Unlike the multiprocessor stack resource policy (MSRP), FSLM
doesn’t allow tasks on a core to share a single stack, however.
In this paper, we present a hypothesis claiming that for a
restricted range of spin-lock priorities, FSLM requires only two
stacks. We briefly describe our implementation of a dual stack
for FSLM in the Erika Enterprise RTOS as instantiated on an
Altera Nios II platform using 4 soft-core processors.
