The ARC MQX RTOS solution includes full source code and offers many comprehensive features that support reliability, deterministic performance, reconfiguration, and multiprocessing. The scalable design allows MQX users to pick the components and features they require from MQX and prevents unused features from being included in the RTOS memory footprint. With code size as low as 3.8 KB, the MQX RTOS solution is small enough to replace a home-grown scheduler while still providing a much more comprehensive feature set.
Size-critical applications can use the MetaWare Automatic Overlay Manager (AOM), even in a multi-tasking environment, since MQX has specific support for AOM built-in.
With MQX's function-level scalability, all API functions outside of the central core are only included in the linked image if they are explicitly called by the application. This, along with dozens of compile-time configuration options (also grouped into sets), gives the application developer maximum control over the memory footprint of MQX.
MQX RTOS is small enough to replace a home-grown scheduler, while still providing a much more comprehensive feature set.
| Architecture | Minimum code size* | Context switch time |
|---|---|---|
| ARC HS Family | 3.8 KB | 105 cycles |
| ARC EM Family | 3.8 KB | 90 cycles |
| ARC 600 Family | 4.0 KB | 115 cycles |
| ARC 700 Family | 4.1 KB | 170 cycles |
*Includes interrupt handler, scheduler, memory manager, micro-kernel, task management, time management, processor and board support package.
All measurements performed on FPGA platforms, each core configured with 256 ICCM and DCCM. Context switch definition: time required to save a current tasks context and restore context of highest priority task ready to run.
The ARC MQX RTOS is available for the full range of MIPS ARC 600, ARC 700, ARC EM, and ARC HS processors. End-users can easily configure the MQX RTOS to support any configuration.
Board Support Packages (BSPs) are available for the ARC EM Starter Kit, ARC Software Development Platform and the HAPS Prototyping System. MQX also runs on the ARC nSIM Instruction Set Simulator. Users can easily modify MQX RTOS BSPs to support changes in the user's MIPS ARC-based SoC configuration.
MQX Task Aware Debugging (TAD) for MetaWare - Integrated into the MetaWare Debugger, TAD provides intimate details of the embedded system, giving visibility into MQX's data structures via easy-to-understand displays. You can view task summaries, the state of individual tasks, and details on queues, messages, semaphores, memory and memory partitions; full access to all MQX data through easy-to-understand displays!
Highlights & Key Features
- Highly optimized for ARC subsystems and configurable ARC cores
- Compact (3.8 KB), configurable and scalable microkernel architecture
- Reliable operation, fast real-time response for deeply embedded designs
- Includes full source to enable full user configuration control and optimization
- Powerful MQX Host Tools included for debugging, performance analysis and prototyping
- Up and running right out of the box with MetaWare Development Toolkit
- MetaWare MQX-aware debugging with MetaWare Development Toolkit
