MIPS Calculation in AAC, HEAAC,HEAAC v2

I would like to know the MIPS calculation formula's for various versions of AAC, starting from pure AAC, through HEAAC and finally HEAAC v2. I'm familiar with the general eqation given below (for a single frame)

    MIPS = (No of Cycles per frame * Sampling frequency)/(Samples per frame * 1000000)

        But what my doubt is regarding the "Samples per frame" factor in the equation. What value to use for each version and for different channel configuration like single channel and two channel etc..Till now i was using these values irrespective of channel count.
    AAC        - 1024
    HEAAC    - 2048
    HEAAC v2 - 2048

Thanks in advance
