Industrial Grade Alternative to Eclipse NetX Duo

x net symbol

Reimagined by Bill Lamie, RTOSX NET is the Industrial Grade alternative to Eclipse NetX Duo. It was originally derived from the Eclipse NetX Duo source code, refactored and infused with some of the advanced technology of the PX5 NET TCP/IP stack. It is 100% API compatible with existing NETX DUO applications and is one of the smallest and most efficient network stacks, ideal for memory-constrained devices:

  • RTOSX NET requires less than 9KB of flash memory
  • RTOSX NET requires less than 5KB of RAM

RTOSX NET delivers ultra-high performance through its zero-copy packet send/receive API.

RTOSX NET supports most popular Internet protocols, including cloud, security, and network time protocols. Please see the diagram below for the complete offering.

RTOSX NET also enables best-in-class safety and security for your embedded applications.

  • The entire RTOSX NET code base is tested with 100% C statement and branch decision coverage for every release.
  • RTOSX NET offers optional run-time packet pools overflow and integrity checking.
  • The RTOSX NET offers Pointer/Data Verification (PDV) technology for unprecedented run-time function pointer, system object, buffer, and stack verification. This advanced technology is from the PX5 RTOS.
  • Central error handling technology from PX5 RTOS.
  • The RTOS is certified to the industry functional safety standards IEC 61508 SIL 4 (electronic), IEC 62304 Class C (medical), ISO 26262 ASIL D (automotive), and EN 50128 SW-SIL 4 (rail).

Small Footprint

RTOSX NET is one of the smallest embedded TCP/IP stacks, with a minimal instruction area footprint of 9KB and a minimal RAM requirement of less than 5KB. RTOSX NET automatically scales based on the application’s usage.

Fast Performance

RTOSX NET is extremely fast and efficient because of its zero-copy API, resulting in near wire-speed performance on most platforms.

Safety-certified TCP/IP

SIMPLE, ONE SOURCE FILE

RTOSX NET is comprised of one source file: rtosx_net.c. Drop this file into any RTOSX C project, and it will be ready to run. There are no complicated projects or linker control file changes.

RTOSX NET is easy to install and use, taking only a few minutes. Use the processor-to-tool binding layer examples as a starting point.

RTOSX NET is 100% API compatible with applications written for NETX DUO.

Advanced Technology

  • Data encapsulation technology assists compilers in generating the smallest, fastest code and reduces namespace collision with the application.
  • Pointer/Data Verification (PDV) technology, a next-generation embedded RTOS technology, enables unprecedented verification of run-time function pointers, linked lists, stacks, and network packets.
  • Central error handling – with optional user enhancement – helps facilitate building more robust applications.

Full Source Code

  • You receive complete source code.
  • The RTOSX NET source code is designed to be easily understood.
  • The RTOSX NET source code is rigorously tested: 100% C statement and branch decision coverage testing for every release.
  • Discover one of the highest quality embedded TCP/IP network stack source code on the market.

Portable Network Stack

RTOSX NET is written in ANSI C, making it highly portable to any processor architecture with C compiler support. It supports popular embedded MCU and MPU architectures, including the ARM Cortex-M, Cortex-R, Cortex-A, and RISC-V architecture families.

IAR, Arm & GCC tool support

As with its processor support, the RTOSX NET supports the most popular embedded development tools, including those from IAR, Arm, and GCC.

Professional tech Support

The embedded RTOS experts on the RTOSX NET support team are always ready to help and promise quick action on every request. Unlike many open-source and commercial network stacks, RTOSX support is available when needed. We are here to help!
