LogiCORE IP Multi-Port Memory Controller (v6.06.a)
Port Configuration
In the Port Configuration tab you can configure the parameters of each individual port. Tabs are available for Port
0-3 and Port 4-7. The Port tabs are divided into quadrants with a port number represented in each quadrant. Only
the parameters related to the current port type (selected in the Base Configuration tab) are active and editable. For
a detailed description of parameters, see Memory and Memory Part Parameters, page 7.
Advanced
The Advanced tab contains the following tabs which offer more advanced MPMC customization:
• Address Configuration
• Data Path Configuration
• Arbitration
• ECC/PM/PHY/DBG
• Misc
Address Configuration
In the Address Configuration tab, you can choose to ignore the common base addresses and configure the
addresses of each individual port.
The Use Common Port Address check box is on by default. If you do not want to use common port address, you
can deselect the check box to disable the use of common port addresses and enable the Port Addresses box. You can
then change the port addresses of each port.
The rows in the Port Addresses box are:
• Base Address: Base address of the port as specified by C_PIM<Port_Num>_BASEADDR which is described
inPer-Port Parameters, page 12.
• High Address: High address of the port as specified by C_PIM<Port_Num>_HIGHADDR which is described
inPer-Port Parameters, page 12.
• Offset: Address offset as specified by C_PIM<Port_Num>_OFFSET which is described in Per-Port Parameters,
page 12. This allows a multiprocessor system to have identical logic memory space inside each processor while
mapping each logical memory space to different physical locations inside the memory.
• SDMA Control Port Base Address: logical base address of channel (if configured as SDMA).
• SDMA Control Port High Address: logical high address of channel (if configured as SDMA).
The Restore Default Address button restores the address to common address mode.
