Virtuoso User Manual - ClassicCMP

The history of Virtuoso
are dedicated to handling interrupts, one level consists of light context tasks
(called the nanokernel processes) and the highest level is the preemptive
priority driven C task level. This level has a rich set of semantics, is independent
of the network topology and hence is fully scalable.
Despite providing these rich features, Virtuoso is still one of the smallest
and fastest real-time operating systems available.
The latest addition to the family is Virtuoso Synchro, an application generator
for synchronous dataflow applications. It supports the specification, simulation,
emulation and implementation of mono- and multi-rate DSP
applications on multi-processor targets, using a graphical user interface. The
generated code runs with minimum of input-to-output delays and memory
requirements, and can be used where even the smallest overhead from the
kernel would be unacceptable
Virtuoso is complemented by a range of support tools and libraries that
make Virtuoso a complete programming environment, designed to meet the
needs of the developer in a wide range of applications. What Virtuoso delivers
today is the potential to combine the incremental processing from a single
processor to over a 1000 multi-processor network while meeting hard
real-time constraints.
We look forward to receiving your comments, opinions and suggestions
which might help us in the evolution of Virtuoso. As Virtuoso comes with 12
months support and upgrades, do not hesitate to contact us. It could save
you a lot of time and it could start a long lasting relationship.
