Expert RTOS development for FreeRTOS, Zephyr, RT-Thread, and custom schedulers with deterministic timing guarantees.

FreeRTOS, Zephyr, and RT-Thread kernel porting and configuration
Deterministic task scheduling with priority inheritance and preemption
Interrupt service routine optimization for sub-microsecond latency
Memory management with static allocation and MPU protection
Inter-task communication using queues, semaphores, and mailboxes
RTOS-aware debugging with Tracealyzer and SEGGER SystemView
In embedded systems, timing is everything. We reduce interrupt latency and optimize context switching for microsecond precision.
FreeRTOS, Zephyr, RT-Thread — delivering measurable impact through deep technical expertise.
From discrete consulting engagements to full turnkey delivery, we adapt to your program's specific needs and timeline.
ChipTalk's RTOS practice covers the full spectrum from FreeRTOS on Cortex-M to custom POSIX-compliant schedulers on multi-core application processors. Our engineers understand the internals of task scheduling, interrupt nesting, and memory protection at the register level, and have deployed RTOS-based systems in flight-critical, automotive, and medical applications.
Implemented a FreeRTOS-based flight controller with partitioned task scheduling and MPU-enforced memory protection, achieving 1 kHz attitude control loop with deterministic <5 µs jitter.
Developed a safety-critical RTOS system on Zephyr RTOS for a multi-channel infusion pump, implementing IEC 62304 software lifecycle and SIL 2 fault-tolerant task monitoring.
We understand the scheduler—not just how to use it, but how to configure it for your specific real-time constraints. Our RTOS configurations are accompanied by latency-budget analyses and worst-case execution time (WCET) measurements, not just assumptions.
