T2M PCI Express CXP Host IP


Description and Features

CXP Host core is compliant with standard CXP 1.1/1.1.1/2.0 specification. Through its compatibility, it provides a simple interface to a wide range of low-cost devices. CXP Host IP is proven in FPGA environment. The host interface of the CXP can be simple interface or can be AHB, AHB-Lite, APB, AXI, AXI-Lite, Tilelink, OCP, VCI, Avalon, PLB, Wishbone or custom buses.
