Determinism by Design, Not by Luck
Real-time behaviour is a system property, not a firmware feature. Quantova designs RTOS architecture with timing analysis from the first task definition — deadline analysis, worst-case execution time profiling, and jitter measurement on your target hardware.
Core Services
RTOS Architecture Design (Real-Time OS)
Task decomposition, priority assignment, and scheduling analysis — Rate Monotonic and EDF scheduling with formal deadline verification.
Hard Real-Time Control Loops
PID controllers, motor drive loops, and servo control at deterministic cycle rates — tested with hardware-in-the-loop measurement.
Safety-Critical Firmware
IEC 61508 and ISO 26262-aware firmware design practices — diagnostics, safe state management, and watchdog architecture.
WCET Analysis
Worst-case execution time profiling using hardware cycle counters and RTOS trace tools. Timing budget documented per task.

Common Questions
On a Cortex-M4 (for example an STM32F4 at 168MHz), interrupt entry takes 12 cycles with zero-wait-state memory, and typical latency to the first ISR instruction is 12–20 cycles once flash wait states and bus contention are included. We profile your specific configuration and document the achieved latency.
We can implement firmware to be certification-aware. We do not act as a certification authority, but we ensure the firmware engineering process and documentation meet the standard requirements your certifier will review.
