Power Consumption Estimation for S32G254

Hi,

Customer-UAES did a calculation for S32G254, as they don't have detailed parameter for S32G254, all calculation is based on current S32G274.  Assume all A53/M7 cores inside S32G254 are used, PFE is not used and LLCE is used. Other hardware interfaces are list in attachment. They calculation result is normal case -- power consumption 3.1W; worst case--4.67W.

Could you pls help to check UAES's calculation?

Thank you.

Still some concern about current customer calculation :

 

  1. They are using 274, which has 4x A53 cores, but only 2 x A53 cores for S32G254. Need PL to confirm whether they can use 1/2 x S32G274 A53 cores power consumption directly.
  2. For PCIe interfaces, not sure whether customer can calculate it separately in different speed.
  3. For SoC logic power consumption, whether 254 is same as 274? This part consume about 1/2 of total power consumption.
