Avalon MM Interface

Question

Hi,

I have 2 doubts.

1.I have a Processor Module which gives out PCIe bus which is connected to FPGA. In FPGA we have Registers ,UART IP core etc..which are having local bus(ADDR, DATA, R, WR). In our board , Processor Module is always the master and it reads or writes into the above mentioned peripherals. so is there any core in quartus2 or any vendor which does the pcie to local us conversion.

2.Pcie core has avalon Interface. is there any core which converts avalon mm master to standard local bus interface?.

is there any way to solve the above requirement ?.

Regards

You can always make your own avalon master (http://www.altera.com/support/examples/nios2/exm-avalon-mm.html) and/or avalon slave (http://www.altera.com/support/examples/nios2/exm-avalon-memory-slave.html) modules that form a bridge from the Avalon bus to your own bus.
