Abstract: In one embodiment, the present invention includes an apparatus having an adapter to communicate according to a personal computer (PC) protocol and a second protocol. A first interface coupled to the adapter is to perform address translation and ordering of transactions received from upstream of the adapter. The first interface is coupled in turn to heterogeneous resources, each of which includes an intellectual property (IP) core and a shim, where the shim is to implement a header of the PC protocol for the IP core to enable its incorporation into the apparatus without modification. Other embodiments are described and claimed.
