Overview

The Recoding Infrastructure for SystemC (RISC) project addresses the advanced analysis and agressive parallel simulation of embedded system models with hardware and software components. We focus on Transaction Level Models (TLM 1.0 and TLM-2.0) described in the SystemC language and aim for maximum compliance with the IEEE standard 1666. As simulation host platform, the project targets modern multi- and many-core computer architectures, including the Intel® Many Integrated Core (MIC) architecture, such as the Xeon® Phi™ Coprocessor.

Project Overview

A central goal of the project is the efficient analysis and validation of IEEE SystemC design models through high-performance simulation with maximum parallelism for fast and accurate performance analysis and rapid design space exploration.
This project encompasses the detailed study, research and development of
  1. analysis, visualization and transformation tools for high-level SystemC models,
  2. advanced out-of-order parallel simulation algorithms for the SystemC language, and
  3. efficient mapping of parallel threads onto symmetric many-core platforms.

RISC Compiler

At the center of the project is the research and development of analysis, visualization and transformation tools for IEEE SystemC models, including
  • advanced static and dynamic analyzers of SystemC models,
  • a dedicated SystemC compiler for aggressive yet standard-compliant parallel simulation,
  • a parallel simulator with out-of-order execution on many-core platforms,
  • visualization tools for hierarchical connectivity and potential parallelism, and
  • recoding tools for source-to-source transformation of legacy SystemC models.

Open Source Releases

The Recoding Infrastructure for SystemC (RISC) is an open-source framework for static and dynamic analysis and source-to-source transformations of IEEE SystemC models.
RISC is built on top of Accellera SystemC and the Rose compiler.
RISC provides a dedicated SystemC compiler and out-of-order parallel simulator, as well as model visualization and performance tuning tools. In addition, the RISC data structures offer programming access to the Internal Representation (IR) and Segment Graph (SG) of SystemC models via documented APIs.
