High Level Synthesis: from Algorithm to Digital Circuit- P16 pptx

... chapter presents GAUT, an academic and open-source high- level synthesis tool dedicated to digital signal processing applications. Starting from an algorithmic bit-accurate specification written in ... cores will need new ESL design tools in order to raise the specification abstraction level up to the “algorithmic one”. Algorithmic descriptions enable an IC designer to focus on...
