How does the DSPLINK's mode (SWI or TSK) impact the ARM side?

Hi,

DSPLINK can be built either in the SWI mode or TSK mode. I am looking for its impact on the ARM side, i.e. which mode has a better efficiency of CPU resources on ARM side? What is the underlying mechanism to trigger/notify DSPLINK interface on ARM side?

Or this mode selection just impacts the DSP-side?

Thanks,

Wei
