Jacksonville, FL - June 8, 2010 - CMX Systems, well-known designer of real-time operating systems, TCP/IP stacks, Flash File Systems and USB software announces that its widely deployed CMX-RTX™ real time operating system, small footprint CMX-MicroNet™ TCP/IP stack and full featured CMX-TCP/IP™ stack are now available for Renesas’ RX600 Series microcontrollers. CMX-USB™ support will be available in the future.

CMX-RTX is a truly preemptive, multi-tasking RTOS supporting a wide variety of 8-, 16-, 32-bit microcomputers, microprocessors, and DSP’s. CMX-RTX offers one of the smallest footprints, fastest context switching times, and the lowest interrupt latency times available on the market today. RTOS functionality provided in CMX-RTX includes: task management, message management, queue management, system management, event management, memory management, resource management, semaphore management and timer management.

CMX-MicroNet is a TCP/IP stack specially crafted to work with virtually all processors and features an extremely small Flash requirement ranging from 5K to 28K and very minimal RAM requirements of about 500 bytes plus buffers for packets. The base CMX-MicroNet software package includes UDP, TCP, IP, Modem, SLIP, ICMP Echo, IGMP, and Virtual File system. Add-On Options available are: SSL/TLS, HTTP Web Server, DNS Client, FTP, SMTP, SNMP, DHCP Client, TFTP Client, SNTP, Fragmentation, POP3, PPP, CHAP, Telnet, Ethernet (ARP, BOOTP) and Wireless.

CMX-TCP/IP is a full-featured, 100% RFC compliant, TCP/IP stack targeted at 16- and 32-bit processors and provides virtually all of the protocols, link layers, interfaces, and device drivers required for most networking applications. The basic CMX TCP/IP stack provides: UDP, TCP, IP, ICMP, IGMP, DNS, ARP, SLIP, Ethernet, an RTOS porting layer, a Standard BSD socket interface and a High Performance Socket Interface. Add on options include: DHCP, IMAP4, FTP, NAT, POP3, PPP, PPPoE, SMTP, SNMP, Telnet Server, TFTP/BOOTP, Web Client ,Web Server, SSL/TLS and Wireless.

CMX also offers a variety of Flash File Systems, including; CMX-FFS-FAT™, a FAT 12/16/32 compatible file system supporting standard media; CMX-FFS-SAFE-FAT™, a FAT compatible file system with Failsafe; CMX-FFS-THIN™, a scalable, reduced footprint FAT file system designed for integration with 8-bit or 16-bit embedded processors with limited resources; CMX-FFS™, a 100% Failsafe flash file system and CMX-FFS-TINY™, a limited resource failsafe file system available in configurations for RAM, Small Sector Byte Writeable Flash, Atmel DataFlash and ST Serial Flash for Data.

All CMX TCP/IP stacks, USB stacks and file systems can operate with or without an RTOS.

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, USB stacks and the CANopen stack for a wide variety of 8-bit, 16-bit, and 32-bit microcomputers, microprocessors, and digital signal processors. The company’s RTOSes support more than 50 processor families and over 30 C-compiler vendors. CMX also offers the tiny CMX-MicroNet, which is a unique TCP/IP stack that is targeted for 8-, 16-, 32-bit and DSP processors with limited ROM and/or RAM, and CMX TCP/IP, a full-featured TCP/IP stack designed for 16-, 32-bit and DSP processors. CMX additionally offers five different Flash File Systems to best meet the memory management needs of embedded developers. CMX-USB is offered for designers wishing to add USB connectivity to their products. For more information, please visit CMX Systems’ website at http://www.cmx.com.
