This paper proposes a framework to design energy efficient signal processing systems. The energy efficiency is provided by combining Dynamic Frequency and Voltage Scaling (DVFS) and Dynamic Power Management (DPM). The framework is based on Synchronous Dataflow (SDF) modeling of signal processing applications. A transformation to a single rate form is(More)
Stereo matching techniques aim at reconstructing disparity maps from a pair of images. The use of stereo matching techniques in embedded systems is very challenging due to the complexity of the state-of-the-art algorithms. Local stereo matching algorithms are efficiently implemented on GPU and DSP. This paper presents the optimization of the One Dimension(More)
The High Efficiency Video Coding (HEVC) standard provides up to 40% bitrate savings compared to the state-of-art H.264/AVC standard for the same perceptual video quality. Power consumption constraints represent a serious challenge for embedded applications based on a software design. A large number of systems are likely to integrate the HEVC codec in the(More)
