less power.

Is there any study/paper which details out the design choices, one makes
especially with respect to low power, for MAC implementation.

Stupident takes the datasheet and reads.

I don't know if a hardware MAC necessarily uses less power -- certainly a one-clock hardware MAC, such as you find in general-purpose DSP chips doesn't.

BTW, MAC is also Media Access Controller. Depending on particilar realization, it can have more or less functionality implemented in hardware.

I guess a lot of it depends on how your putative hardware MAC is designed, vs. how your instruction set is arranged.

Just dying from boredom, are you, Tim?
