Table 1. CAPTR_WRBEAT (0x22DC)
Bit Default Value Access Type Description
31:0 0x0000_0000 RO This is used for calculating average write bandwidth by windowing technique.

It shows total number of write beats captured in a particular window of certain number of AXI clock cycles. The windowing technique is enabled using CAPTURE_ENABLE(0x42DO) and size of window is defined using START_ADDR (0x42D4) and END_ADDR(0x42D8).

The write bandwidth is calculated as WRITE_BW= (No. of write beats captured/Window size )* Total bandwidth.

Total bandwidth = (AXI_DATA_WIDTH)*(AXI_CLOCK_FREQUENCY)

Window size = END_ADDR - START ADDR

The write efficiency is calculated as WR_EFF = (No. of write beats captured/ Window size) *100 .
