Simplified floating-point units for high dynamic range image and video systems
Javier Hormigo, Julio Villalba · 2015
The upcoming arrival of high dynamic range image and video applications to consumer electronics will force the utilization of floating-point numbers on them. This paper shows that introducing a slight modification on classical floating-point number systems, the implementation of those circuits can be highly improved. For a 16-bit numbers, by using the proposed format, the area and power consumption of a floating-point adder is reduced up to 70% whereas those parameters are maintained for the case of a multiplier.
