The manager which manages all the tasks efficiently of the system
under consideration. The knowledge of RTOS is of utmost importance
considering the kind of complexity which goes into wireless embedded
systems. Be it a controlling of whole GSM operations of a city or
managing your PDA or Cell phone, RTOS make things happen for you. One
should have a better understanding of RTOS to build systems which are
reliable. QNX is one of the RTOS which goes into making of successful
MSC-BSC operations of a complex GSM networks and Symbian makes your
PDAs and cell phones complex features. Implementing optimize protocol
stacks in for better performance is only because of more reliable RTOS
which is so much demand. RTOS knowledge today is very important while
designing complex protocol designing and interfacing system
application for wireless embedded systems. Some of the RTOS is as
QNX Neutrino is a microkernel operating system that makes
fault-resilient, field-upgradeable systems much easier to design and
implement. QNX Neutrino also offers unprecedented scalability:
Developers can build their applications once, then distribute them on
a single processor, across a massive cluster of processors, or on an
SMP system - all without special coding. QNX Neutrino represents the
latest generation of QNX OS technology, and is the product of more
than 20 years' experience in the embedded market.
In QNX Neutrino, the OS kernel delivers only essential services, such
as thread scheduling, IPC, and synchronization. All other OS services,
drivers, and applications run as separate processes that communicate
with the kernel via synchronous message passing. This message passing
forms a virtual "software bus" that lets you dynamically plug in or
plug out whatever services are required. Consequently, almost any
module, even a device driver, can be replaced or restarted on the fly.
In most Operating Systems, this would, at the very least, require a
QNX is used in some MSC as the controlling RTOS. Also some network
devices like routers, access points uses QNX as there RTOS.
