Dear CCS champs,
I'm using CCSv5.3.0.00090, my target hardware is a C5515 EVM, and I use the on-board USB emulator. I have two questions with regards to the CCS profile clock. This is the profile clock you can enable by using the CCS menu Run->Clock->Enable.
Q1. I'm used to using this clock when I use the TI simulator and it's pretty easy to see how the simulator can count CPU cycles. However, we can also use this clock with the emulator, at least on the C5515EVM. My Question is, how is this clock determined? I don't recall seeing any kind of free running counter in the C5515 like we have in a C64x+ core. I'm interested in how this works? How does the emulator+CCS count CPU cycles?
Q2. I see discrepencies between stepping over functions and stepping into functions. If I step over a function, I get a certain clock count. However, if I rerun and instead of stepping over that function, I step into and single step my way though it, the total clock count is less. Why do I get less clock counts if I single step my way through a function compared to just stepping over a function? I found a somewhat similar post for a C2000 DSP but it was talking about the simulator and how you don't see the effects of the pipeline when single stepping. Is that the same situation here? I guess if I knew the answer to Q1, that would help understand Q2.
Thanks
