Hi Bhaumik, There are two ways to do this. Either you make the changes to the or1200 itself, or create a stand-alone Wishbone-AHB bridge. Making the necessary changes to or1200 can be a bit tricky, since the wishbone interface is very integrated in the core. I know that there have been requests for a bridge component from several instances (I might come to need that for myself), so this sounds like a project that would be quite useful. If you start a project and make it available on opencores, you could probably get help from other people as well. -- Olof Kindgren ______________________________________________ ORSoC Website: www.orsoc.se Email: [email protected] ______________________________________________ FPGA, ASIC, DSP - embedded SoC design _______________________________________________ OpenRISC mailing list [email protected] http://lists.openrisc.net/listinfo/openrisc
