Jacksonville, FL - May 8, 2009 - 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™ RTOS is now available for several new Atmel ARM9 processors including the AT91SAM9G20, AT91SAM9RL64 and the AT91SAM9XE Series. The CMX-TCP/IP™ stack is available for the AT91SAM9G20 and the AT91SAM9XE. CMX-USB™ is now available for the AT91SAM9RL64 and AT91SAM9G20. CMX-FFS™ file systems are available for all 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.

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.

CMX-USB™ is a suite of modular USB Host, Device and OTG software providing a “one stop” solution for designs requiring USB connectivity. All CMX-USB versions provide support for HID, Mass Storage, CDC Class drivers and a Bootloader. The CMX-USB Host is available with Add On options including; Audio Class, MIDI Class, OBEX Class, Hub Class and FTDI driver. The CMX-USB device stack offers MTP Class support, RNDIS, Reliable File Interface for storage devices and Embedded Pipe for interfacing a USB device with a host application.

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.
