Abstract
A system on a chip for network devices. In one implementation, the system on a chip may include (integrated onto a single integrated circuit), a processor and one or more I/O devices for networking applications. For example, the I/O devices may include one or more network interface circuits for coupling to a network interface. In one embodiment, coherency may be enforced within the boundaries of the system on a chip but not enforced outside of the boundaries.
Claims19
An integrated circuit comprising:
- at least one processor coupled to a bus;
- a cache memory coupled to the bus to cache data for the integrated circuit;
- a memory controller coupled to the bus;
- a bridge circuit coupled to the bus:
- and
- at least one interface circuit to couple to a network external to the integrated circuit, the at least one interface circuit also coupled to the bridge circuit to allow the bridge circuit to initiate transactions onto the bus for data transfer between the bus and the at least one interface circuit.
3 more elements
In a network device, an integrated circuit containing a system thereon, comprising:
- at least one processor coupled to a bus;
- a cache memory coupled to the bus to cache data for the integrated circuit;
- a memory controller coupled to the bus;
- a plurality of interface circuits to couple to different networks to allow the network device to operate in more than one type of network;
- and
- at least one bridge circuit coupled to the bus to operate as a bridge between the bus and the plurality of interface circuits to initiate transactions between the plurality of interface circuits and the bus.
