SDSoC + ZCU102 speedup

Hi,

I am running SDSoC Env Tutorial lab1 in SDSoC 2018.2 on ZCU102. I selected the following settings:

  • System configuration: A53 Linux
  • CPU: a53_linux
  • Active build configuration: Release

When I execute lab1.elf on the device, I get only 0.95765 speedup, whereas in the tutorial, for ZC702 the speedup was around 8 

 

 

Testing 1024 iterations of 32x32 floating point mmultadd...
Average number of CPU cycles running mmultadd in software: 81203
Average number of CPU cycles running mmultadd in hardware: 84794
Speed up: 0.95765
TEST PASSED

Can anyone please say is it normal, since I am trying it on a different board?

 

Thanks

Re: SDSoC + ZCU102 speedup

Hi @immwn

 

Based on board, it will differ, but in your case the speed up difference is too high. The hardware is not helping to accelerate much.

It is same as software, which is not expected. 

 

I will check this on my side and let you know my speedup observation.

 

Best Regards,

Nutan
