Hi Friends, greetings of the day...
I am new to this Arm community and very beginner to work on Arm cortex...
I am doing some investigation on a multi-core processor.
1. Can some one please tell me what is the power consumption of arm cortex A5 core ?
There is a default core from which i am going to enable A5 core and measure the current.
2. Should there be any change in the power consumption, if A5 is operating at different clock rates?
Hope my question is clear and sorry if there is any mistake : )
Please reply... Thanks
I dont know exactly memcpy is from i guess it is from string.h.
But When i did step by step debugging of memcpy function in both cores, i saw that the memcpy implementation is different for M4 and A5 ( Assembly code).
What is the need of FPU in memcpy function?
When i was running memcpy for A5, there was some issue and upon checking the memcpy implementation some floating instruction was used and was causing the problem, later i changed the FPU information in the makefile of A5, then memcpy was executing successfully.
Actually i am using already available applications and trying to measure time taken by memcpy... So dont have much knowledge.
