Abstract: A compute engine includes a central processing unit coupled to a coprocessor. The coprocessor includes a media access controller engine and a data transfer engine. The media access controller engine couples the compute engine to a communications network. The data transfer engine couples the media access controller engine to a set of cache memory. In further embodiments, a compute engine includes two media access controller engines. A reception media access controller engine receives data from the communications network. A transmission media access controller engine transmits data to the communications network. The compute engine also includes two data transfer engines. A streaming output engine stores network data from the reception media access controller engine in cache memory. A streaming input engine transfers data from cache memory to the transmission media access controller engine.

Abstract: A system includes a plurality of processing clusters and a snoop controller adapted to service memory requests. The snoop controller and each processing cluster are coupled to a snoop ring. A first processing cluster forwards a memory request to the snoop controller for access to a memory location. In response to the memory request, the snoop controller places a snoop request on the snoop ring—calling for a change in ownership of the requested memory location. A second processing cluster receives the snoop request on the snoop ring. The second processing cluster generates a response to the snoop request. If the second processing cluster owns the requested memory location, the second processing cluster modifies ownership status of the requested memory location.
