    摘要: A system has a first plurality of cores in a first coherency group. Each core transfers data in packets. The cores are directly coupled serially to form a serial path. The data packets are transferred along the serial path. The serial path is coupled at one end to a packet switch. The packet switch is coupled to a memory. The first plurality of cores and the packet switch are on an integrated circuit. The memory may or may not be on the integrated circuit. In another aspect a second plurality of cores in a second coherency group is coupled to the packet switch. The cores of the first and second pluralities may be reconfigured to form or become part of coherency groups different from the first and second coherency groups.
