Abstract
A signal processing apparatus for linear interpolation capable of performing operations to obtain suitable original data even when an interpolation coefficient &agr; is 1.0, wherein a correction term selects A when &agr;=0×FF (&agr;=1.0) and selects B when the bit is 0. The selected data becomes an element of addition by being shifted for the number of bits of &agr;. A product summation operation term uses the upper 8 bits of the result of multiplication of 8 bits×8 bits and shifts the 8-bit result of operation 8 bits to the left so as to enable further addition of the product summation operation term. An adder adds the shifted correction term, the partial products out to out , and the product summation operation term and outputs the upper 8 bits as the result of the operation.
