Jacksonville, FL – April 4, 2006 – CMX Systems, well-known designer of real-time operating systems, TCP/IP, Flash File System, USB and CANopen software, announced today the availability of the popular CMX-RTX RTOS and the tiny CMX-MicroNet TCP/IP stack for the Freescale MCF5223x family of ColdFire processors. The newly introduced MCF5223x series of processors enable embedded design engineers to take advantage of lower-cost 32-bit processing and realize fast, re-programmable embedded system designs using off-the-shelf microcontrollers.

Chuck Behrmann, president and CEO of CMX, said, “We are very pleased to offer embedded designers small and fast embedded software supporting this new and exciting processor series. We feel that this combination of Freescale processors and CMX software provides developers with an elegant and cost-efficient solution for their designs.”

Jeff Bock, Product Marketing Manager for Freescale’s 16/32 bit Consumer & Industrial Operation said, “Embedded software such as the CMX-RTX RTOS and the CMX-MicroNet TCP/IP stack are an excellent demonstration of how well our MCF5223x technology works with leading-edge embedded software systems. The highly efficient MCF5223x derivatives with onboard FEC, used in conjunction with the extremely small and fast CMX-MicroNet, provides significant benefits to the final consumer using the Internet.”

CMX-RTX is a truly preemptive, multi-tasking RTOS supporting a wide variety of 8-, 16-, 32- and 64-bit microcomputers, microprocessors, and DSP's. This "lean and mean" RTOS offers the smallest footprint, the fastest context switching times, and the lowest interrupt latency times available on the market today.

CMX-MicroNet is a TCP/IP stack specially crafted to work with virtually all 8- and 16-bit processors and those 32-bit processors and DSP’s with limited memory resources. With an extremely small ROM requirement ranging from 3.5K to 20K (depending on configuration and processor), this networking tool resides and runs directly on the processor with no gateway required.

Price and Availability

Pricing for CMX-RTX for the MCF5223x series of processors starts at $4,000 and is available immediately. Pricing for CMX-MicroNet for the MCF5223x series of processors starts at $5,500 and is available immediately. All CMX software is provided with full source code, no royalties on shipped products, and free technical support and software updates.

About CMX Systems, Inc.:

Since its inception in 1990, CMX Systems has focused on providing its customers with all of the tools needed to program their embedded applications. The company's core business is to develop and support real-time, multi-tasking operating systems (RTOS), TCP/IP stacks, Flash File Systems, and the CANopen protocol for a wide variety of 8-bit, 16-bit, and 32-bit microcomputers, microprocessors, and digital signal processors. The company's CMX-RTX, CMX-RTXS, and CMX-Tiny+ real-time multi-tasking operating systems support more than 50 processor families and over 30 C-compiler vendors. CMX also develops and supports products that enhance the user's ability to create, test and debug application code, including CMXKAware^TM, CMXBug^TM, and CMXTracker^TM. CMX-TCP/IP^TM, a full-featured TCP/IP stack for 16- and 32-bit processors, also is sold by the company. CMX also offers the tiny CMX-MicroNet, which is a unique TCP/IP stack that is targeted for 8-bit and 16-bit processor target platforms. CMX additionally offers three different Flash File Systems to best meet the memory management needs of embedded developers. CMX also manufactures the CMX-CANopen protocol stack for those developers requiring CANopen functionality. In addition to developing RTOSes, debugging tools, flash file systems, and networking protocols, CMX also distributes a wide variety of C tools, including compilers, assemblers, linkers, librarians, simulators and ROM debuggers from many well-known manufacturers.
