Interfacing STRATIX 3 FPGA with RS485 and RS232.

Hello sir, I am designing a hardware multipurpose board using STRATIX 3 FPGA(EP3SL340F1517C3N). I have never worked on Fpga practically. So kindly let me know how to interface this Fpga with...

Thanks.

I'm always messed up with serial and parallel communication. RS485 is serial communication while my FPGA needs parallel inputs. Then, is it necessary to perform serial to parallel conversion? Can the conversion be done by placing an additional block in between MAX3485 and FPGA? Or can this be done by VHDL coding itself?(I'm writing a VHDL code to interface all the components on my board with FPGA) Will this make my code lengthy? Please help!
