Arasan's PCI Express Endpoint IP is a high-performance, low-power, and highly configurable PCIe solution designed for computing, networking, storage, wireless, server, and embedded applications. The IP is compliant with PCI Express Base Specification Rev 1.1 and Rev 2.0 and supports flexible endpoint implementations with x1, x2, and x4 lane configurations. The architecture is optimized to deliver high throughput while minimizing gate count, enabling efficient deployment in FPGA and ASIC designs. The endpoint supports advanced transaction layer capabilities such as cut-through, store-and-forward, and bypass modes, configurable outstanding requests, payload sizing, and enhanced flow-control mechanisms. Support for multiple virtual channels, traffic classes, MSI/MSI-X interrupts, advanced error reporting, and power management features enables deployment in performance-sensitive systems. The IP integrates through an industry-standard PIPE interface and supports interoperability with standard PCIe PHY solutions. Additional features including link training, lane reversal, polarity inversion, wake-up mechanisms, and link-speed negotiation simplify PCIe subsystem integration while maintaining standards compliance and interoperability.
