PCIe solution is another wave of high-speed transmission technology

PCIe can be used for inter-chip and inter-chip interconnects, and its interconnect standards have been widely adopted, including: consumer electronics, networking equipment, enterprise storage, industrial systems, data centers, solid state drives, embedded computing and cloud computing. . The PCIe interface is also available for FPGA and SoC devices, providing designers with flexible and high-performance system data transfer solutions. As a new generation of new graphics architecture that provides a lot of bandwidth and rich features, PCIe can greatly increase the bandwidth between CPU and GPU. For the end user, this is definitely a benefit: not only can you feel the cinematic image The result is a seamless multimedia experience. AVAGO, the world's leading leader in PCIe switching technology, provides a low-latency, low-power solution for PCIe designs to meet different market and application needs.

The PCIe bus is a point-to-point serial connection device connection. Point-to-point means that each PCIe device has its own independent data connection, and the concurrent data transmission between each device does not affect each other. The third generation of this interconnect technology (8Gbps per link) supports shared I/O and clustering and provides system designers with tools that make their designs optimized and efficient. To meet the needs of the market segment, AVAGO introduces high-performance, flexible, small PCIe products, including: ExpressFabric-based PCIe3.0 switch chip, ExpressLane PCIe 2.0 and PCIe 3.0 switch, PCIe to USB3.0 controller and PCIe To USB2.0 controller, PCIe bridge chip. AVAGO PCIe products have outstanding performance and unique features: Dual CastTM, Read PacingTM, integrated direct memory access (DMA) engine, non-transparent (NT) port, spread spectrum clock (spread spectrum) Clock, SSC) Isolation, control of internal states and settings, and miniaturization through the I2C interface. At present, these feature-rich products have been distributed by Shiqiang, the largest authorized agent of AVAGO.

The PEX9700 series offers designers a wide range of PCIe switch chips with port densities ranging from 5 to 25, from 12 to 97 channels, and fully compliant with the PCI-SIG PCIe 3.0 (Gen 3) specification. The new generation of switching chips realizes multi-node cluster system interconnection through PCIe architecture, which can directly access 3 memories, up to 6 hot-swap controllers, support 24-channel window connection, and have dedicated X1 PCIe port switch management and time expansion. Frequency clock isolation and independent reference clocks, without the need to change existing standard software and driver software.

The ExpressLane Switch PEX8700 Series (PCIe Gen 3) has a maximum of 96 channels and a maximum of 24 ports, supporting access control services and hot swap. The series features a highly flexible port configuration with non-transparent ports, DMA channels, and peer-to-peer back-to-back data transfer. The new family of PCIe switches has a broad product portfolio with high performance, low latency, and low power consumption.

The PCIe bridge chip PEX8100 series provides forward and reverse bridging, allowing designers to continue to use PCI and PCI-X in PCIe-based systems, enabling seamless connectivity from PCIe to PCI/PCI-X and the convergence of both systems. The PEX8100 series of bridged chips provide advanced error reporting with the advantages of high transfer rate, ease of use, low PCB footprint and lowest power consumption. These new bridge chips allow designers to build PCIe-based switching fabrics, large I/O, and storage devices without the hassle of high latency, high power, and bandwidth limitations associated with cascading multiple small switch chips. Reduced CPU usage load.

To meet the needs of dense data applications, ultra-large scale computing and modern data centers. AVAGO offers high performance and low power solutions for inter-device connectivity and is currently used in 100 million PCIe ports. AVAGO's PCIe-based switching products enable PCIe for data communication between devices on a single rack, reducing inherent latency and power consumption, greatly improving device performance and device-to-device communication.

PCIe technology has become ubiquitous. At present, many manufacturers around the world have adopted to support I/O endpoint sharing, and the cost and power consumption of the system have been reduced. PCIe-based shared I/O endpoints are expected to revolutionize the multi-billion dollar data center market. Looking to the future, the fourth-generation PCIe with speeds up to 16 Gbps per link will only help speed up PCIe technology into new market segments and expand, and it will be easier and more economical to design and use.
