LPC controller

[Altera_Forum]

Hi, 

 Do Altera FPGAs support LPC (Low Pin Count) controller as soft-IP core? I couldnt find it. I am having to design a system where a CPU interacts with the FPGA through the LPC bus apart from PCIe.  Or would I have to code my own controller?  Thanks, Satish

Have you tried looking at opencores.org?  I vaguely recall looking at the LPC interface and it didn't look too hard to code a controller for it. If opencores does not have anything you want to use, code up an interface, and a bus functional model, and if you have trouble, post the code here.   Note that if you post code with a Modelsim testbench you're more likely to get a response :)  Cheers, Dave

Thanks very much for the confirmation. 

 I would look for it in open cores, else sit down to code one myself.  Regards, Satish

I want help about Lpc bus controller, I want to connect my FPGA throw lpc to Motherboard(lpc host ) ,I want to use only Firmware memory and Firmware memory write Cycles.I see Lattice document but I can't find any verilog code , please help me. 

thank you.

The source code for the Lattice controller is licensed only for use on Lattice devices. 

 You'll probably have better luck with the OpenCores one as a starting point. http://opencores.org/project,wb_lpc

Wishbone is described here. http://opencores.org/project,wishbone,wishbone 

 If you don't want to use it, you would remove it and replace it with something else (Avalon-MM, ...)
