Freescale MQX Real-Time TCP/IP
Communication Suite
The Freescale MQX real-time communication
suite (RTCS) is a fast, efficient and low-
footprint embedded Internet stack that
supports a rich set of standard TCP/IP
protocols. It comes complete with a number of
application layer protocols such as Telnet, FTP,
SNMP v1 and SNMP v2. A number of optional,
pre-integrated protocols and products are also
available from third parties. The scalability of
the Freescale MQX RTCS allows developers
to easily define the feature set needed to
accommodate a variety of ROM and RAM
memory budgets.
Certifiable to Medical and
Aerospace Standards
Even for applications that do not require formal
certification, the robustness of MQX provides
a trusted platform that has been proven
in thousands of time-critical, sophisticated
applications. For designs that do have a
formal certification process to follow, MQX
is an excellent choice. Past licensees have
certified MQX-based applications to medical
specifications (CFR 820.30 Part 21, IEC
60601-1) and the aerospace requirements
listed under DO-178b. Safety critical
applications based on MQX include eye
surgery equipment, drug injection equipment,
radiation dose monitoring equipment, aircraft
braking systems and aircraft navigation
equipment.
