There is a General Programming Interface(GPIF) in FX2LP(CY7C68013A) which is a parallel interface. You can go through that. You can refer to AN61345 where FX2LP is interfaced with FPGA over GPIF.Please check if this suits your application.
You can find the App Note here(with the source code):
If this does not suit your application, please provide the details of your application.
Also you can go through the GPIF section of FX2LP TRM for more details on parallel interface which can be found here:
