Providing a peripheral component interconnect (PCI)-compatible transaction level protocol for a system on a chip (SoC)

摘要

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 via one or more physical units 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.

1. A system-on-chip (SoC) comprising:
an adapter adapted on a semiconductor die to communicate with a first component in a manner compatible with a peripheral component interconnect (PCI)-compliant protocol and to communicate with a first interface in a manner compatible with a second protocol; the first interface adapted on the semiconductor die to perform a conversion of a PCI-compliant transaction to a second transaction and perform address translation to translate between a re-locatable address and a fixed address; and an interconnect adapted on the semiconductor die to provide interconnection and routing of communications between the first interface and a plurality of heterogeneous resources, each of the plurality of heterogeneous resources including an intellectual property (IP) core and an interface logic, wherein the SoC is to operate in a manner compatible with the PCI-compliant protocol and the IP core is to operate in a manner compatible with the second protocol.
