WebIf you multiply two fixed point values, each of which with 17 bits above the decimal (16 integer and 1 sign) and 15 bits below the decimal, then we end up with an intermediate … WebDSP algorithms often represent the data samples and the coefficients used in the computation as fractional numbers (between -1 and +1) to avoid magnitude growth of a multiplication product. Fractional data type, where there are zero integer bits, is a subset of the more general fixed-point data type.
A fixed point (sometimes shortened to fixpoint, also known as an invariant point) is a value that does not change under a given transformation.
