Hi Experts,
My customer is asking APP for both AM6526 and AM6546.
Could you please give us the number?

What does APP refer to? Is it Adjusted Peak Performance value as stated in https://www.bis.doc.gov/index.php/documents/product-guidance/865-practioner-s-guide-to-adjusted-peak-performance/file#:~:text=Vector%20systems%20continue%20to%20be,WT%20values%20of%20digital%20computers and responded to in ahttps://e2e.ti.com/support/processors-group/processors/f/processors-forum/1257261/am6442-the-performance-of-cpu-am6442/ for anotehr device on the family? If this is the case the arithmetic as guided in the first link is:
A53 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, only with 32b floats) so Wi is 0.3.
R5 does a 64b floating point add in 3 cycles if pipelined (other 64b float operations are much slower), Ri is 0.33. No vectors for 64b floats, Wi is 0.3.
Below is multiply with clock (800MHz A53 and 400MHz R5) and the number of cores (2 and 4 for A53) the answer in Tera. Assumes on 64b float FMAC on A53 per clock, and one 64b float add in 3 clocks on R5.
A53 are 2*2*0.3*0.8G is 0.00096 Weighted TeraFLOPS R5's are 2*0.33*0.3*0.4G is ~0.0000792 Weighted TeraFLOPS so less than 0.0010392 weighted TeraFLOPS for AM6526.
A53 are 4*2*0.3*0.8G is 0.00192 Weighted TeraFLOPS R5's are 2*0.33*0.3*0.4G is ~0.0000792 Weighted TeraFLOPS so less than 0.0019992 weighted TeraFLOPS for AM6546.
