I have an IP with built-in master DMA controller which transfer data between system memory (DLMB) and internal IP buffer through AXI4 interface. UBlaze is connecting to local memory via LMB. How to integrate this IP into MicroBlaze system to do DMA operation?

If the DMA IP has AXI master interface, you need to have AXI interface with system memory. But you have mentioned that it has LMB interface.
You can consider migrating system memory to AXI, including MUBlaze.

There may be some registers in DMA IP, to configure and initiate the transfers.
Generally IP vendors provide driver for the IP, try using it.
