PX5 RTOS Is The Fastest
Boosting device performance and cutting power usage
The PX5 RTOS is the fastest in the 2024 RTOS Performance Report issued by the Beningo Embedded Group. Based on the open-source ThreadMetric RTOS performance tests, the PX5 RTOS showed superior performance over three widely used RTOS: ThreadX, FreeRTOS, and Zephyr. Here are some of the report highlights:
- PX5 RTOS is up to 22% faster than ThreadX
- PX5 RTOS is up to 4.4 times faster than FreeRTOS
- PX5 RTOS is up to 7.2 times faster than Zephyr
PX5 RTOS Is Even Faster with IAR
The 2024 RTOS Performance Report benchmarks were based on the GCC compiler.
The PX5 RTOS — the fastest RTOS — is another 30% faster using the advanced IAR compiler!
- 22% faster Preemptive Scheduling with IAR!
- 34% faster Memory Allocation with IAR!
- 38% faster Message Processing with IAR!
- 22% faster Thread Synchronization with IAR!
Why Is Performance Important?
According to most embedded developer surveys, RTOS real-time performance is at or near the top of their priorities. Some of the reasons for this include:
- Faster RTOS enables faster device response
- Faster RTOS executes fewer instructions, reducing power consumption
- Faster RTOS frees more cycles for the application to use
- Faster RTOS can reduce BOM costs
- Faster RTOS improves development
- Real-time performance is all-important-by its very definition, if your device doesn’t meet its real-time requirements, it fails. In safety-critical applications, such a failure can be catastrophic. The superior performance of PX5 RTOS provides the best foundation to meet the most demanding real-time requirements.
- PX5 RTOS requires fewer cycles, which implicitly helps meet the needs of applications with demanding power requirements, perhaps even making some of them feasible. In addition, the cycles not used by PX5 RTOS are now available for the application.
- PX5 RTOS allows you to use a less expensive processor since it requires fewer cycles. How much of a savings depends on the use case, but simply increasing processing power from 84MHz to 168MHz can add another $1 to your BOM cost. Likely, the slower RTOS is bigger, too, which can further increase BOM cost.
- Development with the PX5 RTOS is more manageable. It helps developers quickly solve their real-time, power, and application processing needs, saving time and schedule. As of 2023, an average 8-person development team costs roughly $6K daily. Using the PX5 RTOS, many development days can be eliminated, significantly reducing the total development cost, especially for larger development teams.
How PX5 RTOS Benefits You
Somewhat summarizing the previous section, here are some of the benefits the PX5 RTOS brings to your development:
- Improved Product Responsiveness
- Reduced Power Consumption
- Reduced Development Schedule
- Reduced Development Cost
- Reduced BOM Cost
- Accelerated Time-To-Market
The industrial-grade PX5 RTOS, a 5th-generation system, offers unmatched performance, safety, and security with a native pthreads API for demanding embedded applications.
