This paper deals with a study concerning the so called "smart video surveillance" system, starting from the consideration of unexpected motions. It is known that security staff, whose aim is to watch monitors and approach in case something bad and unlawful happens, in any kind of location, can keep the attention up for no more than twenty minutes, then the concentration falls down severely...
In this paper, we have scaled-up a Coarse-Grain Reconfigurable Array (CGRA) in specific widths to evaluate matrix-vector multiplication and radix-4 64-point Fast Fourier Transform (FFT) algorithms. The evaluation of different CGRAs is based on complexity in application mapping, performance and area utilization. Reducing the product development time and achieving higher reliability has always been...
In this paper, we present the mapping of Radix-2 and Radix-4 FFT algorithms using CREMA, a Coarse-Grain Reconfigurable Array (CGRA) with mapping adaptiveness. CREMA is employed to generate special purpose accelerators tailored on the specified mapping. We analyze the results for 64-point FFT targeted for OFDM processing. Both of the implementations are (4–5X) smaller and showed a speed-up of 4X when...
