Abstract
In recent years, hardware architectures have evolved significantly, drawing increasing attention toward reconfigurable and parallelized models — systems capable of balancing flexibility and performance. The growing demand for such solutions has led Coarse-Grain Reconfigurable Architectures (CGRA) to become one of the most widely adopted approaches, as they can adapt to different computational problems and are particularly suitable for numerical and data-parallel applications. This thesis focuses on the design of a parametric CGRA composed of an NxN matrix of Processing Elements (PEs), where both the size and the interconnectivity between PEs can be modified. A Direct Memory Access (DMA) communication system has been integrated to generate AXI-Stream data flows, ensuring efficient frame loading and continuous data transfer toward the matrix.
An important part of the work was dedicated to the study of interconnections among the processing elements
