low-power design is all about fancy hardware , but honestly Software plays a big role.
: Clock gating dims the lights on idle modules, while power gating cuts the power completely.
: Try not to overwork your processor. Schedule your tasks efficiently and let it nap in low-power modes. 
: 
: Choose efficient algorithms, use power-saving instructions, and eliminate unnecessary operations. WM
fixed point math instead of floating point when possible, it can save power in some casesWMFloating point calculations require a dedicated FPU in the hardware, that alone can take up more power. Now fixed point math can be done purely in software using integer operations, later on saving power on microcontrollers without an FPU. fixed point has lower precision.W
