without SPLOOP vs with SPLOOP

hi,experts

I had just started to study SPLOOP, there is some doubt.

 See the example below(from the C6000 Programmer's Guide), Without SPLOOP, kernel clock is 2, with SPLOOP, seems to be 6(but "SPLOOP 2").

who can make it clear?

 

thanks.

 

 

  • Don't try to understand all the details of how SPLOOP works.  It is not worth the trouble.  Let the compiler do that for you.  Build with the option --debug_software_pipeline and the compiler emits detailed comments before every software pipeline loop which shows you how the the loop works.

    Thanks and regards,
