    摘要: 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. In one implementation, the compute engine performs different network services, including but not limited to: 1) virtual private networking; 2) secure sockets layer processing; 3) web caching; 4) hypertext mark-up language compression; 5) virus checking; 6) firewall support; and 7) web switching.

    摘要: A compute engine's central processing unit is coupled to a coprocessor that includes application engines. The central processing unit initializes the coprocessor to perform an application, and the coprocessor initializes an application engine to perform the application. The application engine responds by carrying out the application. In performing some applications, the application engine accesses cache memory—obtaining a physical memory address that corresponds to a virtual address and providing the physical address to the cache memory. In some instances, the coprocessor employs multiple application engines to carry out an application. In one implementation, the application engines facilitate different network services, including but not limited to: 1) virtual private networking; 2) secure sockets layer processing; 3) web caching; 4) hypertext mark-up language compression; 5) virus checking; 6) firewall support; and 7) web switching.

    摘要: 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.

    摘要: A system for processing data includes a first set of cache memory and a second set of cache memory that are each coupled to a main memory. A compute engine coupled to the first set of cache memory transfers data from a communications medium into the first set of cache memory. The system transfers the data from the first set of cache memory to the second set of cache memory, in response to a request for the data from a compute engine coupled to the second set of cache memory. Data is transferred between the sets of cache memory without accessing main memory, regardless of whether the data has been modified. The data is also transferred directly between sets of cache memory when the data is exclusively owned by a set of cache memory or shared by sets of cache memory. In one implementation, the above-described cache memory arrangement is employed with a compute engine that provides different network services, including but not limited to: 1) virtual private networking; 2) secure sockets layer processing; 3) web caching; 4) hypertext mark-up language compression; 5) virus checking; 6) firewall support; and 7) web switching.
