The PCI Express Adaptive Communication Hub (Peach) is an eight-core communication system on chip with four PCI Express Revision 2.0 ports, each with four lanes. Peach realizes a high-performance, power-aware, highly dependable network that uses PCI Express not only for connecting peripheral devices but also as a communication link between computing nodes. This approach opens up new possibilities for a range of communications.
