Virtuoso Synchro /VSP
by Eonic Systems

Software Overview

Virtuoso Synchro is a system-level development environment for the specification, simulation, 
emulation, and implementation of synchronous multi-rate DSP applications on multi-processor target 
systems. Application areas: speech, audio, radar, image, video processing, telecommunication 
systems. The different tools allow for target independent descriptions of the application and 
generate an optimal synchronous executable program. As the generated schedule is application 
specific and as no run-time kernel is needed, this minimizes the input-to-output delay and the 
memory requirements. Heterogeneous target hardware is supported. All tools interact with two 
central databases, one to describe the application and one to describe the target hardware. 
Virtuoso Synchro is the commercial development, based on the GRAPE-II research project from the 
ESAT department from the Katholieke Universiteit Leuven, Belgium Specification tool.

Features and Benefits

•	Implicit Virtual Single Processor programming model
•	Optimal communication code inserted automatically
•	Code generation for synchronous dataflow applications
•	No kernel overhead, minimum input-to-output delay
•	System generation: resource estimation, automatic processor mapping, automatic schedule 
generation, code generation

Processor and System Requirements

•	Devices supported: TMS320C4x. A port to the TMS320C80 is undertaken under the TI Elite Program.
•	Software category: Rapid prototyping and application development environment for DSPs and other 
processors
•	Host platform: PC (MS-Windows), Sun (Solaris 1, Solaris 2), and others

Availability

Board-specific support is available in beta-release for the TMS320C40. Virtuoso Synchro is 
available under MS-Windows 3.1 and Solaris.

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.
