Augmented reality (AR) is a highly interdisciplinary field which has received increasing attention since late 90s. Basically, it consists of a combination of the real scene viewed by a user and a computer generated image, running in real time. So, AR allows the user to see the real world supplemented, in general, with some information considered as useful,(More)
Bidimensional convolution is a low-level processing algorithm which is of great interest in many areas, but its high computational cost limits the size of the kernels, especially in real-time embedded systems. This work describes the process of designing 2-D filters with large kernels (up to 50 × 50 coefficients) using the Impulse CoDeveloperTM high-level(More)

An FPGA-based approach is proposed for implementing a compression system developed specifically for the signal of phonocardiogram. The compression method offers better rate and distorsion than standard audio compression techniques. Both the algorithm and the details on the solutions adopted for its implementation are presented in this paper.
The complexity of hardware design methodologies represents a significant difficulty for non hardware focused scientists working on CNN-based applications. An emerging generation of Electronic System Level (ESL) design tools is been developed, which allow software-hardware codesign and partitioning of complex algorithms from High Level Language (HLL)(More)
This paper describes the design and the implementation of an embedded system based on multiple FPGAs that can be used to process real time video streams in standalone mode for applications that require the use of large Multi-Layer CNNs (ML-CNNs). The system processes video in progressive mode and provides a standard VGA output format. The main features of(More)
