You should be able to create something using the system console. See http://www.altera.com/literature/hb/qts/qts_qii53028.pdf. I think in particular bytestream_send and bytestream_receive. You can then write some TCL to save your data to a file and perform your operations.

Cheers,

Try using the System Console and writing your data capture PC application in TCL.

I had similar requirement in a past project, and ended up deleting the JTAG UART and instead grabbed the data directly from RAM with a buffer handshake arrangement between the FPGA and the PC.
