IP Configuration Graphical User Interface
The IP Configuration interface offers a convenient and user-friendly way to configure a system. You can invoke the
IP Configurator GUI within XPS by double-clicking the MPMC IP in the System Assembly View, or by
right-clicking MPMC and selecting Configure IP. The tabs in the interface are:
• Base Configuration
• Memory Interface
• Port Configuration
• Advanced
To create a functional MPMC, you need to use the following three tabs only:
• Base Configuration: select the port type for each active port and remove unused ports between active ports
• Memory Interface: select the memory part and configure the memory settings
• Port Configuration: set the parameters for each port
The Advanced tab contains advanced features such as per-port addresses, per-port datapath configuration,
arbitration algorithms, performance, and debugging. This tab is intended for advanced users only.
Base Configuration
MPMC provides up to eight ports for accessing the memory; each port can be configured to a different bus or port
type. For Spartan-6 devices, choose the MCB port configuration first, using the pull-down menu to the right of the
MPMC diagram. Depending on Spartan-6 FPGA MCB port configuration, the maximum number of ports could be
limited to six or fewer ports. The Base Configuration tab lets you set:
• Port types of the eight available ports: the drop-down box contains INACTIVE, XCL, PLBv46, SDMA, NPI,
PPC440MC, VFBC, and MCB.
Depending on the FPGA architecture and port configuration, some PIM types might not be available.
• Common base addresses
