PPC LUTS registers

Mar 02, 2006 1 Replies

Hi i was wondering which would be the best way to get the PPC on a virtex II pro to control the 4 inputs on a LUT, so far i have tried using GPIO/IPIF (using xilinx EDK create import peripheral dialogue) to control registers over the plb or opb bus but how would i instantiate a xilinx primitive element lets say a srl16 and connect 4 of the register values to its inputs and one to its output?



Is this approach even possible has anyone tried driving the inputs on internal fpga elements?



any ideas help would be greatly appreciated thanks shane



If you want to have a tiny and very fast solution you can use the OCM interface and directly connect logic resources to it.

UltraController-II should give you a good starting point to accomplish this. See XAPP575 for more information
