Fractional Binary FixedPoint Numbers
In ``DSP chips'' (microprocessors explicitly designed for digital signal processing applications), the most commonly used fixedpoint format is fractional fixed point, also in two's complement.
Quite simply, fractional fixedpoint numbers are obtained from integer fixedpoint numbers by dividing them by . Thus, the only difference is a scaling of the assigned numbers. In the case, we have the correspondences shown in Table G.5.
