MIPI ASPMI Slave IP

Overview

MIPI ASPMI Slave interface provides full support for the two-wire MIPI ASPMI synchronous serial interface, compatible with SPMI specification. Through its SPMI compatibility, it provides a simple interface to a wide range of low-cost devices. MIPI ASPMI Slave IIP is proven in FPGA environment.The host interface of the MIPI ASPMI can be simple interface or can be AMBA APB, AMBA AHB, AMBA AHB-Lite, AMBA AXI, AMBA AXI-Lite, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.
