Virtuoso Classico /VSP 
by Eonic Systems

Software Overview

Virtuoso Classico is a high-performance real-time operating system with integrated microkernel and 
nanokernel for parallel DSPs and high-end processors. It provides fully-distributed semantics for 
transparent parallel programming. Hard real-time characteristics are guaranteed across processor 
boundaries by the use of a priority based, packetizing, and multiplexing routing layer. The 
nanokernel processes in particular provides sub-microsecond context switch times.
Virtuoso Classico offers kernel services on a C-level Microkernel API and on the nanokernel level. 
These services handle tasks, interrupts, semaphores, mailboxes, queues, resources, messages, and 
distributed memcopy(). In addition, Classico includes a complete communication layer and various 
drivers: timers, host interface drivers, DMA-based raw protocol comm port drivers and network 
drivers. Most services are available in blocking versions, in non-blocking and timed-out versions. 
Classico contains all functionality from Virtuoso Micro and most of Virtuoso Nano.
A subset, called the P-kit, contains all parallel-processing services offering a smaller codesize 
of about 25% and using a non-preemptive scheduler. The P-kit subset is especially aimed at OEM 
customers.

Company Background and Contact Information

Eonic Systems grew out of Intelligent Systems International which was founded in 1989. It quickly 
specialized in the development of high-performance programming tools for single- and 
multi-processor targets used in hard real-time applications: real-time OSs, libraries, rapid 
prototyping, and fast application development tools. Concentrating on DSPs, Eonic Systems is a core 
member of the DSP Valley Consortium, located in Leuven, Belgium.
