The integration opportunities offered by technological and method-ological advancements permit to create heterogeneous systems that provide high levels of parallelism on a single chip, such as FP-GAs hosting a processor core and co-processors. However, in order to optimize the exploitation of this parallelism, it is necessary to improve the architectural(More)
Performance modeling and evaluation of embedded hardware/software systems is important to help the CoDesign process. The hardware/software partitioning needs to be evaluated before synthesizing the solution. This paper presents a co-simulation technique based on the use of an uninterpreted model able to accurately represent the behavior of the whole system.(More)
GAUT is an open source High-Level Synthesis tool. From a bit-accurate C/C++ specification it automatically generates a RTL architecture described in VHDL that can be used by commercial logical synthesis tools like ISE (Xilinx), Quartus (Altera). GAUT also generates TLM and CABA SystemC simulation models for the SocLib virtual prototyping platform.
In this paper we propose an ESL synthesis framework which, from the C code of an application and a description of a generic architecture, automatically explores and generates a complete synthesizable version of a H-MPSoC architecture along with the adapted code application. We developed a Design Space Exploration (DSE) algorithm that merges hardware(More)
Recommended by Markus Rupp Digital signal processing (DSP) applications are nowadays widely used and their complexity is ever growing. The design of dedicated hardware accelerators is thus still needed in system-on-chip and embedded systems. Realistic hardware implementation requires first to convert the floating-point data of the initial specification into(More)
This paper presents an innovative technique to efficiently develop hardware and software code generators. The specification model is first converted into its equivalent data structure. Target programs result from a set of transformation rules applied to the data structure. These rules are written in a textual form named Script. Moreover, transformations for(More)
This article describes TBES, a software end-to-end environment for synthesizing multitask applications on FPGAs. The implementation follows a template-based approach for creating heterogeneous multiprocessor architectures. Heterogeneity stems from the use of general-purpose processors along with custom accelerators. Experimental results demonstrate(More)
