Display Interface Unit (DIU)
10.3.3.22 Priority Look Up Table Register (PLUT)
The Priority Look Up Table Register (PLUT), shown in
transactions relative to other initiators on the DDR DRAM buses. The PLUT register includes the eight
Priority Look Up Table components. A 4-bit priority output is selected from this look up table according
to the input buffer filling status. This register must be configured so that the DIU can escalate its priority
dynamically. See
