Unfortunately, due to the fixed size of fpga devices, the RS decoder is not only constrained by the required timing of the system, but also by the size of the targeted device.

This research will facilitate the decision-making process for selecting a reconfigurable device for a RS decoder, implementing the Berlekamp-Massey Algorithm. Partial Reconfiguration Fpga Thesis, partial and dynamic, fPGA reconfiguration for esat. ( ) 2 choose the polynomial as f x x. An Open-Source Partial Reconfiguration Tool-Kit for Xilinx fpgas This thesis presents a new PR toolkit called further research into partial reconfiguration and fpga productivity oriented design tools.
