Abstract-The design and test of Multi-Processor Systemon-Chips (MPSoCs) and development of distributed applications and/or operating systems executed on those hardware platforms is one of the biggest challenges in today's system design. This applies in particular when short time-tomarket constraints impose serious limitations on the exploration of the design space. The use of virtual platforms can help in decreasing the development and test cycles. In this paper, we present a cloud-based environment supporting the user in designing heterogeneous MPSoCs and developing distributed applications. Therefore, the design environment generates virtual platforms automatically allowing fast prototyping cycles especially in the software development process, and exports the design to a hardware flow synthesizing compatible FPGA designs. The extension of the peripheral models with debug information supports the developer during test and debug cycles and avoids the need of adding special debug codes in the application. This improves the readability, portability and maintainability of produced software. Additionally, this paper presents the benefits of using cloud-based design environments in engineers' trainings and educations. Therefore, the framework supports testing the system including complex software stacks with prerecorded data or testbenches.

“…In [12], the authors describe the benefits of examining the safe functionality of complex systems early in the design phase. Virtualization technologies such as [13], [14], [15] provide a mechanism to test and develop applications on single nodes. The work described in this paper focuses on a framework to test and evaluate applications under varying network conditions distributed across a cluster of these nodes.…”

Mobile clouds such as network-connected vehicles and satellite clusters are an emerging class of systems that are extensions to traditional real-time embedded systems: they provide long-term mission platforms made up of dynamic clusters of heterogeneous hardware nodes communicating over ad hoc wireless networks. Besides the inherent complexities entailed by a distributed architecture, developing software and testing these systems is difficult due to a number of other reasons, including the mobile nature of such systems, which can require a model of the physical dynamics of the system for accurate simulation and testing. This paper describes a rapid development and testing framework for a distributed satellite system. Our solutions include a modeling language for configuring and specifying an application's interaction with the middleware layer, a physics simulator integrated with hardware in the loop to provide the system's physical dynamics and the integration of a network traffic tool to dynamically vary the network bandwidth based on the physical dynamics.
