QuantumRT
Features and Architecture
Precision with QuantumRT
QuantumRT is an advanced pre-emptive, priority-based Real-Time Kernel optimized for Precise Scheduling, deterministic execution, and energy efficiency. It maximizes CPU efficiency, ensuring ultra-low latency and reliable real-time execution—making it ideal for energy-sensitive and high-precision applications.
Ultra-Precise Scheduling
QuantumRT’s Precise Scheduling optimizes CPU efficiency through dynamic scheduling while ensuring precise timing control.
Ultra-Low Latency
QuantumRT’s ultra-low latency utilizes precise scheduling to minimize response times, ensuring real-time execution with minimal delays.
Ultra-Low Power
QuantumRT’s power efficiency minimizes total power consumption, extending battery life in embedded applications.
Scheduling
Beyond Tick-Based Scheduling: Precise Scheduling
QuantumRT implements Precise Scheduling, an advanced approach that dynamically adjusts execution timing. Unlike Tick-Based Scheduling, timer interrupts are only generated when a scheduled event occurs.
For compatibility QuantumRT provides API for querying the traditional tick count.
Tick-Based Scheduling*
* QuantumRT does not support Tick-Based Scheduling and exclusively uses Precise Scheduling.
Precise Scheduling
Kernel Services
Semaphore
Synchronization and signaling.
Mutex
Guarding shared resources.
Message Queue
Thread-safe inter-thread communication.
Software Timer
Timeout handling and event scheduling.
System Call Extension
Custom system calls, such as hardware access.
QuantumRT provides essential services for real-time execution, including synchronization, communication, and time management.
POSIX Compliance
POSIX Native Kernel
QuantumRT implements subset of POSIX.1-2024. See the POSIX compliance matrix.
This enables direct reuse of Linux-style application code in embedded environments without the overhead of a full operating system.
Memory Protection*
QuantumRT’s Memory Protection enforces strict access control over system resources, isolating threads and safeguarding the kernel.
Stack Isolation
Prevents threads accessing each other's memory.
Kernel Isolation
Safeguards kernel memory by restricting direct thread access.
Peripheral Access Control
Limits which threads can access the hardware.
RAM Protection
Restricts unprivileged access to RAM.
* Optional feature – Available for systems requiring memory isolation.
