T2M Automotive RapidIO EndPoint Controller IP

RapidIO EndPoint Controller IP

Description and Features

RapidIO EndPoint interface provides full support for the RapidIO EP synchronous serial interface, compatible with RapidIO Interconnect 2.2 specification. Through its RapidIO EP compatibility, it provides a simple interface to a wide range of lowcost devices. RapidIO EP IP is proven in FPGA environment. The host interface of the RapidIO EP can be simple interface or can be AMBA APB, AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.
