hi,
I would some explaination on why CPU got different core. For exemple in médiatek 9200+, that i use got 1*Cortex X3,3*Cortex A715,4*Cortex-A510.
I supose that every core type is designed to procees some type of data and not other or some type of instruction and not other. I ask the question because i am using massive multi core threading.
Each time is it 4 pthread at the time. I have try 2 by 2 but it is daoble time, which means that SIMD work fine.
But why core are different ? and what for ?
thanks.
Broadly it allows the chip to cover more of the performance-to-energy-efficiency space, so you get great battery life and thermals for typical software while still being able to have great performance for single thread heavy workloads where you really need the bigger cores extra performance.

thank you for the documentation. So i anderstand why speed drop after processing several frames. It is more for energy and heat réduction. Specially for application that bring quikly the temperature to 44 dédreés.
just time to my brain start to work.
With the new DanamiC Soc configuration we could expect in the futur to be able to adresse functions to a processor. So in case of SIMD instruction and input data could be loaded once for the all time of the application. It is just an idea. Spécilly of industrial purpose.
what do you think of this eventuality ?
