Boston, MA - September 18, 2007– CMX Systems, well-known designer of real-time operating systems, TCP/IP, Flash File System, USB software, provides support for its CMX-RTX RTOS, two TCP/IP stacks, four Flash File Systems and multiple USB stacks for the ColdFire family of processors. CMX software supports virtually all ColdFire processors.

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 the smallest footprint, the 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. CMXKAware provides kernel aware debugging.

CMX-MicroNet is a TCP/IP stack specially crafted to work with virtually all processors and features an extremely small ROM requirement ranging from 5K to 24K (depending on configuration and processor) and very minimal RAM requirements of about 500 bytes plus buffers for packets. The base CMX-MicroNet software package currently includes UDP, TCP, IP, Modem, SLIP, ICMP Echo, IGMP, and Virtual File system. Current Add-On Options available are: HTTP Web Server, DNS Client, FTP, SMTP, SNMP, DHCP Client, TFTP Client, Fragmentation, SNTP, POP3, PPP, CHAP, Ethernet (ARP, BOOTP) and Wireless Ethernet. The CMX-MicroNet stack can work with or without an RTOS.

CMX-TCP/IP is a full-featured, 100% RFC compliant, TCP/IP stack targeted at 16- and 32-bit processors. CMX-TCP/IP provides virtually all of the protocols, link layers, interfaces, and device drivers that are required for most networking connectivity 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 and Wireless Ethernet. The CMX-TCP/IP stack can work with or without an RTOS.

CMX-USB-HostOHCI and CMX-USB-HostEHCI are designed for processors with both integrated USB host controllers and external USB host controllers which conform to the OHCI or EHCI standards. The CMX-USB-Host, OHCI and EHCI, packages are fully compatible with CMX's Host Class drivers for Mass Storage, CDC, HID, and PrinterLite. CMX-USB Host Mass Storage is fully compatible with CMX-FFS-THIN and CMX-FFS-FAT File Systems.

CMX-USB-Host is a highly optimized USB host stack and designed for microcontrollers with integrated USB host controllers with a non standard programming interface (i.e. those that are not OHCI or EHCI compliant). The CMX-USB-Host package is fully compatible with CMX Host Class drivers for Mass Storage, CDC, HID and the PrinterLite. CMX-USB-Host Mass Storage is also compatible with CMX-FFS-THIN and CMX-FFS-FAT File Systems.

CMX-USB-BS is a device stack and is supplied with a HID class implementation for supporting Human Interface Devices such as a keyboard, mouse or joystick. Add-on options include: a Flash Bootloader, a full USB Mass Storage Class with optimized drivers for accessing MMC/SD cards or other devices, a CDC class implementation for supporting standard communications ports and an Embedded Pipe for interfacing a USB device with a host application. The USB Mass Storage implementation is fully compatible with CMX-FFS-THIN and CMX-FFS-FAT File Systems.

CMX-FFS is the 100% Failsafe flash file system for embedded systems developers and includes multiple volumes, Wear-leveling, Directories, Bad Block management, ECC algorithms, Boot sector support, and RAM Drive. Additional drivers for CMX-FFS include CMX-FFS-NOR (NOR Flash Driver), CMX-FFS-NAND (NAND Flash Driver) and CMX-FFS-DF (Atmel DataFlash Driver.)

CMX-FFS-TINY is a limited resource failsafe file system. CMX-FFS-TINY can be purchased in three configurations: CMX-FFS-TINY-BW (for Small Sector Byte Writeable Flash), CMX-FFS-TINY-DF (for Atmel DataFlash) and CMX-FFS-TINY-ST (for ST Serial Flash for Data).

CMX-FFS-FAT is a full-featured file system for embedded systems developers who wish to add devices to their products that require FAT12/16/32 compliant media to be attached to them. CMX-FFS-FAT features includes Long filenames, Multiple Volumes, Media Error handling, Mix of Media, Check Disk and the following Drivers: Compact Flash (True IDE and Memory I/O), MMC/SD (SPI S/W or H/W) and RAM. Additional drivers for CMX-FFS-FAT include CMX-FFS-FAT-FTL (Flash Translation Layer for NAND Devices) and CMX-FFS-FAT-DFML (for Atmel DataFlash).

CMX-FFS-THIN is a scalable, reduced footprint file system designed for integration with 8-bit or 16-bit embedded processors with limited resources and includes FAT 12/16/32, Long file names, Media Error handling and the following Drivers: Compact Flash (True IDE and Memory I/O), MMC/SD (SPI S/W or H/W) and RAM. Additional drivers for CMX-FFS-THIN include CMX-FFS-THIN-FTL (Flash Translation Layer for NAND Devices) and CMX-FFS-THIN-DFML (for Atmel DataFlash).

All CMX products feature full source code, no royalties, and free technical support and updates with every purchase. CMX-RTX and CMX-MicroNet are available from CMX Systems and its distributors. Contact CMX Systems at 904-880-1840 or email
