Multi-purpose and Feature-Rich PCI Express Bridge
The bridge offers PCI Express™ (PCIe) bridging capability from a Generic
Local Bus to PCIe enabling users to add scalable high bandwidth
interconnection to a wide variety of applications including communication
line cards, surveillance systems, video capture cards, industrial control, office
automation, IP Media Servers, RAID systems and medical imaging. Many
embedded system designs utilizing PCI today can easily migrate to PCIe. The
ExpressLane™ PEX 8311 bridge can be used in Root Complex mode with the
device directly interfacing multiple local bus devices including processors and
FPGAs to a downstream PCIe port. The bridge can also function in an EndPoint
type application connecting multiple local bus components to an upstream PCIe
port.
Highly Flexible, Generic Local Bus
The PEX 8311 offers a highly flexible yet low overhead generic Local Bus
which provides a direct connection to two generic industry-standard
interconnect buses. The bus protocol can be set to the non-multiplexed
address and data mode with up to 32-bit transfers “C-Mode” or multiplexed
address/data with up to 32-bit transfers “J-Mode”. This bus can be directly
connected to many processors with minimal or no glue logic. Memory,
FPGAs, FIFOs and other devices can be simultaneously placed on this bus.
Dual Independent DMA Channels
The PEX 8311 provides two data transfer channels each with internal
independent programmable FIFOs. These channels provide independent data
transfers with the bridge initiating both the PCIe and local bus. With dual
channels, data from two different sources or bidirectional traffic can be
transferred simultaneously without the need to finish one transfer before
starting the second. Each DMA channel can use independent scatter-gather
descriptor lists for increased flexibility. The use of DMA descriptors allows
the two channels to look like multiple virtual DMA channels.
Complete Conversion from PCI Express Signaling
The PEX 8311 provides a complete local bus to PCIe translation. The bridge
is equipped with a standard PCIe port that operates as a single x1 link with a
maximum of 250 Megabytes per second of throughput per transmit and
receive directions. The single 2.5 Gbps integrated SerDes delivers the highest
bandwidth with the lowest possible pin-count. The device supports internal
queues with flow control features to optimize throughput and traffic flow.
Root Complex and EndPoint Modes
The PEX 8311 bridge supports both Root Complex and EndPoint modes of
operation. This flexibility allows a Root Complex system designer to utilize
the part as a type of “north bridge” whereby multiple Local Bus components
present including a processor, FPGAs, memory, DSP, etc., can communicate with
each other as well with downstream PCIe devices. In this case, the bridge’s
configuration and system hierarchy comes through the Local Bus. In EndPoint
mode, the bridge is configured through the PCIe port.
