Yes , I see your point. My question about the SoC option was in the following reason. Having an already configured ARm processor running for example a Linux OS, the basic functions for accessing files, reading its content are already in place. This way the focus will be on setting up the communication betwen the FPGA and the ARM processor and the calculations on the FPGA. The objective is avoid the aditional work on designing staff like handling files with an FPGA.
