Real-Time Operating Systems (RTOS)
We design and implement real-time embedded systems where deterministic behavior and stable timing are critical. RTOS is integrated into the system architecture to ensure predictable execution under real operating conditions.
Measured impact on real-time system behaviour
Our RTOS implementations improve system stability, reduce timing variability and allow predictable execution under load.
How we design deterministic real-time systems
Real-time issues are rarely caused by code alone. They result from architecture, scheduling and hardware interaction decisions made early in the system design.
Deterministic system architecture
- Task scheduling, priorities and timing defined at architecture level
- Interrupt handling and resource access designed to avoid race conditions
- Hardware timers and synchronisation mechanisms aligned with real-time constraints
Validated under real operating load
- Systems tested under peak load, not nominal conditions
- Timing behavior, latency and resource usage measured and verified
- Stability ensured across edge cases and long-running operation
What defines a reliable real-time system
The system has to meet strict timing constraints, maintain consistent latency and remain stable under load, without timing violations or unpredictable behaviour.
Thread interaction, shared resources and synchronisation are designed to eliminate race conditions, deadlocks and priority inversion.
Worst-case execution times are defined and verified, ensuring that timing constraints are met consistently, not only under nominal load.
System timing is aligned with hardware characteristics, including timers, interrupts and peripheral response, to avoid hidden latency sources.
Use Cases
We design and implement RTOS-based systems for aerospace platforms that require deterministic execution and predictable system behavior.

A real-time operating system (RTOS) is used in systems where tasks must be executed within strict timing constraints and with predictable behaviour. It is required in applications such as industrial control, medical devices and aerospace systems where delays or timing inconsistencies can lead to system failure. RTOS enables precise scheduling and prioritisation of tasks.
RTOS provides structured task management, prioritisation and scheduling, which improves scalability and maintainability of the system. It allows multiple tasks to run concurrently with controlled timing behaviour. In more complex systems, RTOS reduces the risk of timing conflicts and improves system reliability.
RTOS integration involves configuring the kernel, defining task scheduling, implementing interrupt handling and aligning the system with hardware constraints. It also includes integration of device drivers and communication interfaces. Proper integration ensures predictable execution and stable system operation.
RTOS optimisation focuses on efficient task scheduling, minimising latency and reducing context switching overhead. It includes tuning priorities, stack usage and interrupt handling mechanisms. Performance is validated under real workload conditions to ensure timing requirements are met.
Common issues include priority inversion, improper task scheduling, memory mismanagement and unstable interrupt handling. These problems can lead to timing inconsistencies and unpredictable system behaviour. Identifying and resolving them requires deep understanding of both RTOS and hardware interaction.
Yes, existing systems can be migrated to RTOS when complexity, scalability or timing requirements increase. Migration involves restructuring task execution, introducing scheduling mechanisms and ensuring compatibility with existing hardware. A well-designed migration improves system control without disrupting core functionality.
