An SDR implementation is a system decision, in which the selection of both the underlying hardware composition and the software architecture are critical design aspects.
All processing is done using the CM/CLM family of Common Lisp based composition and sound processing software running on top of the Linux operating system.
The demos that resulted from this – Mvula working on a laptop, equipped with not much more than a mic, a keyboard and a piece of composition software – caught the ear of a producer, Steve Brown, and his manager, Kwame Kwaten.
The marriage of computers and music has spawned digital instruments that sound "real," an interface-the musical-instrument digital interface-that's now an industry mainstay, and composition software that helps generate ideas, assemble phrases, and analyze existing works.
Therefore, DXA needs cross-validation for transferring composition results among devices and software modes (Plank, 2005; Scholz et al., 2007 and 2013; Hull et al., 2009; Lösel et al., 2010).
This is chiefly due to the lack of support for specifying component interfaces and software compositions formally.
Moreover, a design based on higher-level abstraction enable a better design space exploration between several hardware and software compositions.
Cyber-physical systems (CPS) refer to novel hardware and software compositions creating smart, autonomously acting devices, enabling efficient end-to-end workflows and new forms of user-machine interaction, in a wide range of application fields.
This paper investigates how software composition and transformation can be applied to domain specific languages used today in modeling and simulation of physical systems.
In particular, service- and thing-based systems pose new challenges for software composition and verification techniques, due to changing requirements, emerging behaviors, uncertainty, and dynamicity.
