About Preesm

Presentation

PREESM is an open source rapid prototyping tool. It simulates signal processing applications and generates code for heterogeneous multi/many-core embedded systems. Its dataflow language eases the description of parallel signal processing applications.

The PREESM tool inputs are an algorithm graph, an architecture graph, and a scenario which is a set of parameters and constraints that specify the conditions under which the deployment will run. The chosen type of algorithm graph is a parameterized and hierarchical extension of Synchronous Dataflow (SDF) graphs named PiSDF. The architecture graph is named System-Level Architecture Model (S-LAM). From these inputs, PREESM maps and schedules automatically the code over the multiple processing elements and generates multi-core code.

PREESM supports and has been used to generate code for:

x86 multiprocessors over Linux & Windows
Texas Instruments Keystone I & II
Kalray MPPA many-core (Bostan)
Xilinx Zynq SoC
ARM Big.LITTLE & Multi-core ARM over Linux

Installation

Instructions for installing Preesm can be found in the documentation. Preesm consists in Eclipse plug-ins. If you are already familiar with Eclipse update sites, the different ways for getting Preesm are detailed in the Getting Preesm part.
