VIRTUOSO MODULO
Set of Libraries
by High-Tech Services Partners

Software Overview

VIRTUOSO MODULO is a complementary set of libraries especially designed for floating-point DSP 
applications. They can be used in a sequential standalone mode or in conjunction with the VIRTUOSO 
multi-tasking products. All functions use a consistent naming scheme that facilitates readability 
and portability to processors with different word lengths.

Company Background and Contact Information

HSP is specialized in supplying integrated high-performance parallel-processing systems. The 
company is among the first to use extensively MIMD multi-processor structures to implement 
real-time and/or number-crunching applications, with an emphasis on a system approach. Where 
needed, special hardwares, basic software, and application software are developed on a specific 
basis.
