Abstract :
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 the need of industry and system integrators. The low-level designers and application developers need higher performance with minimum resources. Based on our evaluation, we propose a choice of array sizes for fulfilling the needs of both system integrators and low-level designers.
