Intel Xeon Processor C5500/C3500 Series Non-Transparent Bridge
The Intel Xeon Processor C5500/C3500 Series is the next generation of high-performance multi-core architecture targeted for embedded and storage use cases. Based on 45 nm technology, the architecture integrates multiple processor cores, memory controller, PCI express (PCIe) interface, Crystal Beach DMA engines, and IO virtualization blocks in a single chip. Augmenting several embedded features is the integration of Non-Transparent Bridge (NTB) which enables high speed connectivity between one Intel Xeon Processor-based platform to another (and other IA or non-IA platform via the PCIe interface). This paper provides a detailed look at the non-transparent bridge device integrated into the Intel Xeon Processor C5500/C3500 Series.
