The MosChip MCS9250 PCI-to-PCI Bridge provides a high performance connection path between two peripheral components interconnect (PCI) buses. Transactions occur between masters on one PCI bus and targets on another PCI bus, and the MCS9250 allows bridged transactions to occur concurrently on both buses. The bridge supports burst-mode transfers to maximize data throughput, and the two bus traffic paths through the bridge act independently.
