What are the advantages of fixed-point over floating-point?
Size and Power Consumption — The logic circuits of fixed-point hardware are much less complicated than those of floating-point hardware. This means that the fixed-point chip size is smaller with less power consumption when compared with floating-point hardware.
What is the two main advantages of floating-point vs fixed-point number representations?
Floating-point numbers have two advantages over integers. First, they can represent values between integers. Second, because of the scaling factor, they can represent a much greater range of values.
Is fixed-point better than floating-point?
As such, floating-point processing yields much greater precision than fixed-point processing, distinguishing floating-point processors as the ideal DSP when computational accuracy is a critical requirement.
What is the difference between fixed-point and floating-point representation?
In fixed point notation, there are a fixed number of digits after the decimal point, whereas floating point number allows for a varying number of digits after the decimal point. This representation has fixed number of bits for integer part and for fractional part.
