 TCP/IP Products
smxNS
smxNS offers a clean, modular design that enables embedded developers to easily add networking capabilities to their real-time embedded systems. It is ROMable and reentrant to ensure compatibility with multitasking operating systems. It can be easily ported to a variety of processors and RTOSs. We ship it ported to ARM, ColdFire, and x86 for SMX.
Because code and data space are at a premium in small embedded systems, smxNS can be configured to use only those clients/servers, protocols, device drivers, and link layers needed by an application. The basic TCP/IP protocol requires only about 25K bytes on most processors. smxNS provides a choice of device drivers that provide support for most popular embedded network controllers, including 100Mb/s Ethernet devices. smxNS supports standard BSD sockets as well as a simpler interface called Dynamic Protocol Interface (DPI).
The basic package includes: TCP/IP, UDP, ARP, RARP, BOOTP, DHCP c, DNS c, ICMP, SLIP, Telnet s, and TFTP. Available at additional cost are: DHCP s, FTP, IGMP, NAT, POP3, PPP, PPPoE, SMTP, SNMPv2, SNMPv3, and Web Server.
smxNS is a good choice for small embedded systems requiring simple networking features, but for which small size and high performance are necessities.
Additional drivers are being developed—contact us for the latest information.

History of smxNS
The smxNS TCP/IP stack is based upon USNet, which was first shipped in 1993 and has been used in over 1500 products. It was developed by the former U.S. Software, and was taken over by Micro Digital in 2003. Micro Digital provides worldwide sales and support for USNet. We have ported it to SMX and we are currently adding new drivers and improvements to extend the life of this small, efficient TCP/IP stack. |
