T2M Automotive eSPI Master / Slave Controller IP

eSPI Master / Slave Controller IP

Description and Features

The eSPI controller has a comprehensive feature set, is simple to use, can be synthesized, and is compliant with the eSPI standard protocol. It gives a variety of inexpensive devices a straightforward interface thanks to its eSPI compatibility. In an FPGA context, ESPI controller IP has been tested. The eSPI controller's host interface options include a basic interface, AMBA APB, AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone, or a custom protocol. Verilog and VHDL both natively support eSPI Controller IP.
