PLUS
The Nucleus PLUS kernel provides efficient,
high performance task management, inter-task
communication, inter-task synchronization,
memory management, and component query
features. Optimizations in system clock,
interrupt and compiler register usage are
only part of the advanced features provided
by Nucleus PLUS. The scaleable nature of
Nucleus PLUS tunes size and function,
providing the necessary OS support to
build complex designs all while keeping the
interrupt latency to a few microseconds.
Nucleus PLUS is renowned for its broad
range of facilities for building efficient
embedded systems.
Porting Nucleus PLUS to new processor
families is straightforward and reliable, since
it is written primarily in ANSI C. To port
Nucleus PLUS we need only modify the
system initialization, task management, and
timer control modules. The portability of
Nucleus PLUS benefits you by allowing
processors to be changed without concern
for the new architecture. Further, it allows
you to execute your application easily on
new hardware (board) designs.
For AT91 devices, we also offer services for
networking and Internet protocols, a file
system, USB support, services for World
Wide Web access, and a data encryption
solution. Our complete family of Nucleus
embedded software is designed around a
solid micro-kernel architecture; one that
maximizes performance, robustness and
scalability. All products in the Nucleus RTOS
family come with our “source code, no
royalty” model.
