Microcrocontroller based development boards interfacing to GPIB

Hi, 

I am working on a new multimeter design. I need to add the GPIB interface to this instrument. 

I found two chips supporting GPIB interface:

1. NI TNT4882

2. NI-NAT9914-Serie

Is there any reference designs available for using these chips. I am looking for a readily available microcontroller designs that can drive either of these interface chips. 

It would be great if someone can point me in the right direction.

Thanks, 

Arvind
