Description
HBM3 interface provides full support for the HBM3 interface, compatible with draft JEDEC specification version 1.02 and DFI-version 4.0 or 5.0 specification Compliant. Through its HBM3 compatibility, it provides a simple interface to a wide range of lowcost devices. HBM3 IP is proven in FPGA environment. The host interface of the HBM3 can be simple interface or can be AMBA AHB, AMBA AHB-Lite, AMBA APB, AMBA AXI, AMBA AXI-Lite, Tilelink, OCP, VCI, Avalon, PLB, Wishbone or Custom protocol.
