Synopsys DesignWare IP First to Support Final Release of PCI Express 3.0 Specification

In addition, Synopsys has enhanced its DesignWare digital controllers for PCI Express with new features including support for the latest PIPE 3.0 specification, PCI-SIG Engineering Change Notifications 256-bit datapath and embedded DMA engine, all of which provide performance improvements for the PCIe interface. The DesignWare IP for PCI Express 3.0 is currently being used by leading semiconductor companies developing high-performance enterprise computing system-on-chips designs.

The DesignWare portfolio of silicon-proven digital controllers for PCI Express 3.0 includes Endpoint, Root Complex, Switch and Dual Mode cores, enabling designers to easily integrate the 8.0 GT/s PCI Express 3.0 interface into their SoC designs with less risk and improved time-to-market.

The Newest PCI Express features will be demonstrated at the IP Summit at SNUG San Jose, March 30th at the Santa Clara Convention Center. For more information on the IP Summit, please visit http://www.synopsys.com/IP/Pages/IPSummit2011.aspx

In addition to supporting the final release of the PCIe 3.0 base specification (version 1.0), the DesignWare digital controllers have been enhanced to support several PCI-SIG ECNs, a 256-bit datapath option and an embedded DMA engine:

*The optional ECN's supported by the DesignWare digital controllers enable power reduction and increased performance for specific applications. Supported ECNs include: TLP Processing Hints, ID Based Ordering, Atomic Operations, BAR Resizing, Extended TAGs, Latency Tolerance Reporting and Optimized Buffer Flush/Fill.

*The new 256-bit datapath targets SoCs for the enterprise computing market that require a 16 lane PCIe 3.0 interface. The DesignWare digital controllers for PCI Express with 256-bit datapath are designed to handle multiple packets arriving in a single clock cycle, which provides a performance advantage over other solutions that simply scale the data bus of a 64-or 128-bit controller.

*The embedded DMA engine offloads the main SoC processor when moving large amounts of data between the PCIe interface and the rest of the system, thereby improving system performance and latency. The embedded DMA engine supports the native application interface or ARM AMBA AHB and AXI3 bridges while also supporting advanced features such as multiple channels, interleaving, linked list and full duplex operation.

LeCroy has worked closely with Synopsys to continuously conduct interoperability testing between our products as the PCI Express 3.0 specification evolved, resulting in proven products that have been demonstrated with hardware platforms at industry events, said Joe Mendolia, vice president at LeCroy. Our collaboration through the years has provided designers with PCI Express IP, test equipment and software tools that help lower the risk of incorporating the PCI Express interface into their designs.

As a leading provider of PCI Express IP, Synopsys continues to make technology advancements that give designers access to high-quality IP solutions that are interoperable and compliant to the latest standards, said John Koeter, vice president of marketing for the Solutions Group at Synopsys. By supporting the final PCI Express 3.0 specification and adding the new 256-bit controller and embedded DMA engine, Synopsys helps designers meet the high-performance PCI Express 3.0 interface requirements of their designs for the enterprise computing market.
