eSPI controller is full-featured, easy-to-use, synthesizable design, compatible with standard protocol of standard eSPI specification. Through its eSPI compatibility, it provides a simple interface to a wide range of low-cost devices. ESPI controller IP is proven in FPGA environment. The host interface of the eSPI controller can be simple interface or can be AMBA APB, AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol. eSPI Controller IP is supported natively in Verilog and VHDL.
