“…If one of the developed C applications needs to run on several cores, the user has to split the code in several tasks manually. Magalhaes et al [9] extended the Hellfire Framework with web-based interface to generate the simulation platform and add NoC support to the simulator.…”

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.

The design of high-performance Multiprocessor Systems-on-Chip (MPSoCs) has proven to be an attractive challenge in embedded systems design automation. However, the complexity of such designs associated with short timeto-market constraints impose serious limitations on the exploration of different configurations and scenarios on the design space exploration. The use of virtual platforms may decrease the time-to-market of these architectures while providing the means to exploit, debug and verify architectures with different features. In this paper, we present the webbased Simplify framework, an interactive approach for MPSoC exploration using an instruction-accurate Open Virtual Platform (OVP). The framework provides an environment to define both software and hardware properties in an intuitive way, and allows designers to validate the functionality as well as the behavior of the modeled architectures at highabstraction levels. Based on the simulation reports generated from the framework, designers can perform further design modifications and optimizations, and re-validate the whole system in an efficient way, allowing increased design space exploration. For the evaluation of the proposed approach, a set of benchmark applications extracted from MiBench has been used. They run on five different processors (MIPS32, ARM7, OpenRISC (OR1K), PowerPC32 and MicroBlaze) on both mono and multiprocessor architectures and the experiments show considerable simulation speed-ups to obtain application profiling at instruction-level compared to existing approaches based on tracing.
