Real Time Clock is used to generate precise time, date, alarm pulse after programmed period and keeps track of events, compatible with standard protocol of RTC specification. Through its RTC compatibility, it provides a simple interface to a wide range of low-cost devices. RTC IIP is proven in FPGA environment.The host interface of the RTC 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.
