Connecting Multiple Memory Devices

The nature of your FPGA design may warrant the use of several memory devices, possibly of differing type, each of which requires to be mapped into a specific location within the processor's address space. Within the OpenBus System, this can be readily achieved through use of an Interconnect component.

Figure 1 illustrates the use of an Interconnect component to connect to SRAM, SDRAM and Block RAM, via the corresponding, and appropriately-configured, memory controllers.
