I'm implementing some Image Processing algorithms in VHDL, I'm testing these algorithms on the FPGA Spartan IIE xc2s200E. Is there any way to use the JTAG pins
of the xc2s200E for user I/O? I want to download data from the PC, via a Parallel Port to JTAG Port on the xc2s200E.
not directly but you can use the BSCA primitive to implement some custom gateway that passes the data to your ip core

Sorry, but I'm a very beginner of the FPGA technologies. What does "the BSCA primitive" mean exactly? Do you know any examples that they could help me??
Thanks.

sorry BSCAN
it allows user logic to added into JTAG chain. its mostly 'advanced' topic - so there arent much easy to use examples.
you can download the xilinx picoblaze stuff some of the files there use the BSCAN to load BRAMs over jtag
antti
Do you know any util links where I can fund materials helping me.

Do you think that it's possible to develop a bi-directional communication between FPGA and Computer Host using Picoblaze? Sorry, but I'm very confused on the way that I can do it.

I just gave you a reference where the BSCAN is used. you can use to implement different kind of protocols the picoblaze has nothing todo with it, it was just an example application where BSCAN is used.
if you are confused then read the JTAG stuff BSCAN allows you to add custom scan chain in FPGA fabric, whatever you do there its up to you.
