OPB EMC

"This IP module supports data transfers between the On-chip Peripheral Bus (OPB) and external synchronous and asynchronous memory devices. Example synchronous devices for use with this controller are the synchronous Integrated Device Technology, Inc. IDT71V546 SRAM with ZBTâ„¢ Feature. Example asynchronous devices include the IDT71V416S SRAM and Intel 28F128J3A StrataFlash Memory. The Xilinx EMC design allows the customer to tailor the EMC to suit their application by setting certain parameters to enable/disable features.
