How to set the priority of master interface?

Hi!

There are two master interfaces connect to a slave interface,is there a method to set the priority of the two master interfaces to read the slave interface?

For example,the data_master of CPU and the avalon_master of lcd_core_s are connected to the avalon_slave_0 of SRAM_512K_16Bit.I just want to give the higher priority to the avalon_master than the data_master.

thank you in advance!

    Yes ...

    The SOPC builder will show a priority (IIRC 0 to 3) on the intersection (where you link the master and slave). Unfortunately I can't remember how you enable it :-(

    And I don't remember it saying whether 0 or 3 is the highest priority!
