A.1. Derived Parameters from PMON IP
The following parameters can be derived through a combination of two or more counters set to specific AX4 events. The formula uses the following AXI4 parameters:
- AR - Read address channel
- R - Read data channel
- AW - Write address channel
- W - Write data channel
- B - Write response channel
- Total traffic duration - Number of cycles from first AR | AW | W to last transaction on R | B channel.
Equations
Average number of data transactions per cycle =
Read efficiency =
Write bandwidth =
Read latency =
Write latency =
You can also measure these AXI4 sub-channel efficiencies using the following equations:
Read address channel efficiency =
Read data channel efficiency =
Write command channel efficiency =
Write data channel efficiency =
Write response channel efficiency =
