SDIO Host Controller IIP

The SDIO Host IIP core supports the SD Host Controller Specification version 4.0 and compatible with SDIO version 4.10 specification. Through its compatibility, it provides a simple interface to a wide range of low-cost devices. SDIO HOST IIP is proven in FPGA environment. The host interface of the SDIO can be simple interface or can be AMBA APB, AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.

SDIO Host Controller IIP is supported natively in Verilog and VHDL
