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)
Modern embedded MPSoC designs increasingly couple hardware accelerators to processing cores to trade between energy efficiency and platform specialization. To assist effective design of such systems there is the need on one hand for clear methodologies to streamline accelerator definition and instantiation, on the other for architectural templates and(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)
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)
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.
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)
Over the last decade many academic and industrial system synthesis and codesign tools have been proposed to designers. However most of these tools are based on IP Libraries but either these libraries are incomplete or are simply not adapted to the targets and constraints. It means that something important is missing when it comes to real implementations. We(More)
