89HPES32NT8AG2 Product details

Product Description
With Non-Transparent Bridging functionality and innovative Switch
Partitioning feature, the PES32NT8AG2 allows true multi-host or multiprocessor communications in a single device. Integrated DMA controllers enable high-performance system design by off-loading data transfer
operations across memories from the processors. Each lane is capable
of 5 GT/s link speed in both directions and is fully compliant with PCI
Express Base Specification 2.1.
A non-transparent bridge (NTB) is required when two PCI Express
domains need to communicate to each other. The main function of the
NTB block is to initialize and translate addresses and device IDs to
allow data exchange across PCI Express domains. The major functionalities of the NTB block are summarized in Table 1.

Features
 High Performance Non-Blocking Switch Architecture
– 32-lane, 8-port PCIe switch with flexible port configuration
– Integrated SerDes supports 5.0 GT/s Gen2 and 2.5 GT/s
Gen1 operation
– Delivers up to 32 GBps (256 Gbps) of switching capacity
– Supports 128 Bytes to 2 KB maximum payload size
– Low latency cut-through architecture
– Supports one virtual channel and eight traffic classes
 Port Configurability
– Eight x4 switch ports
• Adjacent x4 ports can be merged to achieve x8 port widths
– Automatic per port link width negotiation
(x8  x4  x2  x1)
– Crosslink support
– Automatic lane reversal
– Per lane SerDes configuration
• De-emphasis
• Receive equalization
• Drive strength
 Innovative Switch Partitioning Feature
– Supports up to 8 fully independent switch partitions
– Logically independent switches in the same device
– Configurable downstream port device numbering
– Supports dynamic reconfiguration of switch partitions
• Dynamic port reconfiguration — downstream, upstream,
non-transparent bridge
• Dynamic migration of ports between partitions
• Movable upstream port within and between switch partitions
 Non-Transparent Bridging (NTB) Support
– Supports up to 8 NT endpoints per switch, each endpoint can
communicate with other switch partitions or external PCIe
domains or CPUs
– 6 BARs per NT Endpoint
• Bar address translation
All BARs support 32/64-bit base and limit address translation
• Two BARs (BAR2 and BAR4) support look-up table based
address translation
– 32 inbound and outbound doorbell registers
– 4 inbound and outbound message registers
– Supports up to 64 masters
– Unlimited number of outstanding transactions
 Multicast
– Compliant with the PCI-SIG multicast
– Supports 64 multicast groups
– Supports multicast across non-transparent port
– Multicast overlay mechanism support
– ECRC regeneration support
 Integrated Direct Memory Access (DMA) Controllers
– Supports up to 2 DMA upstream ports, each with 2 DMA channels
– Supports 32-bit and 64-bit memory-to-memory transfers
• Fly-by translation provides reduced latency and increased
performance over buffered approach
• Supports arbitrary source and destination address alignment
• Supports intra- as well as inter-partition data transfers using
the non-transparent endpoint
– Supports DMA transfers to multicast groups
– Linked list descriptor-based operation
– Flexible addressing modes
• Linear addressing
• Constant addressing
 Quality of Service (QoS)
– Port arbitration
• Round robin
– Request metering
• IDT proprietary feature that balances bandwidth among
switch ports for maximum system throughput
– High performance switch core architecture
• Combined Input Output Queued (CIOQ) switch architecture
with large buffers
 Clocking
– Supports 100 MHz and 125 MHz reference clock frequencies
– Flexible port clocking modes
• Common clock
• Non-common clock
• Local port clock with SSC (spread spectrum setting) and port
reference clock input
