PX5 RTOS

The smaller, faster, deterministic, safety-certified and secure PX5 RTOS is the best RTOS for the most demanding embedded system development on AMD, GigaDevice, NXP Semiconductors, Renesas, SiFive, STMicroelectronics, and Texas Instruments boards.

A native (non-layered) embedded RTOS implementation of the POSIX thread (pthreads) API and best-in-class RTOS performance, small footprint, functional safety, and cybersecurity deliver many advantages over your competitors.

PX5 NET

PX5 NET

PX5 NET is an embedded TCP/IP stack that revolutionizes deeply embedded IoT applications with advanced real-time TCP/IP networking support as well as enhanced safety, security, and portability for embedded RTOS.

Built on the BSD Sockets API, PX5 NET streamlines development, ensures compatibility and ease of use, safeguards against memory corruption vulnerabilities, and sets a new standard for network packet integrity for embedded devices.

PX5 FILE

PX5 FILE embedded FAT file system delivers an ultra-small footprint—less than 6KB of instruction memory and 2KB of RAM-makes it perfect for memory-constrained devices requiring a file system. It is also a highly reliable file system with optional fault—tolerant operation. PX5 FILE achieves high performance through customizable caching mechanisms, including logical sectors, FAT entries, and directory search entries. Using PX5 FILE is easy as it provides a native implementation of the Linux file system API as well as the industry-standard FAT 12/16/32 formats and long file name support. PX5 FILE is fully integrated with the RTOS.

PX5 MODULES

PX5 MODULE technology enables the dynamic loading and execution of separately compiled C application code called modules. Memory isolation for each module is accomplished via the microprocessor (MPU) or memory management unit (MMU), which prevents unauthorized access during module execution. PX5 MODULES is fully integrated with the RTOS, allowing nearly full access to the POSIX pthread APIs as well as API extensions. PX5 Modules are ideal for embedded systems requiring lightweight partial firmware updates and isolation of application code execution.

What is RTOS?

Learn how real-time operating systems (RTOS) provide a platform for embedded software developers to achieve multithreading and concurrency in resource-constrained embedded environments. An embedded RTOS enables developers to focus on application logic rather than processor resources.

Intro to RTOS

Safety-certified RTOS

SGS-TUV Saar pre-certifies that PX5 RTOS complies with IEC-61508 SIL 4 (electronic), IEC 62304 Class C (medical), ISO 26262 ASIL D (automotive), and EN 50128 (rail) functional safety standards. PX5 RTOS is suitable for developing safety-critical software to the highest integrity levels (SIL 4). Learn more about our PX5 RTOS.
