Stereo matching is one of the most used algorithms in real-time image processing applications such as positioning systems for mobile robots, three-dimensional building mapping and recognition, detection and three-dimensional reconstruction of objects. In order to improve the performance, stereo matching algorithms often have been implemented in dedicated hardware such as FPGA or GPU devices. In this...
Recently, spiking neural networks (SNNs) have obtained the interest of machine learning researchers due to the rich dynamics shown by these information processing models. One of the most important problems that must be addressed for implementing efficient SNNs is the information encoding. In this paper, an implementation of a high-performance hardware architecture for population information coding...
Sine and cosine waves have been used in countless applications; in recent research on software defined radio (SDR), digital modalities of sine and cosine waves have received special attention. SDR involves highly reconfigurable resources and uses digital generated waves for modulation and demodulation of signals. Coordinate rotation digital computer (CORDIC) is a well known algorithm used to approximate...
The present work focuses on the development of a reconfigurable systolic-based architecture for low-level image processing. The architecture is customizable providing the possibility to perform window operations for masks of 3 times3, 5 times5 and 7 times7 coefficients. A 2D systolic array of processing elements have been implemented, based on parallel modules with internal pipeline operation where...
