“…Recently, some research has focussed on abstracting communication for the purpose of specification and possibly automatic generation of communication implementations from such higher-level specifications [7,8,10,12]. Although they are the motivation for our intermediate processor model, these approaches focus on abstracting communication and don't provide as high abstractions for the computational aspects.…”

Raising the level of abstraction is widely seen as the solution for closing the productivity gap in system design. They key for the success of this approach, however, are well-defined abstraction levels and models. In this paper, we present such system level semantics to cover the system design process. We define properties and features of each model. Formalization of the flow enables design automation for synthesis and verification to achieve the required productivity gains. Through customization, the semantics allow creation of specific design methodologies. We applied the concepts to system languages SystemC and SpecC. Using the example of a JPEG encoder, we will demonstrate the feasibility and effectiveness of the approach.

“…The SLDLs, such as SystemC and SpecC, model the communication aspects in the message level, following the taxonomy proposed in [2]. In this level the structure of the communication still must be modeled as interconnection among the modules of the system.…”

The electronic devices market demands a larger amount of functionality integrated into a single product. To address this demand, the industry migrated to solutions based on processors, increasing the software role in the systems. However, processor-based solutions raises the design complexity due to the complexity of Hardware-dependent Software (HdS). To cope with this complexity, the virtual platforms approach is applied, in which the whole system is modeled in order to reduce the design time. Nowadays, much of this work is manually performed, synthesizing all structures and behavior required in a system level design language (SLDL). However, with the increasing systems complexity, it is becoming impractical to continue performing this synthesis manually. In the last decade, several studies have addressed the synthesis of software components from descriptions in SLDLs and recently in the Unified Modeling Language (UML). Although significant automation has been obtained, there are limitations in the abstraction achieved. In order to raise the abstraction of the description, the UML-ESL profile was proposed to abstract the communication structure, with a synthesis technique for communication between software and hardware interfaces. This work presents a technique to synthesize the multitasking support and the communication between software components of the system from a description in UML-ESL for virtual platform simulation. The results obtained showed up to 60% decrease in the amount of code manually written.

Memory represents a major bottleneck in embedded systems. For multimedia applications bulky of data in these embedded systems require shared memory. But the integration of this kind of memory implies some architectural modifications and code transformations. And no automatic tool exists allowing designers to integrate shared memory in the SoC design flow. In this work, we present a systematic approach for the design of shared memory architectures for application-specific multiprocessor systems-on-chip. This work focuses on the code-transformations related to the integration of a shared memory.
