PROFILE
Roman Mazurak
Roman Mazurak enhanced FPU context management and interrupt handling for the ARMv8m main architecture in the zephyrproject-rtos/trusted-firmware-m repository. He implemented logic in C to save and restore S16-S31 FPU registers during context switches, ensuring extended FPU state is preserved safely across partition boundaries. Addressing a potential MemManage fault, he introduced a mechanism to flush lazy stacked FPU registers before partition switches during FLIH mode interrupts. This work improved reliability for multi-partition embedded workloads and demonstrated a deep understanding of ARM architecture, low-level programming, and RTOS internals, resulting in maintainable, auditable firmware changes that reduce fault risk.
