CMX TCP/IP Stack: CMX-MicroNet

TCP/IP for 8-bit, 16-bit and 32-bit Embedded Processors

CMX-MicroNet has been developed by the company that is famous for providing complete, elegant solutions to the embedded community – CMX! CMX’s developers have the expertise and hands-on experience to satisfy the most stringent real time demands that the 8-, 16-, and 32-bit community deals with every day. When we set about the task of creating the first true TCP/IP stack for these popular processors, we knew that it had to have:

Only Industry Standard Protocols. Of what benefit are closed, proprietary protocols that constrain and confuse your development team? CMX-MicroNet offers only industry standard protocols running right on your target processor and we provide full source code with every sale!

Use your Current Processor. Why should you have to upgrade your current processor, or, worst yet, add another processor just for TCP/IP? Those hardware costs can really add up! CMX-MicroNet allows you to work with your current design and still implement the networking connectivity you need.

An Affordable Pricing Structure.
CMX-MicroNet offers a low, one-time fee and no royalties on deployed products. And you get the entire source code for free with every purchase!

High performance TCP/IP implementation

CMX-TCP/IP is a portable high performance TCP/IP implementation for embedded systems. Memory usage is localised and deterministic. It uses the CMX-RTX RTOS signaling mechanisms to provide a true multitasking reentrant stack. CMX-TCP/IP can also be run without an RTOS and all of the code is written to make it easy to switch between modes without extensive source-code changes.

Most network protocols and applications are available, from BOOTP all the way up to HTTP. There are also test applications, such as a benchmark server or a ping tester, as well as a few others. A consistent command shell debug facility for all modules allows for the interactive execution of debugging commands and setting debug levels of particular modules via a serial port or Telnet connection which can be a real plus when bringing up new Ethernet hardware, etc. At production time, you may simply link with the non-debug version of the libraries for maximum memory efficiency.

Supported Protocols

  • IP, ICMP/Raw IP, TCP, UDP, ARP, SNTP, DNS name resolution.
  • TCP/IP SNMP MIB can be included, to provide a plethora of IP performance data.
  • RFC compliant TCP support both Standard BSD Socket interface as well as High performance proprietary Socket interface
  • Standard IBM-PC compatible drivers available for keyboard, VGA, PCI, serial port, etc.
  • Includes a VFS (Virtual File System) with huffman tree compression for read-only data such as web pages, for maximum memory efficiency.
  • Specific Processor and Compiler port
  • Full Source code
  • No Royalties on Shipped Products
  • Documentation, sample test programs
  • Many Ethernet Drivers for a variety of chips including 91c96, 91c111, cs8900a, etc.
  • Free Technical Support

Additional Add-On Options:

  • BOOTP, TFTP – Bootstrap Protocol, Trivial File Transfer(Client/Server)
  • DHCP – Dynamic Host Configuration Protocol Server (Client/Server)
  • Flash File System with support for Compact Flash, MMC, RAM disk, etc.
  • FTP – File Transfer Protocol (Client/Server)
  • IMAP4 – Internet Messaging Access Protocol, Version 4
  • NAT – Network Address Translation
  • POP3 Client – Post Office Protocol
  • PPP, SLIP – Point to Point Protocol, Serial Line Interface Protocol
  • PPPoE – PPP over Ethernet

CMX TCP/IP Stack: CMX-INet-Plus

CMX-INet-Plus is an RFC compliant TCP/IP stack offering extensive security protocols as well as IPv4 and IPv6 support for projects that require IPv4 now with an upgrade path to IPv6 in the future or IPv6 now. CMX-INet-Plus will work with or without an RTOS and offers an extensive variety of networking and security Add-On options giving the designer the ability to implement only those options required for their embedded application.

CMX-INet-Plus allows for mixed IPv4 and IPv6 traffic and supports Multicast and Neighbor discovery, delayed acknowledgements and zero data copy for maximum performance. Also includes a Virtual File System for read only data such as web pages.
