LogiCORE IP PLBV46 to AXI Bridge (v2.01.a)
Best case PLB bandwidth utilization, is calculated on the PLB by issuing back-to-back burst read and write transfers
of length 16 and observed in simulation by requesting 1000 transfers, is as shown in Table 20. For improving core
performance C_SPLB_SUPPORT_BURSTS and C_M_AXI_SUPPORTS_THREADS need to be set to 1.
