Company Profile



CMX: Embedded suite for Infineon XMC4000 family

CMX Systems now offers its CMX-RTX RTOS, two TCP/IP stacks and five Flash File Systems for the Infineon XMC4000 family of microcontrollers based on the ARM Cortex-M4 processor. Support is provided for compiler tool chains including IAR and Keil. CMX also plans to announce USB support in the near future.

CMX-RTX is a truly preemptive, multi-tasking RTOS offering one of the smallest footprints, fastest context switching and lowest interrupt latency times available on the market today. RTOS functionality provided in CMX-RTX includes: task, message, queue, system, event, memory, resource, semaphore and timer management. CMX-RTX includes an intuitive Windows GUI that simplifies RTOS configuration.

CMX-MicroNet is a TCP/IP stack specially crafted to work with virtually all processors and features an extremely small Flash requirement and 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 Server, SSL/TLS and Wireless.              
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 Host and Device stacks offer support for HID, Mass Storage, CDC, Audio, Printer, MIDI, MTP, ECM, RNDIS Classes and Bootloader. The CMX-USB Host is available with Add-On options including OBEX Class, Ethernet Emulation Class and FTDI driver. The CMX-USB device stack also offers Personal Healthcare Class support and Pictbridge for MTP Class.

CMX 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 protection against unexpected resets; CMX-FFS-THIN, a scalable, reduced footprint FAT file system designed for processors with limited resources; CMX-FFS, a 100% Failsafe flash file system and CMX-FFS-TINY, a limited resource failsafe file system for Serial Flash, DataFlash and Small Sector Byte Writeable flash. CMX TCP/IP stacks, USB stacks and file systems can operate with or without an RTOS.
