How should the host communicate with the eTPU?

eTPU_C

There are a few ways:

  • You can pass information through static locals. The host sets these itself, during initialization.

    Use the ::ETPUlocation macro to identify the offset of the static in the function frame. Rather than assigning the value in ::ETPUstaticinit which comes from the eTPU_C program, simply set your own initial value.

    For more information on host interface macros, see the product documentation.
