CMX-MicroNet TCP/IP Stack Ports to Infinetix Ethernet Daughter Card

1/12/2004 - CMX Systems, well-known designer of real-time operating systems and TCP/IP software and Infinetix, a leading embedded solutions design consulting company, announced the availability of the CMX-MicroNet TCP/IP stack ported to the Infinetix Ethernet Daughter Card for the Texas Instruments TMS320VC5416 DSK. CMX-MicroNet is a very small footprint TCP/IP software stack that has been developed to provide Internetworking connectivity tools to designers working with 8-bit processors. The Infinetix Ethernet Daughter card is a compact Ethernet adapter using the CS8900 Ethernet controller. The board conforms to the Texas Instruments TMS320 Daughtercard Specification and can be used with a variety of DSP development boards.

This new collaboration between CMX and Infinetix provides a nearly "off-the-shelf" solution for adding low cost TCP/IP connectivity to a DSP design. TCP/IP has become a mainstream connectivity solution for instrumentation and control, so as DSP based products become more widely used, it is critical to have a low cost, reliable TCP/IP stack for embedded DSP products.

Chuck Behrmann, president and CEO of CMX, said, "We are very pleased that Infinetix has selected CMX-MicroNet as a networking tool for this important development platform. CMX and Infinetix can now offer their mutual DSP customers an unmatched combination of flexibility and ease of use for their networking development."

Bruce Weyrauch, president of Infinetix said, "The collaboration between CMX and Infinetix has provided a great solution to a problem many designers are facing. The implementation of CMX-MicroNet in a TI DSP system is straightforward and reliable."

About CMX-MicroNet
CMX-MicroNet is a scaled down TCP/IP software stack with a total ROM footprint of 3Kb - 20Kb, depending upon configuration, for 8-bit processors or those 16-bit processors that require a single-chip solution with no external memory or DSPís. CMX-MicroNet supports more 8-bit, 16-bit microprocessors, and DSPís than any other existing solution. CMX-MicroNet is currently available, starting at $5,500 for the base system. All CMX software includes complete source code, no royalties on shipped products, and free technical support/updates.

About the Infinetix Ethernet Daughter Card
The Ethernet Daughter Card is a 10-BaseT Ethernet controller and associated interface circuitry placed on a board conforming to the Texas Instruments TMS320 Daughtercard Specification. It contains the Cirrus Logic CS8900 Ethernet Controller, Ethernet connector, and other features that make it a valuable development and evaluation board for starting an Ethernet connected DSP project. The Ethernet Daughter Card is currently available for $195. A demo version of CMX-Micronet developed for the Texas Instruments TMS320VC5416 DSK is available upon request. While this evaluation board is limited to 10 Mbit speeds, the migration to a 100 Mbit design can be readily achieved. Infinetix provides consulting services as required to port the CMX-Micronet product for use with other DSP or microcontroller based applications.
