QFabric: Guarded Cross-Domain Task Recovery and Its Limits on a Linux-RTOS Board
October 31, 2026
QFabric enables task migration between Linux application processors and real-time microcontrollers by treating cross-domain placement as guarded recovery from violated soft real-time contracts. The prototype uses semantic and capacity admission at quiescent epoch boundaries to switch workloads between Cortex-A53 and Cortex-M33 domains on an Arduino UNO Q.
