The paper contains the analysis of the application possibilities offered by the new generation of the FPGA chips. The new generation of the FPGA chips contain DSP blocks. The new functionalities are well suited for the application in the TESLA LLRF cavity simulation and control system (SIMCON). A debate on the programming methods of the new chips and the algorithm parameterization was presented. The aim of the, FPGA chip based, system analysis is the optimal chip usage to increase the maximum frequency at which the system can work efficiently, and the optimal usage of the accessible chip resources (DSP blocks). The exemplary results for a few practical calculated implementations were presented and analyzed. The implementations included some basic DSP operations performed in the FPGA chips of Altera and Xilinx. There were compared the results for a few different chips. The TESLA superconducting cavity simulator was efficiently implemented. The results were presented for the first time, for the pure FPGA/VHDL solution. The realization costs were debated in the dependence of given system parameters and the applied type of the FPGA chip.
