Abstract
A system including a gasket communicatively coupled between a unified northbridge (UNB) having a cache coherent interconnect (CCI) interface and a processor having an Advanced eXtensible Interface (AXI) coherency extension (ACE). The gasket is configured to translate requests from the processor that include ACE commands into equivalent CCI commands, wherein each request from the processor maps onto a specific CCI request type. The gasket is further configured to translate ACE tags into CCI tags. The gasket is further configured to translate CCI encoded probes from a system resource interface (SRI) into equivalent ACE snoop transactions. The gasket is further configured to translate the memory map to inter-operate with a UNB/coherent HyperTransport (cHT) environment. The gasket is further configured to receive a barrier transaction that is used to provide ordering for transactions.
