Hi,

Could you tell me the Adjusted Peak Performance (APP) of AM5728?

Hi,

I will ask the factory team to comment. They will respond here.

Here is the quick math for AM5728 APP value

A15 does 1 DP FMAC instruction (FMAC is 2 FLOPS, multiply and add) in 1 cycle, so peak floating point capability (Ri) is 2. It is not vector (with 64b floats) so Wi is 0.3.

C66x does 4 DP float operations per cycle, Ri is 4. Not vectors as defined by export control for DP floats, Wi is 0.3.

Multiply with clock and the number of cores the answer in Tera.

A15's is 2*0.3*1.5G is 0.0009 Weighted TeraFLOPS C66x's is 4*0.3*0.75G is 0.0009 Weighted TeraFLOPS

AM5728 is 0.0018 Weighted TeraFLOPS

You can refer to page 6 "Technical Notes On Adjusted Peak Peformance" on additional background and notes

Hi Mukul,

Thank you for your reply.

AM5728 have two A15 core and two C66x core, so I think AM5728 is 0.0072 Weighted TeraFLOPS. right?

Hi H.U.
Oops yes I think what I mentioned above works for AM5718. For AM5728 is should be 0.0036, let me know why you thought it is 0.0072.

Hi Mukul,

My calculation was wrong. AM5728 is 0.0036 Weighted TeraFLOPS!!
Thank you!
