All other trademarks and registered trademarks are the property of their respective owners. All specifications are subject to change without notice. NOTICE OF DISCLAIMER: Xilinx is providing this design, code, or information as is. By providing the design, code, or information as one possible implementation of this feature, application, or standard, Xilinx makes no representation that this implementation is free from any claims of infringement. You are responsible for obtaining any rights you may require for your implemen- tation. Xilinx expressly disclaims any warranty whatsoever with respect to the adequacy of the implementation, including but not limited to any warranties or representations that this imple- mentation is free from claims of infringement and any implied warranties of merchantability or fitness for a particular purpose. Introduction This specification defines the architecture and interface requirements for the OPB EMC. This 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 ZBT™ Feature. Example asynchronous devices include the IDT71V416S SRAM and Intel 28F128J3A StrataFlash Memory. To allow the user to obtain an OPB EMC that is uniquely tailored for their system, certain features are parameterizable in the OPB EMC design. This allows the user to have a design that only utilizes the resources required by their system and runs at the best possible performance. Features •Parameterized for up to a total of four memory (Synchronous/Asynchronous) banks •Separate base addresses and address range for each bank of memory •OPB V2.0 bus interface with byte-enable support. Memory data width is independent of OPB data width (memory data width must be less than or equal to OPB data width) -Supports memory widths of 32 bits, 16 bits, or 8 bits •Memory width can vary by bank LogiCORE™ Facts Core Specifics Supported Device Family QPro™-R Virtex™-II, QPro Virtex-II, Spartan™-II, Spartan-IIE, Spartan-3, Spartan-3E, Virtex, Virtex-II, Virtex-II Pro, Virtex-4, Virtex-E Version of Coreopb_emcv2.00.a Resources Used MinMax Slices171473 LUTs63553 FFs270597 Block RAMs00 Provided with Core DocumentationProduct Specification Design File FormatsVHDL Constraints FileN/A VerificationN/A Instantiation TemplateN/A Reference DesignsNone Design Tool Requirements Xilinx Implementation ToolsISE 6.2i or later VerificationN/A SimulationModelSim SE/EE 5.8b or later SynthesisXST Support Support provided by Xilinx, Inc.
