This might not be a typical Stackoverflow question, but I wasn't sure where I could get this answered.
I have Verilog code to multiply two matrices and read them out, but my throughput is limited significantly by the number of I/O pins on the Xilinx Virtex 5 board (http://www.xilinx.com/support/documentation/boards_and_kits/ug347.pdf) we would be using. (I am designing on the Xilinx ISE)
How do I know which of the pins mentioned in the datasheet may be used as digital output pins? I've been through the datasheet several times, but I can't figure out which of the pins may be used for reading my matrices out (I estimated the number to be ~20-30, but not sure).
PS: I'd like to use every output pin I have, since we shan't be implementing on the board, but just calculating theoretical maximum throughput)
