AM6526: Difference AM6526 vs AM6527

Part Number: AM6526


Hi all,

differences seems to related to kind of clustering two A53 cores:

I need some more background:

What does this exactly mean ?

What influence does this have on application performance ?

    DJ-NG,

    The DEVICE_ID doesn't impact performance.  It's just there to make it possible for software to "know" what features are available dynamically at run-time.

    The main difference between the AM6526 and AM6527 relates to the specific cores available:


    The difference relates to the cache topology.  The AM6526 uses cluster 0, i.e. the two CPU cores have shared cache.  This is ideal for applications using SMP (e.g. Linux SMP, etc.).  The AM6527 takes one core from each cluster.  In other words, the cores do not share cache.  This topology would be preferable in cases where you're using two different operating systems and want to minimize interaction between them, e.g. Linux on first core and RTOS on second core.

    Best regards,
