AM4372: MPU load supporting two GBit ethernet PHYs

BO

Part Number: AM4372

Can you provide benchmarks for AM4372 supporting two DP83867 at maximum data throughput?

What processor performance is left for processing other data?

Regards Bernd

    Hi,

    The answer to this depends on the OS that is being used as that will have a significant impact on performance. Linux is the only OS that TI has throughput performance numbers for networking.

    One thing to consider is the topology, is it a dual MAC or a daisy chain configuration for the CPSW. If a daisy chain topology then the pass-through traffic does not impact the ARM in the AM4372. 

    One recommendation is that even if the OS is not Linux a "what if" experiment could be done with a AM437 EVM and using the iperf and cpuloadgen utilities to determine an approximation if the AM437 could handle the network and compute requirements for the application.

    Best Regards,
